(high: sync protection window released.) xugf is the frame sync obtained from the efm signal, and is negative pulse. it is the signal before sync protection. xplck is the inverse of the efm pll clock. the pll is designed so that the falling edge and the efm signal transition point coincide. the gfs signal goes high when the frame sync and the insertion protection timing match. (see $348.) rfck is derived from the crystal accuracy, and has a cycle of 136 s. (during normal speed) c2po represents the data error status. xraof is generated when the 32k ram exceeds the 28f jitter margin. pin no. 119 120 121 122 123 124 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 i/o i i i i i o i i o i o i o i i i 1, 0 1, 0 1, z, 0 1, 0 gfs is sampled at 460hz; when gfs is high, this pin outputs a high signal. if gfs is low eight consecutive samples, this pin outputs low. input when lkin = high.

?71 CXD3011R-1 [2] subcode interface there are two methods for reading out a subcode externally. the 8-bit subcodes p to w can be read out from sbso by inputting exck. sub-q can be read out after checking crc of the 80 bits in the subcode frame. sub-q can be read out from the sqso pin by inputting 80 clock pulses to the sqck pin when scor comes correctly and crcf is high. ?2-1. p to w subcode readout data can be read out by inputting exck immediately after wfck falls. (see timing chart 2-1.) ?2-2. 80-bit sub-q readout fig. 2-2 shows the peripheral block of the 80-bit sub-q register. first, sub-q, regenerated at one bit per frame, is input to the 80-bit serial/parallel register and the crc check circuit. 96-bit sub-q is input, and if the crc is ok, it is output to sqso with crcf = 1. in addition, 80 bits are loaded into the parallel/serial register. when sqso goes high after scor is output, the cpu determines that new data (which passed the crc check) has been loaded. when the 80-bit data is loaded, the order of the msb and lsb is inverted within each byte. as a result, although the sequence of the bytes is the same, the bits within the bytes are now ordered lsb first. once the 80-bit data load is confirmed, sqck is input so that the data can be read. the sqck input is detected, and the retriggerable monostable multivibrator is reset while the input is low. the retriggerable monostable multivibrator has a time constant from 270 to 400s. when the duration when sqck is high is less than this time constant, the monostable multivibrator is kept reset; during this interval, the serial/parallel register is not loaded into the parallel/serial register. while the monostable multivibrator is being reset, data cannot be loaded in the peak detection parallel/serial register or the 80-bit parallel/serial register. in other words, while reading out with a clock cycle shorter than this time constant, the register will not be rewritten by crcok and others. the previously mentioned peak detection register can be connected to the shift-in of the 80-bit parallel/serial register. for ring control 1, input and output are shorted during peak meter and level meter modes. for ring control 2, input and output are shorted during peak meter mode. this is because the register is reset with each readout in level meter mode, and to prevent readout destruction in peak meter mode. as a result, the 96-bit clock must be input in peak meter mode. the absolute time after peak is stored in the memory in peak meter mode. (see timing chart 2-3.) the high and low intervals for sqck should be between 750ns and 120s.

? 78 CXD3011R-1 [3] description of modes this lsi has three basic operating modes using a combination of spindle control and the pll. the operations for each mode are described below. ?3-1. clv-n mode this mode is compatible with the cxd2510q, and operation is the same as for conventional control (however, variable pitch cannot be used). the pll capture range is 150khz. ?3-2. clv-w mode this is the wide capture range mode. this mode allows the pll to follow the rotational velocity of the disc. this rotational following control has two types: using the built-in vco2 or providing an external vco. the spindle is the same clv servo as for the conventional series. operation using the built-in vco2 is described below. (when using an external vco, input the signal from the vpco pin to the low-pass filter, use the output from the low-pass filter as the control voltage for the external vco, and input the oscillation from the vco to the vcki pin.) when starting to rotate the disc and/or speeding up to the lock range from the condition where the disc is stopped, cav-w mode should be used. specifically, first send $e665x to set cav-w mode and kick the disc, then send $e60cx to set clv-w mode if alock is high, which can be read out serially from the sqso pin. clv-w mode can be used while alock is high. the microcomputer monitors the serial data output, and must return the operation to the speed adjusting state (cav-w mode) when alock becomes low. the control flow according to the microcomputer software in clv-w mode is shown in fig. 3-2. in clv-w mode (normal), low power consumption is achieved by setting lpwr to high. control was formerly performed by applying acceleration and deceleration pulses to the spindle motor. however, when lpwr is set high, deceleration pulses are not output, thereby achieving low power consumption mode. clv-w mode supports control only by the ternary output of the mdp pin. therefore, when using clv-w mode, set dclv pwm md to low. note) the capture range for this mode is theoretically up to the signal processing limit. ?3-3. cav-w mode this is cav mode. in this mode, the external clock is fixed and it is possible to control the spindle to the desired rotational velocity. the rotational velocity is determined by the vp0 to 7 setting values, or the external pwm. when controlling the spindle with vp0 to 7, setting cav-w mode with the $e665x command and controlling vp0 to 7 with the $dx commands allows the rotational velocity to be varied from low speed to 32 speed. (see "$dx commands".) also, when controlling the spindle with the external pwm, the pwmi pin is binary input which becomes kick during high intervals and brake during low intervals. the microcomputer can know the rotational velocity using v16m. the reference frequency for the velocity measurement is a signal of 132.3khz obtained by dividing xtal (xtli, xtlo) (384fs) by 128. the velocity is obtained by counting half of v16m pulses while the reference is high, and the result is output from the new cpu interface as 10 bits (vf0 to 10). these measurement results are 31 when the disc is rotating at normal speed or 127 when it is rotating at quadruple speed. these values match those of the 256 - n for control with vp0 to 7. (see table 2-5 and fig. 2-6.) in cav-w mode, the spindle is set to the desired rotational velocity and the operation speed for the entire system follows this rotational velocity. therefore, the cycles for the fs system clock, pcm data and all other output signals from this lsi change according to the rotational velocity of the disc. note) the capture range for this mode is theoretically up to the signal processing limit. note) set flfc to 1 for this mode.
? 79 CXD3011R-1 ?3-4. vco-c mode this is vco control mode. in this mode, the v16m oscillation frequency can be controlled by setting $d commands vp0 to 7 and vpctl0, 1. the v16m oscillation frequency can be expressed by the following equation. n: vp0 to 7 setting value 1: vpctl0, 1 setting value the vco1 oscillation frequency is determined by v16m. the vco1 frequency can be expressed by the following equation. when dspb = 0 when dspb = 1 1 (256 ?n) v16m = 32 49 vco1 = v16m 24 49 vco1 = v16m 16

? 82 CXD3011R-1 [4] description of other functions ?4-1. channel clock regeneration by the digital pll circuit the channel clock is necessary for demodulating the efm signal regenerated by the optical system. assuming t as the channel clock cycle, the efm signal is modulated in an integer multiple of t from 3t to 11t. in order to read the information in the efm signal, this integer value must be read correctly. as a result, t, that is the channel clock, is necessary. in an actual player, a pll is necessary for regenerating the channel clock because the fluctuation in the spindle rotation alters the width of the efm signal pulses. the block diagram of this pll is shown in fig. 4-1. the CXD3011R-1 has a built-in three-stage pll. the first-stage pll is a wide-band pll. when using the internal vco2, an external lpf is necessary; when not using the internal vco2, external lpf and vco are necessary. the output of this first-stage pll is used as a reference for all clocks within the lsi. the second-stage pll regenerates the high-frequency clock needed by the third-stage digital pll. the third-stage pll is a digital pll that regenerates the actual channel clock. the digital pll in clv-n mode has a secondary loop, and is controlled by the primary loop (phase) and the secondary loop (frequency). when flfc = 1, the secondary loop can be turned off. high frequency components such as 3t and 4t may contain deviations. in such cases, turning the secondary loop off yields better playability. however, in this case the capture range becomes 50khz. a new digital pll has been provided for clv-w mode to follow the rotational velocity of the disc in addition to the conventional secondary loop.

? 84 CXD3011R-1 ?4-2. frame sync protection in normal-speed playback, a frame sync is recorded approximately every 136 s (7.35khz). this signal is used as a reference to recognize the data within a frame. conversely, if the frame sync cannot be recognized, the data is processed as error data because the data cannot be recognized. as a result, recognizing the frame sync properly is extremely important for improving playability. in the cxd3011r, window protection and forward protection/backward protection have been adopted for frame sync protection. these functions achieve very powerful frame sync protection. there are two window widths; one for cases where a rotational disturbance affects the player and the other for cases where there is no rotational disturbance (wsel = 0/1). in addition, the forward protection counter is set to 12 * , and the backward protection counter to 3 * . concretely, when the frame sync is being played back normally and then cannot be detected due to scratches, a maximum of 12 frames are inserted. if the frame sync cannot be detected for 13 frames or more, the window opens to resynchronize the frame sync. in addition, immediately after the window opens and the resynchronization is executed, if a proper frame sync cannot be detected within 3 frames, the window opens immediately. * default values. these values can be set as desired by $c commands sfp0 to 3 and srp0 to 3. ?4-3. error correction in the cd format, one 8-bit data contains two error correction codes, c1 and c2. for c1 correction, the code is created with 28-byte information and 4-byte c1 parity. for c2 correction, the code is created with 24-byte information and 4-byte parity. both c1 and c2 are reed solomon codes with a minimum distance of 5. the CXD3011R-1 uses refined super strategy to achieve double correction for c1 and quadruple correction for c2. in addition, to prevent c2 miscorrection, a c1 pointer is attached to data after c1 correction according to the c1 error status, the playback status of the efm signal, and the operating status of the player. the correction status can be monitored externally. see table 4-2. when the c2 pointer is high, the data in question was uncorrectable. either the pre-value was held or an average value interpolation was made for the data. mnt3 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 no c1 errors; c1 pointer reset one c1 error corrected; c1 pointer reset no c1 errors; c1 pointer set one c1 error corrected; c1 pointer set two c1 errors corrected; c1 pointer set c1 correction impossible; c1 pointer set no c2 errors; c2 pointer reset one c2 error corrected; c2 pointer reset two c2 errors corrected; c2 pointer reset three c2 errors corrected; c2 pointer reset four c2 errors corrected; c2 pointer reset c2 correction impossible; c1 pointer copy c2 correction impossible; c2 pointer set mnt2 mnt1 mnt0 description table 4-2.

? 90 CXD3011R-1 digital audio data input the input signal of the digital audio data is input from the dac input pins pcmdi, lrcki and bcki. the input format supports 32-bit slot/lsb first, 64-bit slot/lsb first and 48-bit slot/msb first. the input format can be selected by $34a command mlsl. * dac supports only 48-bit slot input. in mlsl=0, therefore, dac should be forcibly muted. 1) mlsl = 0 32-bit slot/lsb first, 64-bit slot/lsb first (the dac output requires the forcible muting.) 2) mlsl = 1 48-bit slot/msb first (the dac output is possible at the same time.) mute function by setting the command bit dout_dmut to 1, all the audio data portions in the digital out output can be made to 0 with the channel status data as it is. input/output synchronization circuit in the normal operation, the dac automatically synchronizes with the input lrck. however, when the input data has much jitter or the power is turned on the synchronization may not be achieved. in such a case, the internal operation should be forcibly synchronized by setting $34a dout wod to 1. also, the forcible synchronization is required when the operating frequency is changed such as switching between clv and cav,etc. be sure to set dout wod to 0 before performing forcible synchronization again. * when the synchronization is performed, the internal counter which counts the frames is cleared so that the frame is started from 0 after the synchronization processed. in case where the automatic processing of the synchronization is not desirable or the user wants to do it manually, set the command $34a win en to 0 to invalidate the automatic synchronization circuit. clock system of dout circuit for the dout block, the master clock is set using the clock control command mcsl ($a) employed by the dac block. set mcsl to 1 for 768fs and to 0 for 384fs.

? 92 CXD3011R-1 ?4-6. servo auto sequence this function performs a series of controls, including auto focus and track jumps. when the auto sequence command is received from the cpu, auto focus, 1-track jump, 2n-track jump, fine search and m-track move are executed automatically. the servo block operates according to the built-in program during the auto sequence execution (when xbusy = low), so that does not accept commands from the cpu, that is $0, 1 and 2 commands. ($3 to e commands are accepted.) in addition, when using the auto sequence, turn the a.seq of register 9 on. when clok goes from low to high while xbusy is low, xbusy does not become high for a maximum of 100 s after that point. this is to prevent the transfer of erroneous data to the servo when xbusy changes from low to high by the monostable multivibrator, which is reset by clok being low (when xbusy is low). in addition, a max timer is built into this lsi as a countermeasure against abnormal operation due to external disturbances, etc. when the auto sequence command is sent from the cpu, this command assumes a $4xy format, in which x specifies the command and y sets the max timer value and timer range. if the executed auto sequence command does not terminate within the set timer value, the auto sequence is interrupted (like $40). see [1] "$4x commands" concerning the timer value and range. also, the max timer is invalidated by inputting $4x0. although this command is explained in the format of $4x in the following command descriptions, the timer value and timer range are actually sent together from the cpu. (a) auto focus ($47) focus search-up is performed, fok and fzc are checked, and the focus servo is turned on. if $47 is received from the cpu, the focus servo is turned on according to fig. 4-8. the auto focus starts with focus search-up, and note that the pickup should be lowered beforehand (focus search-down). in addition, blind e of register 5 is used to eliminate fzc chattering. concretely, the focus servo is turned on at the falling edge of fzc after fzc has been continuously high for a longer time than e. (b) track jump 1, 10 and 2n-track jumps are performed respectively. always use this when the focus, tracking, and sled servos are on. note that tracking gain-up and braking-on ($17) should be sent beforehand because they are not involved in this sequence. 1-track jump when $48 ($49 for rev) is received from the cpu, a fwd (rev) 1-track jump is performed in accordance with fig. 4-9. set blind a and brake b with register 5. 10-track jump when $4a ($4b for rev) is received from the cpu, a fwd (rev) 10-track jump is performed in accordance with fig. 4-10. the principal difference from the 1-track jump is to kick the sled. in addition, after kicking the actuator, when 5 tracks have been counted through cout, the brake is applied to the actuator. then, when the actuator speed is found to have slowed up enough (determined by the cout cycle becoming longer than the overflow c set with register 5), the tracking and sled servos are turned on.
? 93 CXD3011R-1 2n-track jump when $4c ($4d for rev) is received from the cpu, a fwd (rev) 2n-track jump is performed in accordance with fig. 4-11. the track jump count n is set with register 7. although n can be set to 2 16 tracks, note that the setting is actually limited by the actuator. cout is used for counting the number of jumps when n is less than 16, and mirr is used with n is 16 or more. although the 2n-track jump basically follows the same sequence as the 10-track jump, the one difference is that after the tracking servo is turned on, the sled continues to move only for "d", set with register 6. fine search when $44 ($45 for rev) is received from the cpu, a fwd (rev) fine search (n-track jump) is performed in accordance with fig. 4-12. the differences from a 2n-track jump are that a higher precision is achieved by controlling the traverse speed, and a longer distance jump is achieved by controlling the sled. the track jump count is set with register 7. n can be set to 2 16 tracks. after kicking the actuator and sled, the traverse speed is controlled based on the overflow g. set kick d and f with register 6 and overflow g with register 5. also, sled speed control during traverse can be turned off by causing comp to fall. set the number of tracks which comp falls with register b. after n tracks have been counted through cout, the brake is applied to the actuator and sled. (this is performed by turning on the tracking servo for the actuator, and by kicking the sled in the opposite direction during the time for kick d set with register 6.) then, the tracking and sled servos are turned on. set overflow g to the speed required to slow up just before the track jump terminates. (the speed should be such that it will come on-track when the tracking servo turns on at the termination of the track jump.) for example, set the target track count n ? a for the traverse monitor counter which is set with register b, and comp will be monitored. when the falling edge of this comp is detected, overflow g can be reset. m-track move when $4e ($4f for rev) is received from the cpu, a fwd (rev) m-track move is performed in accordance with fig. 4-13. m can be set to 2 16 tracks. like the 2n-track jump, cout is used for counting the number of moves when m is less than 16, and mirr is used when m is 16 or more. the m-track move is executed by moving only the sled, and is therefore suited for moving across several thousand to several ten-thousand tracks. in addition, the track and sled servos are turned off after m tracks have been counted through cout or mirr unlike for the other jumps. transfer $25 from the microcomputer after the actuator has stabilized.

? 104 CXD3011R-1 dac block mute operation soft mute soft mute results and the input data is attenuated to zero when any one of the following conditions is met. when attenuation data of 000 (hex) is set when the $9x commands dac smutl and dac smutr are set to 1 forced mute forced mute results when the $ax command fmut is set to 1. forced mute fixes the pwm output. (low for left channel , high for right channel) zero detection mute setting $9x command zmut to 1 enables forced mute, when zero data is detected for both the left and right channels. (see "zero data detection".) lrck synchronization synchronization is performed at the first rising edge of the lrck input when reset. after that, synchronization is lost when the lrck input frequency changes, etc., so resynchronization must be performed. the lrck input frequency changes when the master clock of the lsi is switched and the playback speed changes such as the following cases. ?when the xtsl pin switches between high and low ?when the $9x command dspb setting changes ?when the $9x command mcsl setting changes ?when operation switches between clv mode and cav mode lrck switching may also be performed if there are other ics between the cd-dsp block and the dac block. resynchronization must be performed in these cases as well. for resynchronization, set the $9x command xwoc to 0 or the external pin xwo to low, wait for one lrck cycle or more, and then set xwoc to 1 and xwo to high. * when setting xwoc to 0 or the external pin xwo to low, be sure to set the $9x command sycof to 0 beforehand. s o f t m u t e o n s o f t m u t e o f f s o f t m u t e o f f 2 3 . 2 [ m s ] 2 3 . 2 [ m s ] 0 d b d b

(see timing chart 5-2.) monitoring requires that the upper 8 bits of the command register are 38 (hex). x l a t s e n s ( = x a v e b s y ) m a x . 1 s a v r g m e a s u r e m e n t c o m p l e t e d 2 . 9 t o 5 . 8 m s timing chart 5-2. vc avrg: the vc dc offset (vc avrg) which is the center voltage for the system is measured and used to compensate the fe, te and se signals. fe avrg: the fe dc offset (fe avrg) is measured and used to compensate the fe and fzc signals. te avrg: the te dc offset (te avrg) is measured and used to compensate the te and se signals. rf avrg: the rf dc offset (rf avrg) is measured and used to compensate the rfdc signal. rflc: (rf signal ?rf avrg) is input to the rf in register. "00" is input when the rf signal is lower than rf avrg. tlc0: (te signal ?vc avrg) is input to the trk in register. tlc1: (te signal ?te avrg) is input to the trk in register. vclc: (fe signal ?vc avrg) is input to the fcs in register. flc1: (fe signal ?fe avrg) is input to the fcs in register. flc0: (fe signal ?fe avrg) is input to the fzc register. two methods of canceling the dc offset are assumed for the cxd3011r. these methods are shown in figs. 5-3a and 5-3b. an example of avrg measurement and compensation commands is shown below. $38 08 00 (rf avrg measurement) $38 20 00 (fe avrg measurement) $38 00 10 (te avrg measurement) $38 14 0a (compensation on [rflc, flc0, flc1, tlc1], corresponds to fig. 5-3a.) see the description of $38 for these commands.
? 111 CXD3011R-1 ?5-4. e:f balance adjustment function (see fig. 5-3.) when the disc is rotated with the laser on, and with the fcs (focus) servo on via fcs search (focus search), the traverse waveform appears in the te signal due to disc eccentricity. in this condition, the low-frequency component can be extracted from the te signal using the built-in trk hold filter by setting d5 (tblm) of $38 to 1. the extracted low-frequency component is loaded into the trvsc register as a digital value, and the trvsc register value is established when tblm returns to 0. next, setting d2 (tlc2) of $38 to 1 compensates the values obtained from the te and se input pins with the trvsc register value (subtraction), allowing the e:f balance offset to be adjusted. (see fig. 5-3.) ?5-5. fcs bias (focus bias) adjustment function the fbias register value can be added to the fcs servo filter input by setting d14 (fbon) of $3a to 1. (see fig. 5-3.) when d11 = 0 and d10 = 1 is set by $34f, the fbias register value can be written using the 9-bit value of d9 to d1 (d9: msb). in addition, the rf jitter can be monitored by setting the $8 command soct1, soct0. (see "dsp block timing chart".) the fbias register can be used as a counter by setting d13 (fbss) of $3a to 1. the fbias register functions as an up counter when d12 (fbup) of $3a = 1, and as a down counter when d12 (fbup) of $3a = 0. the number of up and down steps can be changed by setting d11 and d10 (fbv1 and fbv0) of $3a. when using the fbias register as a counter, the counter stops when the value set beforehand in fbl9 to 1 of $34 matches the fcsbias value. also, if the upper 8 bits of the command register are $3a at this time, sens goes to high and the counter stop can be monitored. a b c f b i a s s e t t i n g v a l u e ( f b 9 t o 1 ) l i m i t v a l u e ( f b l 9 t o 1 ) s e n s p i n a : r e g i s t e r m o d e b : c o u n t e r m o d e c : c o u n t e r m o d e ( w h e n s t o p p e d ) here, assume the fbias setting value fb9 to 1 and the fbias limit value fbl9 to 1 are set in status a. for example, if command registers fbup = 0, fbv1 = 0, fbv0 = 0 and fbss = 1 are set from this status, down count starts from status a and approaches the set limit value. when the limit value is reached and the fbias value matches fbl9 to 1, the counter stops and the sens pin goes to high. note that the up/down counter counts at each sampling cycle of the focus servo filter. the number of steps by which the count value changes can be selected from 1, 2, 4 or 8 steps by fbv1 and fbv0. when converted to fe input, 1 step corresponds to 1/512 v dd /2.

? 113 CXD3011R-1 ?5-6. agcntl (automatic gain control) function the agcntl function automatically adjusts the filter internal gain in order to obtain the appropriate servo loop gain. agcntl not only copes with the sensitivity variation of the actuator and photo diode, etc., but also obtains the optimal gain for each disc. the agcntl command is sent when each servo is turned on. during agcntl operation, if the upper 8 bits of the command register are 38 (hex), the completion of agcntl operation can be confirmed by monitoring the sens pin.

? 114 CXD3011R-1 agcntl and default operation have two stages. in the first stage, rough adjustment is performed with high sensitivity for a certain period of time (select 256/128ms with aght, when mck = 128fs), and the agcntl coefficient approaches the appropriate value. the sensitivity at this time can be selected from two types with agv1. in the second stage, the agcntl coefficient is finely adjusted with relatively low sensitivity to further approach the appropriate value. the sensitivity for the second stage can be selected from two types with agv2. in the second stage of default operation, when the agcntl coefficient reaches the appropriate value and stops changing, the CXD3011R-1 confirms that the agcntl coefficient has not changed for a certain period of time (select 63/31ms with aghj, when mck = 128fs), and then completes agcntl operation. (self stop mode) this self-stop mode can be canceled by setting ags to 0. in addition, the first stage is omitted for agcntl operation when aghs is set to 0. an example of agcntl coefficient transitions during agcntl operation with various settings is shown in fig. 5-5. i n i t i a l v a l u e s e n s a g c n t l s t a r t a g c n t l c o m p l e t i o n c o n v e r g e n c e v a l u e a g c n t l c o e f f i c i e n t v a l u e s l o p e a g v 1 a g h t a g j s l o p e a g v 2 fig. 5-5. note) fig. 5-5 shows the case where the agcntl coefficient converges from the initial value to a smaller value.

(see table 5-17.) sld servo the sld mov (sled move) output, composed of a basic value from 6 bits (d13 to d8) of $37, is determined by multiplying this value by 1 , 2 , 3 , or 4 magnification set using d17 and d16 when d18 = d19 = 0 is set with $3. (see table 5-10.) sld mov must be performed continuously for 50 s or more. in addition, if the lock input signal goes low when the sld servo is on, the sld servo turns off. note) when the lock signal is low, the trk servo switches to gain-up mode and the sld servo is turned off. these operations are disabled by setting d6 (lksw) of $38 to 1. register name command d23 to d20 d19 to d16 0 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1 sled kick level (basic value 1) sled kick level (basic value 2) sled kick level (basic value 3) sled kick level (basic value 4) 0 0 1 1 select 3 table 5-10. * : don't care 0 0 * * 0 1 * * 1 0 * * 1 1 * * * * 0 0 * * 0 1 * * 1 0 * * 1 1

(see fig. 5-11.) the bottom hold speed and mirror sensitivity can be selected from 4 values using d7 and d6, and d5 and d4, respectively, of $3c. r f p e a k h o l d b o t t o m h o l d p e a k h o l d b o t t o m h o l d m i r r m i r r c o m p ( m i r r o r c o m p a r a t o r l e v e l ) h l r f p e a k h o l d 1 p e a k h o l d 2 p e a k h o l d 1 d f c t ( d e f e c t c o m p a r a t o r l e v e l ) h l s d f p e a k h o l d 2 fig. 5-11. dfct signal generation the loaded rf signal is input to two peak hold circuits with different time constants, and the dfct signal is generated by comparing the difference between these two peak hold waveforms with the dfct comparator level.

? 118 CXD3011R-1 ?5-10. dfct countermeasure circuit the dfct countermeasure circuit maintains the directionality of the servo so that the servo does not become easily dislocated due to scratches or defects on discs. specifically, these operations are achieved by detecting scratches and defects with the dfct signal generation circuit, and when dfct goes high, applying the low-frequency component of the error signal before dfct went high to the fcs and trk servo filter inputs. (see fig. 5-13.) in addition, these operations are activated by the default. they can be disabled by setting d7 (dfsw) of $38 to 1. i n p u t r e g i s t e r h o l d r e g i s t e r e n h o l d f i l t e r s e r v o f i l t e r e r r o r s i g n a l d f c t fig. 5-13. ?5-11. anti-shock circuit when vibrations occur in the cd player, this circuit forces the trk filter to switch to gain-up mode so that the servo does not become easily dislocated. this circuit is for systems which require vibration countermeasures. concretely, vibrations are detected using an internal anti-shock filter and comparator circuit, and the gain is increased. (see fig. 5-14.) the comparator level is fixed to 1/16 of the maximum comparator input amplitude. however, the comparator level is practically variable by adjusting the value of the anti-shock filter output coefficient k35. this function can be turned on and off by d19 of $1 when the brake circuit (described hereafter) is off. (see table 5-17.) this circuit can also support an external vibration detection circuit, and can set the trk servo filter to gain-up mode by inputting high level to the atsk pin. when the upper 8 bits of the command register are $1, vibration detection can be monitored from the sens pin. t e a n t i s h o c k f i l t e r t r k g a i n u p f i l t e r t r k g a i n n o r m a l f i l t e r t r k d a c a t s k s e n s c o m p a r a t o r fig. 5-14.
? 119 CXD3011R-1 ?5-12. brake circuit immediately after a long distance track jump it tends to be hard for the actuator to settle and for the servo to turn on. the brake circuit prevents these phenomenon. in principle, the brake circuit uses the tracking drive as a brake by cutting the unnecessary portions utilizing the 180 offset in the rf envelope and tracking error phase relationship which occurs when the actuator traverses the track in the radial direction from the inner track to the outer track and vice versa. (see figs. 5-15 and 5-16.) concretely, this operation is achieved by masking the tracking drive using the trkcncl signal generated by loading the mirr signal at the edge of the tzc (tracking zero cross) signal. the brake circuit can be turned on and off by d18 of $1. (see fig. 5-17.) in addition, the low frequency for the tracking drive after masking can be boosted.

? 120 CXD3011R-1 ?5-13. cout signal the cout signal is output to count the number of tracks during traverse, etc. it is basically generated by loading the mirr signal at both edges of the tzc signal. the used tzc signal can be selected from among three different phases according to the cout signal application. hptzc: for 1-track jumps fast phase cout signal generation with a fast phase tzc signal. (the tzc phase is advanced by a cut-off 1khz digital hpf; when mck = 128fs.) stzc: for cout generation when mirr is externally input and for applications other than cout generation. this is generated by sampling the te signal at 700khz. (when mck = 128fs) dtzc: for high-speed traverse reliable cout signal generation with a delayed phase stzc signal. since it takes some time to generate the mirr signal, it is necessary to delay the tzc signal in accordance with the mirr signal delay during high-speed traverse. the cout signal output method is switched with d15 and d14 of $3c. when d15 = 1: stzc when d15 = 0 and d14 = 0: hptzc when d15 = 0 and d14 = 1: dtzc when dtzc is selected, the delay can be selected from two values with d14 of $36. ?5-14. serial readout circuit the following measurement and adjustment results can be read out from the sens pin by inputting the readout clock to the sclk pin by $39.

(the coefficient ram cannot be rewritten during this period.) after that, the characteristics of each built-in filter can be finely adjusted by rewriting the data for each address of the coefficient ram. the coefficient rewrite command is comprised of 24 bits, with d14 to d8 of $34 as the address (d15 = 0) and d7 to d0 as data. coefficient rewriting is completed 11.3 s (when mck = 128fs) after the command is received. when rewriting multiple coefficients, be sure to wait 11.3 s (when mck = 128fs) before sending the next rewrite command.
