(see timing chart 2-2.) the high and low intervals for sqck should be between 750ns and 120s. 47 CXD3017Q block diagram 2-1 subq sin a b c d e f g h (afram) h g f e d c b a (asec) (amin) 80bit s/p

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. 3-1. the CXD3017Q has a built-in three-stage pll. the first-stage pll regenerates the high-frequency clock needed by the second-stage digital pll. the second-stage pll is a digital pll that regenerates the actual channel clock. block diagram 3-1 x'tal

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 CXD3017Q, 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 is being played back normally and then cannot be detected due to scratches, a maximum of 13 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. ?-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 CXD3017Q's sec strategy uses powerful frame sync protection and c1 and c2 error correction to achieve high playability. the correction status can be monitored externally. see table 3-2. 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 1 1 1 mnt1 0 0 1 0 0 1 mnt0 0 1 1 0 1 0

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. auto focus focus search up fok = h no yes fzc = h no yes fzc = l no yes end focus servo on (check whether fzc is continuously high for

always use this when the focus, tracking, and sled servos are on. note that tracking gain-up and braking-on 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. 3-7. 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. 3-8. 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. 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. 3-9. 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. 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. n-track move when $4e ($4f for rev) is received from the cpu, a fwd (rev) n-track move is performed in accordance with fig. 3-10. n can be set to 2 16 tracks. cout is used for counting the number of jumps. the n-track move is executed only by moving the sled, and is therefore suited for moving across several thousand to several ten-thousand tracks. xlat fok (fzc) busy command for dssp

(see timing chart 4-4 and "description of sens signals".) setting d9 and d8 of $38 to 1 sets 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 completion timing chart 4-4 coefficient k13 changes for agf (focus agcntl) and coefficients k23 and k07 change for agt (tracking agcntl) due to agcntl. these coefficients change from 01 to 7f (h), and they must also be set within this range when written externally. after agcntl operation has completed, these coefficient values can be confirmed by reading them out from the sens pin with the serial readout function (described hereafter). agcntl related settings the following settings can be changed with $35, $36 and $37. fg6 to fg0; agf convergence gain setting, effective setting range: 00 to 57 (h) tg6 to tg0; agt convergence gain setting, effective setting range: 00 to 57 (h) 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 rough adjustment) agv2; agcntl sensitivity 2 (during fine adjustment) aghs; rough adjustment on/off aght; fine adjustment time note) converging servo loop gain values can be changed with the fg6 to fg0 and tg6 to tg0 setting values. in addition, these setting values must be within the effective setting range. the default settings aim for 0 db 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. 75 CXD3017Q agcntl default operation has 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 CXD3017Q 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. 4-5. initial value sens agcntl start agcntl completion convergence value agcntl coefficient value slope agv1 aght agj slope agv2 fig. 4-5 note) fig. 4-5 shows the case where the agccntl coefficient converges from the initial value to a smaller value. 76 CXD3017Q ?-7. fcs servo and fcs search (focus search) the fcs servo is controlled by the 8-bit serial command $0x.

(see fig. 4-11.) the bottom hold speed and mirror sensitivity can be selected from four values using d7 and d6, and d5 and d4, respectively, of $3c. rf peak hold bottom hold peak hold bottom hold mirr mirr comp (mirror comparator level) h l rf peak hold1 peak hold2 peak hold bottom hold dfct (defect comparator level) h l sdf fig. 4-11 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.

(see fig. 4-14.) 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 4-17.) 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 4 bits of the command register are 1 (h), vibration detection can be monitored from the sens pin. it can also be monitored from the atsk pin by setting $3f command asot to 1. te anti shock filter trk gain up filter trk gain normal filter trk pwm gen. atsk sens comparator 80 CXD3017Q ?-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. 4-15 and 4-16.) 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 table 4-17.) in addition, the low frequency for the tracking drive after masking can be boosted.

(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. ?-14. serial readout circuit the following measurement and adjustment results specified beforehand by serial command $39 can be read out from the sens pin by inputting the readout clock to the sclk pin.

(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 the data. coefficient rewriting is completed 11.3s (when mck = 128fs) after the command is received. when rewriting multiple coefficients continuously, be sure to wait 11.3s (when mck = 128fs) before sending the next rewrite command. 83 CXD3017Q ?-17. servo status changes produced by lock signal when the lock signal becomes low, the trk servo switches to the gain-up mode and the sld servo turns off in order to prevent sld free-running. setting d6 (lksw) of $38 to 1 deactivates this function. in other words, neither the trk servo nor the sld servo change even when the lock signal becomes low. this enables microcomputer control. ?-18. description of commands and data sets $34 d15 d14 d13 d12 d11 d10 d9 d8 d7 d6 d5 d4 d3 d2 d1 d0 0 ka6 ka5 ka4 ka3 ka2 ka1 ka0 kd7 kd6 kd5 kd4 kd3 kd2 kd1 kd0 d15 d14 d13 d12 d11 d10 d9 d8 d7 d6 d5 d4 d3 d2 d1 d0 100000 pfok1 pfok0 0 0 0 mrs mrt1 mrt0 00 when d15 = 0. ka6 to ka0: coefficient address kd7 to kd0: coefficient data $348 (preset: $348 000) pfok1 0 0 1 1 0 1 0 1 high when the rfdc value is higher than the fok slice level, low when lower than the fok slice level. high when the rfdc value is higher than the fok slice level, low when continuously lower than the fok slice level for 4.35ms or more. high when the rfdc value is higher than the fok slice level, low when continuously lower than the fok slice level for 10.16ms or more. high when the rfdc value is higher than the fok slice level, low when continuously lower than the fok slice level for 21.77ms or more. pfok0 processing these commands set the fok signal hold time. see $3b for the fok slice level. these are the values when mck = 128fs, and the hold time is inversely proportional to the mck setting. mrs: this command switches the time constant for generating the mirr comparator level of the mirr generation circuit. when 0, the time constant is normal.
