(see ?. subcode interface.) the last 16 bits are lsb first, which are 15-bit pcm data (absolute values) and l/r flag. l/r flag is high when the 15-bit pcm data is from the left channel and low from the right channel. pcm data is reset zero and the l/r flag is reversed after one readout. then level measuring continues until the next readout.
?40 CXD2586R/-1 description of peak meter mode (see the timing chart 1-5.) when the lsi is set to this mode, the maximum pcm data value is detected regardless of if it comes from the left or right channel. the 96-bit clock must be input to sqck to read out this data. when the 96-bit clock is input, 96 bits of data are output to sqso and the lsi internal register is set the value again. in other words, the pcm maximum value detection register is not reset to zero by the readout. to reset the pcm maximum value register to zero, set pct1 = pct2 = 0 or set the $ax mute. the sub q absolute time is automatically controlled in this mode. in other words, after the maximum value is generated, the absolute time for crc to become ok is retained in the memory. normal operation is conducted for the relative time. the final bit (l/r flag) of the 96-bit data is normally 0. the pre-value hold and average value interpolation data are fixed to level (? ) in this mode. sens output switching this enables the sqso pin signal to be output from the sens pin. when soc2 = 0, sens output is performed as usual. when soc2 = 1, the sqso pin signal is output from the sens pin. at this time, the readout clock is input to the sclk pin. note) soc2 should be switched when sqck = sclk = high. command bit dads = 0 dads = 1 set to 0 when crystal = 33.8688mhz. set to 1 when crystal = 16.9344mhz. processing command bit soc2 = 0 soc2 = 1 the sens signal is output from the sens pin as usual. the sqso pin signal is output from the sens pin. processing

(when common attenuation data is specified, the attenuation values for channel 1 is used.) an attenuation value, from 00(h) to ff(h), is determined according to the following expression: att = 20 log [input data/255] db example: when the attenuation data is fa(h): att = 20 log [250/255] db = ?.172db soft mute with the soft mute function, when the attenuation data goes from ff(h) to 00(h) and vice versa, muting is turned on and off over the muting time of 1024fs [s] = 23.2 [ms] (fs = 44.1khz). attenuation assume the attenuation data att1, att2, and att3, where att1 > att3 > att2. first, assume att1 is transferred and then att2 is transferred. if att2 is transferred before att1 is reached (state "a" in the diagram), then the value continues approaching att2. next, if att3 is transferred before att2 is reached (state "b" or "c" in the diagram), the attenuation begins approaching att3 from the current point. note that it takes 1024/fs [s] (fs = 44.1khz for cd players) to transit between attenuation data (from 0db to ? ). att1 a b c att2 0db att3 handling of the attenuation value

?58 CXD2586R/-1 ?. subcode interface there are two methods for reading out a subcode externally. the 8-bit subcodes p to w can be read 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 sqck pin when scor comes correctly and crcf is high. ?-1. p to w subcode readout data can be read out by inputting exck immediately after wfck falls. (see the timing chart 2-1.) ?-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 has been inputted, and if the crc is ok, it is output to sqso with crcf = 1. in addition, the 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. in the CXD2586R/-1, when 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 sqso input is detected, and the retriggerable monostable multivibrator for low is reset. 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 s/p register is not loaded into the p/s 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. in this lsi, the previously mentioned peak detection register can be connected to the shift-in of the 80-bit p/s register. input for ring control 1 is connected to the output of it in peak meter or level meter mode. same goes for ring 2 in 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 the timing chart 2-3.) the high and low intervals for sqck should be between 750ns and 120s.

?64 CXD2586R/-1 ?. 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. ?-1. clv-n mode this mode is compatible with the cxd2500 series, and operation is the same (however, variable pitch cannot be used). the pll capture range is 150khz. ?-2. clv-w mode this is the wide capture range mode. this mode allows 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 cxd2500 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.) while starting to rotate a disc and/or speeding up to the lock range from the condition that a disc stops, cav-w mode should be used. concretely saying, firstly send $e665x to set cav-w mode and kick a disc, secondly send $e60cx to set clv-w mode if alock is high, which can be read serially from sqso pin. clv-w mode can be used while alock is high. the microcomputer monitors the serial data output, and must return to adjust speed operation (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 to 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. cav-w mode this is the cav mode. in this mode, it is possible to control spindle to variable rotational velocity, the external crystal is fixed though. 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 the cav-w mode with $e665x command and controlling vp0 to 7 with the $dx commands allows the rotational velocity to be varied from low speed to sextuple-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. and the reference for the velocity measurement is a signal of 132.2khz obtained by 1/128 of mclk (384fs). the velocity is obtained by counting v16m/2 pulses while the reference is high, and the result is output from the new cpu interface as 8 bits (vp0 to 7). 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.

?66 CXD2586R/-1 ?. description of other functions ?-1. channel clock regeneration by the digital pll circuit the channel clock is needed to demodulate 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, pll is necessary to regenerate the channel clock because the fluctuation in the spindle rotation alters the width of the efm signal pulses. practically, pll is necessary to regenerate the channel clock, because the efm pulse width is altered by spindle rotation fluctuation. the block diagram of this pll is shown in fig. 4-1. the CXD2586R/-1 has a built-in three-stage pll. the first-stage pll is for the wide-band pll. when the built-in vco2 is used, lpf is required externally. when the built-in vco2 is not used, lpf and vco are required externally. the output of this first-stage pll is used as a reference for all clocks within the lsi. the second-stage pll generates a 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, which is the primary loop (phases) 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 a case, turning the secondary loop off yields better playability. however, in this case the capture range becomes 50khz. the new digital pll in clv-w mode follows the rotational velocity of the disc, in addition to the above- mentioned secondary loop.

?68 CXD2586R/-1 ?-2. frame sync protection in normal speed playback, a frame sync is recorded approximately every 136s (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 CXD2586R/-1, 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 fixed to 13, and the backward protection counter to 3. concretely, when the frame sync has been played back normally and then cannot be detected due to scratches, a maximum of 13 frames are inserted. if frame sync cannot be detected for 13 frames or more, the window is released and try to resyncronize the frame sync. in addition, immediately after the window is released and the resynchronization is executed, if a proper frame sync cannot be detected within 3 frames, the window is released immediately. ?-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 CXD2586R/-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 the 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.

?73 CXD2586R/-1 ?-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 jumps, fine search, and m track move are executed automatically. servo is used in an exclusive manner during the auto sequence execution (when xbusy = low), so that commands from the cpu are not transferred to the servo, but can be sent to the CXD2586R/-1. 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 100s 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 in 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 ?, $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 focus, tracking and sled servo 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 in register 5), the tracking and sled servos are turned on.
?74 CXD2586R/-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 in 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 when 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 in 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 a higher precision jump achieved by controlling the traverse speed and a longer distance jump achieved by controlling the sled. the track jump count is set in 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 in register 6 and overflow g in register 5. also, sled speed control during traverse can be turned off by causing comp to fall. set the number of tracks during which comp falls in 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 in 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 in 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. 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 only by moving the sled, and is therefore suited for moving across several thousand to several ten-thousand tracks. in addition, the track and sled servo are turned off after m tracks have been counted through cout or mirr unlike for the other jumps. transfer $25 after the actuator is stabled.

(see the timing chart 5-2.) xlat sens (= xavebsy) max. 1s completion of avrg measurement 2.9 to 5.8ms timing chart 5-2.
?88 CXD2586R/-1 vc avrg the offset can be canceled by measuring the vc level which is the center voltage for the system and using that value to apply compensation to each input error signal. fe avrg CXD2586R/-1 measures the fe signal dc level, and can apply it to compensate the fzc comparator level output from the sens pin during fcs search (focus search) using these measurement results. te avrg this measures the te signal dc level. re avrg the CXD2586R/-1 generates the mirr, dfct and fok signals from the rf signal. however, the fok signal is generated by comparing the rf signal at a certain level, so that it is necessary to establish a zero level which becomes the comparator level reference. therefore, the rf signal is measured before playback operation, and compensation is applied to bring this level to the zero level. an example of sending avrg measurement and compensation commands is shown below. (example) $380800 (rf avrg. measurement on) $382000 (fe avrg. measurement on) $380010 (te avrg. measurement on) $388000 (vc avrg. measurement on) (complete each avrg measurement before starting the next.) $38140a (rflc, flc0, flc1 and tlc1 commands on) (the required compensation should be turn on together; see fig. 5-3.) an interval of 5.8ms or more must be maintained between each command, or the sens pin must be monitored to confirm that the previous command has been completed before the next avrg command is sent. see fig. 5-3 for the contents of each compensation below. rflc the difference by which the rf signal exceeds the rf avrg value is input to the rf in register. (00 is input when the rf signal is lower than the rf avrg value.) tcl0 the value obtained by subtracting the vc avrg value from the te signal is input to the trk in register. tcl1 the value obtained by subtracting the te avrg value from the te signal is input to the trk in register. vclc the value obtained by subtracting the vc avrg value from the fe signal is input to the fcs in register. flc1 the value obtained by subtracting the fe avrg value from the fe signal is input to the fcs in register. flc0 the value obtained by subtracting the fe avrg value from the fe signal is input to the fzc register.

(see fig. 5-3.) ?-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. 3-3.) when the fbias register value is set to d11 = 0 and d10 = 1 by $34f, data 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 scot command of $8 to 1. (see the dsp block timing chart.) the fbias register can be used as a counter by setting d13 (fbss) of $3a to 1. it works as an up/down counter. the fbias register works 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 10 (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 serial command are $3a at this time, the counter stop can be monitored through sens. abc fbias setting value (fb9 to 1) limit value (fbl9 to 1) sens pin a: register mode b: counter mode c: counter mode (when stopped) here, the fbias setting values fb9 to 1 and the fbias limit values fbl9 to 1 are assumed to be 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 changes with 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 approximately 3.9 [mv].

?91 CXD2586R/-1 ?-6. agcntl (automatic gain control) function the agcntl function automatically adjusts the filter internal gain in order to obtain the appropriate gain with the servo loop. 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 serial command are 38 (hex), the completion of agcntl operation can be confirmed through the sens pin. (see the timing chart 5-4 and the description of sens signals.) setting d9 and d8 of $38 to 1 set fcs (focus) and trk (tracking) respectively to agcntl operation. note) during agcntl operation, each servo filter gain must be normal, and the anti-shock circuit (described hereafter) must be disabled. xlat sens (= agok) max. 11.4s agcntl termination timing chart 5-4. coefficient k13 changes for agf (focus agcntl) and coefficients k23 and k07 changes for agt (tracking agcntl) due to agcntl. these coefficients change from 01 to 7f (hex), and they must also be set within this range when written externally. after agcntl operation has terminated, these coefficient values can be confirmed by reading them out from the sens pin with the serial readout function (described hereafter). agcntl related setting the following settings can be changed with $35, $36 and $37. fg6 to fg0; agf convergence gain setting, effective setting range: 00 to 57 (hex) tg6 to tg0; agt convergence gain setting, effective setting range: 00 to 57 (hex) ags; self-stop on/off agj; convergence completion judgment time aggf; internally generated sine wave amplitude (agf) aggt; internally generated sine wave amplitude (agt) agv1; agcntl sensitivity 1 (during high sensitivity adjustment) agv2; agcntl sensitivity 2 (during low sensitivity adjustment) aghs; high sensitivity adjustment on/off aght; high sensitivity adjustment time note) converging servo loop gain values can be changed with the fg6 to 0 and tg6 to 0 setting values. in addition, these setting values must be within the effective setting range. the default settings aim for 0db at 1khz. however, since convergence values vary according to the characteristics of each constituent element of the servo loop, fg and tg values should be set as necessary.
?92 CXD2586R/-1 agcntl and default operation have two stages. in the first stage, high sensitivity adjustment is performed for a certain period of time (select 256/128ms with aght), and the agcntl coefficient approaches the appropriate value roughly. the sensitivity at this time can be selected from two types with agv1. in the second stage, the agcntl coefficient approaches the appropriate value finely with relatively low sensitivity. 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 CXD2586R/-1 confirms that the agcntl coefficient has not changed for a certain period of time (select 63/31ms with aghj), and then terminates 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 and the relationship between the various settings are shown in fig. 5-5. initial value sens agcntl start agcntl completion convergence value agcntl coefficient value slope agv1 aght agj slope agv2 fig. 5-5.

(see table 5-17.) sld servo the sld mov (sled move) output, composed of a basic value from the 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 d19 = d18 = 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 is set gain-up status and the sld servo is turned off, by the default. this is disabled by setting d6 (lksw) of $38 to 1. 00 00 00 01 00 10 00 11 sled kick level (basic value ?) sled kick level (basic value ?) sled kick level (basic value ?) sled kick level (basic value ?) 00 11 select 3 table 5-10. * : don? care register name command d23 to d20 d19 to d16 register name command d23 to d20 d19 to d16
?95 CXD2586R/-1 ?-9. mirr and dfct signal generation the rf signal obtained from the rfdc pin is sampled at approximately 1.4mhz and loaded. the mirr and dfct signals are generated from this rf signal. mirr signal generation the loaded rf signal is applied to peak hold and bottom hold circuits. an envelope is generated from the waveforms generated in these circuits, and the mirr comparator level is generated from the average of these envelope waveforms. the mirr signal is generated by comparing this mirr comparator level with the waveform generated by subtracting the bottom hold value from the peak hold value.

(see fig. 5-12.) the dfct comparator level can be selected from four values using d13 and d12 of $3b. fig. 5-12.
?96 CXD2586R/-1 ?-10. dfct countermeasure circuit the dfct countermeasure circuit performs operations to maintain 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 performing scratch and defect detection 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 or by inputting high level to the dfsw pin. input register hold register hold filter servo filter en error signal dfct fig. 5-13. ?-11. anti-shock circuit when vibrations are produced in the cd player, this circuit forces the trk filter to assume gain-up status 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 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 also set the trk servo filter to gain-up status by inputting high level to the atsk pin. when the serial command is $1, vibration detection can be monitored from the sens pin. te anti shock filter trk gain up filter trk gain normal filter trk pwm gen atsk sens comparator fig. 5-14.
?97 CXD2586R/-1 ?-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, this circuit cuts unnecessary portions of the tracking drive and works it as the brake by 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.

?98 CXD2586R/-1 ?-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. however, the used tzc signal can be selected and there are two types of output methods according to the cout signal application. for 1-track jumps, etc. fast phase cout signal with a fast phase tzc signal. for high-speed traverse reliable cout signal with a delayed phase tzc signal. this is because some time is required to generate the mirr signal, and 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 d16 when d19 = d18 = 1 and d17 = 0 are set with $3. (when d16 = 1, for delayed phase and high-speed traverse.) in addition, the tzc signal delay can be selected from two values with d14 of $36. ?-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.

?99 CXD2586R/-1 ?-15. writing the coefficient ram the coefficient ram can be rewritten by $34. all coefficients have default values in the built-in rom, and transfer from the rom to the ram is completed approximately 40s after the xrst pin rises. (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. ?-16. pwm output fcs, trk and sld outputs are output as pwm waveforms. in particular, fcs and trk permit accurate drive by using a double oversampling noise shaper. timing chart 5-20 and figs. 5-21 and 5-22 show examples of output waveforms and drive circuits. the on signal (fon and ron) is active low. t mck = 180ns timing chart 5-20. 64t mck 64t mck 64t mck at mck 1t mck at mck sfon sfdr sron srdr sld 32t mck 32t mck 32t mck 32t mck 32t mck 32t mck 1t mck 1t mck 1t mck 1t mck ffon/ tfon fcs/trk ffdr/ tfdr fron/ tron frdr/ trdr output value +a output value ? output value 0 1t mck t mck a 2 t mck a 2 t mck a 2 t mck a 2 mck (5.6448mhz) - - - - - - - 1 5.6448mhz
