In peak detection mode, the SQSO output is connected to the peak detection register. The maximum PCM data values (absolute value, upper 8 bits) for the left and right channels can be read out from SQSO by inputting 16 clocks to SQCK. Peak detection is not performed while inputting to SQCK, and the peak detection register does not change during readout. This SQCK input is judged using a retriggerable monostable multivibrator with a time constant of 270 to 400µs. Set the time for which SQCK input is high to 270µs or less. Peak detection restarts from 270 to 400µs after SQCK input. The peak detection register is reset to zero for each readout (16 clocks input to SQCK). The maximum value during peak detection mode is detected and held in this condition until the next readout. When setting the LSI to peak detection mode, perform readout one time initially to reset the peak detection register. Pre-value hold and average value interpolation data are also detected by peak detection.

– 36 – CXD2529Q 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 out from SBSO by inputting EXCK to the CXD2529Q. Sub Q can be read out after the CRC check of the 80 bits of data in the subcode frame. This is accomplished, after checking SCOR and CRCF, by inputting 80 clock pulses to SQCK and reading out the data from the SQSO pin. 2-1. P to W Subcode Read Data can be read out by inputting EXCK immediately after WFCK falls. (See the Timing Chart 2-1.) 2-2. 80-bit Sub Q Read 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, the 80 bits are loaded into the parallel/serial register. When SQSO goes high 400µs or more (monostable multivibrator time constant) after the subcode is read out, the CPU determines that new data (which passed the CRC check) has been loaded.
  • In the CXD2529Q, when 80-bit data is loaded, the order of the MSB and LSB is inverted for 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 fact that the 80-bit data has been loaded is confirmed, SQCK is input so that the data can be read out. In the CXD2529Q, the SQCK input is detected, and when it is low the retriggerable monostable multivibrator is reset.
  • The retriggerable monostable multivibrator has a time constant from 270 to 400µs. When the duration for which 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 80-bit parallel/serial register. In other words, while reading out with a clock cycle shorter than the monostable multivibrator time constant, the register is not rewritten by CRCOK, etc. (See the Timing Chart 2-2.)
  • Although a clock is input from the SQCK pin to actually perform these operations, the high and low intervals for this clock should be between 750ns and 120µs. 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.

This count is 31 when the disc is rotating at normal speed and 63 when it is rotating at double speed (when DSPB is low). m + 1

– 41 – CXD2529Q 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 the CXD2507AQ. Accordingly, 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 CLV servo like the CXD2507AQ. 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 speed from the condition that a disc stops, CAV-W mode should be used. Specifically, first send $E665X to set CAV-W mode and kick a disc, then send $E60C to set CLV-W mode if ALOCK is high, which can be read out serially from the SQSO pin. CLV-W mode is used for playback 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. 3-3. CAV-W mode This is the CAV mode. In this mode, the external clock is fixed but the spindle rotational velocity can be controlled as desired. 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 the $E665 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 the V16M oscillation frequency. The reference frequency for the velocity measurement is the 132.3kHz signal 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 (VP0 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 (except for DATO, CLKO and XLTO). Note)The capture range for this mode is theoretically up to the signal processing limit.

– 43 – CXD2529Q 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 out 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. The block diagram of this PLL is shown in Fig. 4-1. The CXD2529Q 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 new digital PLL in CLV-W mode follows the rotational velocity of the disc, in addition to the conventional secondary loop.

– 45 – CXD2529Q 4-2. Frame Sync Protection

  • In a CD player operating at normal speed, a frame sync is recorded approximately every 136µs (7.35kHz). This signal is used as a reference to know which data is the data within a frame. Conversely, if the frame sync cannot be recognized, the data is processed as error data because it cannot be recognized what the data is. As a result, recognizing the frame sync properly is extremely important for improving playability.
  • In the CXD2529Q, window protection and forward protection/backward protection have been adopted for frame sync protection. The adoption of these functions achieves 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 is fixed to 3. In other words, when the frame sync is being played back normally and then cannot be detected due to scratches or other problems, a maximum of 13 frames are inserted. If the frame sync cannot be detected for 13 frames or more, the window is released and the frame sync is resynchronized. In addition, immediately after the window is released and resynchronization is executed, if a proper frame sync cannot be detected within 3 frames, the window is released 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 CXD2529Q SEC strategy provides excellent playability through powerful frame sync protection and C1 and C2 error corrections.
  • The correction status can be monitored outside the LSI. See Table 4-1.
  • When the C2 pointer is high, the data in question was uncorrectable. Either the pre-value was held for that data, or an average value interpolation was made. MNT3 MNT1 MNT0

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 CXD2529Q 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 (bit 0 to 3) of the channel status. Table 4-2. 4-6. Servo Auto Sequencer 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 CXD2529Q. 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 100µs after that point. This is designed 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 0/1 0 0 ID0 ID1 COPY Emph 0 0 0 0 1 0 0 0 0 0 0 0 From sub Q0 176 Bits 0 to 3 ...

– 49 – CXD2529Q (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. 4-3. The auto focus starts with focus search-up, and the pickup should be lowered beforehand (focus search-down). In addition, blind E of register 5 is used to eliminate FZC chattering. In other words, the focus servo is turned on at the falling edge of FZC after FZC has been continuously high for a longer time than E. Connection diagram for using auto sequencer (example) Fig. 4-2.

– 50 – CXD2529Q Fig. 4-3-(b). Auto Focus Timing Chart (b) Track Jump 1, 10, and 2N-track jumps are performed respectively. Always use this when focus, tracking, and the sled servo are on. Note that tracking gain-up and braking-on should be sent beforehand because they are not performed.

  • 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 between the 10-track jump and the 1-track jump is whether to kick the sled or not. 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 in 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 in 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 in 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 a maximum of 2 16 tracks. CNIN is used for counting the number of jumps. This N-track move uses a method in which only the sled is moved, and is suited for moves over thousands of tracks.

– 57 – CXD2529Q 5. 1-bit DAC Block 5-1. DAC Block Input Timing Fig. 5-1 shows the input timing for the DAC block. In the CXD2529Q, there is no internal transfer of audio data from the CD signal processing block to the DAC block. Therefore, data can be transferred to the DAC block through an audio DSP or similar device. When data is input to the DAC block without passing through an audio DSP or similar device, data should be connected externally. In this case, EMPH, LRCK, BCK and PCMD can be connected directly with EMPHI, LRCKI, BCKI and PCMDI respectively. 5-2. Description of DAC Block Functions Zero Data Detection When the condition where the lower 4 bits of the input data are DC and the remaining upper bits are all “0” or all “1” continues for approximately 300ms, zero data is detected. Zero data detection is performed independently for the left and right channels. Mute Flag Output The LMUT and RMUT pins become active when any of the following conditions are met. The polarity can be selected by the $9X command ZDPL.

  • When zero data is detected.
  • When a high signal is input to the SYSM pin.
  • When the $AX command SMUT is set. Attenuation Operation Assume attenuation data X1, X2, and X3, where X1 > X3 > X2, and audio outputs Y1, Y2, and Y3, where Y1 > Y3 > Y2. First, assume X1 is transferred and then X2 is transferred. If X2 is transferred before Y1 is reached (state “A” in the diagram), then the value continues approaching Y2. Next, if X3 is transferred before Y2 is reached (either state “B” or “C”), the value begins approaching Y3 from the value at that point (“B” or “C”). A B C 23.2 [ms] – ∞ 00 (H) 0dB 7F (H)

– 59 – CXD2529Q DAC Block Mute Operation Soft mute Soft mute is applied when any of the following conditions are met. Mute is performed, attenuating the input data.

  • When attenuation data is set to 000 (h)
  • When the $AX command SMUT is set to 1
  • When a high signal is input to the SYSM pin Forced mute Forced mute is applied when the $AX command FMUT is set to 1. The PWM output to the LPF block is fixed to low. * Set OPSL2 to 1 for FMUT setting. (See the description of “$AX commands”.) Zero detection mute Forced mute is applied when the $9X command ZMUT is set to 1 and the zero data is detected for the left and right channels. (See the description of “Zero Data Detection”.) LRCK Synchronization Synchronization is performed at the first LRCK input falling edge during reset. When the LRCK input frequency varies, the synchronization is lost. At that time, resynchronization should be executed. The LRCK input frequency varies to the IC master clock switching and playback speed change when the high/low levels of the XTSL pin change, $9 command DSPB setting changes or $9X command MCSL setting changes. Also, LRCK may be switched when there is another IC between the CD DSP block and DAC block. In this case resynchronization is required. In order to perform resynchronization, set the $AX command LRCK to 1 and set LRWO to 0 after one LRCK cycle or more. * Set LRWO with OPSL2 = 1. (See the description of “$AX commands”.) * Set the $9X command SYCOF = 0 in advance when setting LRWO to 1. Soft mute on Soft mute offSoft mute off 0dB –∞ dB

– 60 – CXD2529Q SYCOF Playback can be simply performed by setting SYCOF of address 9 to 1 when LRCK is connected to LRCKI, PCMD to PCMDI and BCK to BCK in CAV-W mode. Normally, the memory proof and the like is used for playback in CAV-W mode. In this mode, the LRCK output conforms not to the crystal but to the VCO. Therefore, synchronization is frequently lost. By setting SYCOF of address 9 to 1, the synchronization loss of the LRCKI input is ignored and the playback can be simply performed. However, the playback is not perfect because the pre-value hold or data skip is occurred for the LRCKI input wow flatter. * Set SYCOF to 0 in all cases except for the playback with LRCK directly connected to LRCKI, PCMD to PCMDI and BCK to BCK in CAV-W mode. * Set SYCOF to 0 in advance when LRCK resynchronization is applied with LRWO = 0. Digital Bass Boost Bass boost without the external parts is possible by the built-in digital filter. The strength of boost has 2 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.
