? 34 CXD3009Q 1-2. description of sens output the following signals are output from sens, depending on the microcomputer serial register value (latching not required). note that the sens output can be read out from the sqso pin when soct = 0, sl1 = 1 and sl0 = 0. (see the $bx commands.) 2. subcode interface this section explains the 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 to the CXD3009Q. sub q can be read out after checking the crc of the 80bits 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. 2-1 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, 80bits are loaded into the parallel/serial register. when sqso goes high 400 s (monostable multivibrator time constant) or more after subcode readout, 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 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 s to 400 s. 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 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. (see timing chart 2-2.) the high and low intervals for sqck should be between 750ns and 120 s. sein, a signal input to this lsi from the ssp, is output. low while the auto sequencer is in operation, high when operation terminates. outputs the signal input to the fok pin. normally, fok (from rf) is input. high for "focus ok". sein, a signal input to this lsi from the ssp, is output. high when the regenerated frame sync is obtained with the correct timing. low when the efm signal, after passing through the sync detection filter, is lengthened by 64 channel clock pulses or more. sens pin is fixed to low. calculates the number of tracks from the frequency division ratio set by $b.high when $c is latched; toggles each time cnin is input the number of times set in register b. sein xbusy fok sein gfs ov64 ? cnin division $0x, 1x, 2x, 3x $4x $5x $6x $ax $ex $7x, 8x, 9x, bx, dx, fx $cx microcomputer serial register value (latching not required) sens output meaning

? 39 CXD3009Q 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 cxd2507aq, and operation is the same as for the conventional control. 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 output from the vco to the vcki pin.) while starting to rotate a 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 $e6650 to set cav-w mode and kick the disc, then send $e60c0 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 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. note) the capture range for clv-w mode has theoretically the range 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 $e6650 command and controlling vp0 to 7 with the $dx commands allows the rotational velocity to be varied from low-speed to double-speed. (see the $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 for the velocity measurement is a signal of 132.2khz obtained by dividing the crystal (384fs) by 128. 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 (vf0 to 7). these measurement results are 31 when the disc is rotating at normal speed or 63 when it is rotating at double speed. these values match those of the 256-n for control with vp0 to 7. 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 (excluding dato, clko and xlto). note) the capture range for this mode is theoretically up to the signal processing limit.

? 41 CXD3009Q 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 to regenerate 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 CXD3009Q 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 generates 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. 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.

? 43 CXD3009Q 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 CXD3009Q, 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. 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 CXD3009Q'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 4-1. 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 1 description no c1 errors one c1 error corrected c1 correction impossible no c2 errors one c2 error corrected c2 correction impossible table 4-1.

? 46 CXD3009Q 4-5. digital out there are three digital out formats: the type 1 format for broadcasting stations, the type 2 form 1 format for home use, and the type 2 form 2 format for the manufacture of software. the CXD3009Q supports type 2 form 1. sub q data which are matched twice in succession after a crc check are input to the first four bits (bits 0 to 3) of the channel status. table 4-2. 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 jumps, and n-track move are executed automatically. ssp (servo signal processor lsi) 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 ssp, but can be sent to the CXD3009Q. connect the cpu, rf and ssp as shown in fig. 4-2. 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 ssp when xbusy changes from low to high by the monostable multivibrator, which is reset by clok being low (when xbusy is low). 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 / 1 0 0 0 i d 0 i d 1 c o p y e m p h 0 0 0 0 1 0 0 0 0 0 0 0 f r o m s u b q 0 1 6 3 2 4 8 1 7 6 b i t s 0 t o 3 . . . s u b q c o n t r o l b i t s t h a t m a t c h e d t w i c e w i t h c r c o k b i t 2 9 . . . . . . . . . . 1 w h e n v p o n i s 1 d i g i t a l o u t c b i t 1 2 3 4 5 6 7 8 9 1 0 1 1 1 2 1 3 1 4 1 5

? 48 CXD3009Q fig. 4-3-(b). auto focus timing chart (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 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. 4-4. 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. 4-5. 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 cnin, the brake is applied to the actuator. then, when the actuator speed is found to have slowed up enough (determined by the cnin 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. 4-6. 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. cnin 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. 4-7. n can be set to 216 tracks. cnin is used for counting the number of jumps. this n-track move is executed only by moving the sled, and is therefore suited for moving across several thousand to several ten-thousand tracks. x l t f o k s e i n ( f z c ) b u s y c o m m a n d f o r s s p $ 4 7 l a t c h $ 0 3 b l i n d e $ 0 8

(see the $ax commands.) sycof when lrck, pcmd and bck are connected directly with lrcki, pcmdi and bcki, respectively, playback can be performed easily in cav-w mode by setting sycof of address 9 to 1. normally, the memory proof, etc., is used for playback in cav-w mode. in cav-w mode, the lrck output conforms not to the crystal but to the vco. therefore, synchronization is frequently lost. setting sycof of address 9 to 1 ignores that the lrcki input synchronization is lost, facilitating playback. however, the playback is not perfect because pre-value hold or data skip occurs due to the wow flutter in the lrcki input. * set sycof to 0 except when connecting lrck, pcmd and bck directly with lrcki, pcmdi and bcki, respectively, and performing playback in cav-w mode. * set sycof to 0 in advance when lrck resynchronization is applied with lrwo=1. digital bass boost bass boost without external parts is possible using the built-in digital filter. the boost strength has two levels: mid. and max. bsbst and bbsl of address a are used for the setting. see graph 5-2 for the digital bass boost frequency response.
