Notes) • PCMD is a MSB first, two's complement output.
• GTOP is used to monitor the frame sync protection status. (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.
• XPCK 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 timing match.
• RFCK is derived from the crystal accuracy, and has a cycle of 136µs.
• C2PO represents the data error status.
• XROF is generated when the 16K RAM exceeds the ±4F jitter margin.

Description of SENS Signals
SENS output
XBUSY
Low while the auto sequencer is in operation, high when the operation terminates.
FOK
Outputs the same signal as the FOK pin.
High for "focus OK".
GFS
High when the regenerated frame sync is obtained with the correct timing.
COUT
Counts the number of tracks with frequeny division ratio set by $B. High when $B is
latched, and toggles each time COUT is counted just for the frequency diviison ratio set
by $B.
OV64
Low when the EFM signal is lengthened by 64 channel clock pulses or more after passing
through the sync detection filter.

This command is used to set N when a 2N-track jump and an N-track move are executed for auto sequence.
• The maximum track count is 65,535, but note that with a 2N-track jump the maximum track jump count
depends on the mechanical limitations of the optical system.
• The number of tracks jumped is counted according to the COUT signals.

Setting the SOCT command of $8X to 0 and the SL1 and SL0 commands of $BX to 0 and 1, respectively,
results in peak detection mode. The SQSO output is connected to the peak register. The maximum PCM data
values (absolute value, upper 8bits) for the left and right channels can be read from SQSO by inputting 16
clocks to SQCK. Peak detection is not performed during SQCK input, and the peak register does not change
during readout. This SQCK input judgment uses a retriggerable monostable multivibrator with a time constant
of 270µs to 400µs. The time during which SQCK input is high should be 270µs or less. Also, peak detection is
restarted 270µs to 400µs after SQCK input.
The peak register is reset with each readout (16 clocks input to SQCK).
The maximum value in peak detection mode is detected and held in this status until the next readout. When
switching to peak detection mode, readout should be performed one time initially to reset the peak register.
Peak detection can also be performed for previous value hold and average value interpolation data.

§2. Subcode Interface
In the CXD3017Q, only SubQ can be readout.
The subcodes P and R to W cannot be readout.
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. 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, 80 bits are
loaded into the parallel/serial register.
When SQSO goes high 400µs (monostable multivibrator time constant) or more after subcode readout, the
CPU determines that the new data (which passed the CRC check) has been loaded.
• The CRCF reset is performed by inputting SQCK. When the subcode data is discontinuous after track jump,
etc. CRCF is reset by inputting SQCK. Then, if CRCF =1, the CPU determines that the new data 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 400µs. 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 120µs.

§3. Description of Other Functions
§3-1. 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. 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.

§3-2. Frame Sync Protection
• In normal-speed playback, a frame sync is recorded approximately every 136µs (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.
§3-3. 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.

There are three Digital Out: 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 CXD3017Q 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.

§3-6. 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 and N-track move are executed
automatically.
The commands which enable transfer to the CXD3017Q during the execution of auto sequence are $4X to
$EX.
When CLOK goes from low to high while XBUSY is low, XBUSY does not become high for a maximum of
100µs after that point.

CXD3017Q
(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. 3-6. 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 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 216 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 216 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.

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" has continued about for 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 go active when any one of the following conditions is met.
The polarity can be selected with the ZDPL command of $9X.
• When zero data is detected
• When a high signal is input to the SYSM pin
• When the SMUT command of $AX is set
Attenuation operation
Assuming attenuation data X1, X2 and X3 (X1 > X3 > X2), the corresponding audio outputs are Y1, Y2 and
Y3 (Y1 > Y3 > Y2). First, X1 is sent, followed by X2. If X2 is sent before X1 reaches Y1 (A in the figure), X1
continues approaching Y2. Next, if X3 is sent before X1 reaches Y2 (B or C in the figure), X1 then
approaches Y3 from the value (B or C in the figure) at that point.

When the ZMUT command of $9X is set to 1 and the zero data is detected for the left or right channel, the
analog mute is applied to the each channel.
(See "Zero data detection".)
When the ZMUT command of $9X is set to 1, the analog mute is applied even if the mute flag output condition
is met. When the zero detection mute is on, set the DCOF command of $9X to 1.

LRCK Synchronization
Synchronization is performed at the first falling edge of the LRCK input during reset.
After that, synchronization is lost when the LRCK input frequency changes and 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 DSPB command of $9X setting changes
• When the MCSL command of $9X setting changes
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 this case as well.
For resynchronization, set the LRWO command of $AX to 1, wait for one LRCK cycle or more, and then set
LRWO to 0.
∗ When setting LRWO, set OPSL2 to 1. (See the $AX commands.)
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 3-12 for the digital bass boost frequency response.

§3-11. LPF Block
The CXD3017Q contains an initial-stage secondary active LPF with numerous resistors and capacitors and an
operational amplifier with reference voltage.
The resistors and capacitors are attached externally, allowing the cut-off frequency fc to be determined flexibly.
The reference voltage (VC) is (AVDD – AVSS) × 0.45.
The LPF block application circuit is shown below.
In this circuit, the cut-off frequency is fc ≈ 40kHz.

§3-13. CD TEXT Data Demodulation
• In order to demodulate the CD TEXT data, set the command $8 Data 6 D3 TXON to 1.
It requires 26.7ms (max.) to demodulate the CD TEXT data correctly after TXON is set to 1.
• The CD TEXT data is output by switching the SQSO pin with the command. The CD TEXT data output is
enabled by setting the command $8 Data 6 D2 TXOUT to 1. To read data, the readout clock should be input
to SQCK.
• The readable data are the CRC counting results for the each pack and the CD TEXT data (16 bytes) except
for CRC data.
• When the CD TEXT data is read, 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.
• Data which can be stored in the LSI is 1 packet (4 packs).

§4-3. DC Offset Cancel [AVRG (Average) Measurement and Compensation] (See Fig. 4-3.)
The CXD3017Q can measure the averages of RFDC, VC, FE and TE and compensate these signals using the
measurement results to control the servo effectively. This AVRG measurement and compensation is
necessary to initialize the CXD3017Q, and is able to cancel the DC offset.
AVRG measurement takes the levels applied to the VC, FE, RFDC and TE pins as the digital average values
of 256 samples, and then loads these values into each AVRG register.
The AVRG measurement commands are D15 (VCLM), D13 (FLM), D11 (RFLM) and D4 (TLM) of $38.
Measurement is on when the respective command is set to 1.
AVRG measurement requires approximately 2.9ms to 5.8ms (when MCK = 128Fs) after the command is received.
The completion of AVRG measurement operation can be monitored by the SENS pin. (See Timing Chart 4-2.)
Monitoring requires that the upper 8 bits of the command register are 38 (h).

§4-4. E:F Balance Adjustment Function (See Fig. 4-3.)
When the disc is rotated with the laser on, and with the FCS (focus) servo on via FCS 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. 4-3.)
§4-5. 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. 4-3.)
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 SOCT to 1. (See "DSP Block Timing
Chart".)

§4-6. 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 (h), the completion of AGCNTL operation can be confirmed by monitoring the
SENS pin. (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.

Coefficient K13 changes for AGF (focus AGCNTL) and coefficients K23 and K07 change for AGT (tracking

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).

The following settings can be changed with $35, $36 and $37.

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.
– 74 –
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.

TRK Servo
The TRK JUMP (track jump) level can be set with 6 bits (D13 to D8) of $36.
In addition, when the TRK servo is on and D17 of $1 is set to 1, the TRK servo filter switches to gain-up mode.
The filter also switches to gain-up mode when the LOCK signal goes low or when vibration is detected with the
anti-shock circuit (described hereafter) enabled.
The CXD3017Q has 2 types of gain-up filter structures in TRK gain-up mode which can be selected by setting
D16 of $1. (See Table 4-17.)
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× set using D17 and D16 when D18 = D19 = 0 is set with $3. (See
Table 4-10.)
SLD MOV must be performed continuously for 50µs 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.

§4-9. MIRR and DFCT Signal Generation
The RF signal obtained from the RFDC pin is sampled at approximately 1.4MHz (when MCK = 128Fs) 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 this envelope waveform.
The MIRR signal is generated by comparing the waveform generated by subtracting the bottom hold value
from the peak hold value with this MIRR comparator level. (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.

§4-10. 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, this operation is 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. 4-13.)
In addition, these operations are activated by the default. They can be disabled by setting D7 (DFSW) of $38 to 1.

§4-11. 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. 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.

§4-12. 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. (SFBK1, 2 of $34B)

§4-13. 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.
§4-14. Serial Readout Circuit
The following measurement and adjustment results specified beforehand by serial command $39 can be read

§4-15. Writing to 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 40µs (when MCK = 128Fs) 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 the data. Coefficient rewriting is completed 11.3µs (when MCK = 128Fs) after the command is
received. When rewriting multiple coefficients continuously, be sure to wait 11.3µs (when MCK = 128Fs)
before sending the next rewrite command.
§4-16. PWM Output
FCS, TRK and SLD PWM format outputs are described below.
In particular, FCS and TRK use a double oversampling noise shaper.
Timing Chart 4-20 and Fig. 4-21 show examples of output waveforms and drive circuits.

§4-17. 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.

When 1, the high frequency is boosted for the TRK filter. Preset is 0.
When 1, the high frequency is boosted for the FCS filter. Preset is 0.
When 1, the low frequency is boosted for the TRK filter. Preset is 0.
When 1, the low frequency is boosted for the FCS filter. Preset is 0.
When 1, the low frequency is boosted for the TRK filter. Preset is 0.
The difference between TLB1ON and TLB2ON is the position where the low frequency is boosted.
For TLB1ON, the low frequency is boosted before the TRK jump, and for TLB2ON, after the TRK jump.
The following commands set the boosters. (See §4-20. Filter Composition.)

When 1, the DFCT signal described in §4-9 and the new DFCT signal are switched and output
from the DFCT pin.
The switching timing is as follows.
When the §4-9 DFCT signal is low, the new DFCT signal is output from the DFCT pin.
When the §4-9 DFCT signal is high, this DFCT signal is output from the DFCT pin.
In addition, the time at which the new DFCT signal can be output after the §4-9 DFCT signal
switches to low can also be set. (See IDFT1, 0 of $34E.)

STZC is the TZC generated by sampling the TE signal at 700kHz. (when MCK = 128Fs)
DTZC is the delayed phase STZC. (The delay time can be selected by D14 of $36.)
HPTZC is the fast phase TZC passed through a HPF with a cut-off frequency of 1kHz.
See §4-13.
CETZ:
Normally, the input from the TE pin enters the TRK filter and is used to generate the TZC
signal. However, the input from the CE pin can also be used. This function is for the center
error servo.
When 0, the TZC signal is generated by using the signal input to the TE pin.
When 1, the TZC signal is generated by using the signal input to the CE pin.
When 0, the signal input to the TE pin is input to the TRK servo filter.
When 1, the signal input to the CE pin is input to the TRK servo filter.
CETF:
These commands output the TZC signal.
COT2, COT1: The COUT signal is replaced by the TZC signal. Concretely, the TZC signal is output from the

The MIRR signal is replaced by the STZC signal. Concretely, the STZC signal is output from

signal.
These commands set the MIRR signal generation circuit.
BTS1, BTS0: These set the count-up speed for the bottom hold value of the MIRR generation circuit.
The time per step is approximately 708ns (when MCK = 128Fs). The preset value is BTS1 = 1,
BTS0 = 0 like the CXD2586R. These bits are valid only when BTF of $3B is 0.
MRC1, MRC0: These set the minimum pulse width for masking the MIRR signal of the MIRR generation circuit.
As noted in §4-9, the MIRR signal is generated by comparing the waveform obtained by
subtracting the bottom hold value from the peak hold value with the MIRR comparator level.
Strictly speaking, however, for MIRR to become high, these levels must be compared
continuously for a certain time. These bits set that time.
The preset value is MRC1 = 0, MRC0 = 0 like the CXD2586R.

SLED servo filter input can be obtained not from SLD in Reg, but from M0D, which is the TRK
filter second-stage output.
When the low frequency component of the tracking error signal obtained from the RF amplifier
is attenuated, the low frequency can be amplified and input to the SLD servo filter.
Only during TRK servo gain up2 operation, coefficient K30 is used instead of K00. Normally, the
DC gain between the TE input pin and M0D changes for TRK filter gain normal and gain up2,
and error occurs in the DC level at M0D. In this case, the DC level of the signal transmitted to
M00 can be kept uniform by adjusting the K30 value even during the above switching.
TRK hold filter input can be obtained not from SLD in Reg, but from M0D, which is the TRK
filter second-stage output.
When signals other than the tracking error signal from the RF amplifier are input to the SE input
pin, the signal transmitted from the TE pin can be obtained as TRK hold filter input.
Only during TRK servo gain up2 operation, coefficient K46 is used instead of K40. Normally, the
DC gain between the TE input pin and M0D changes for TRK filter gain normal and gain up2,
and error occurs in the DC level at M0D. In this case, the DC level of the signal transmitted to
M18 can be kept uniform by adjusting the K46 value even during the above switching.
∗ See "§4-20. Filter Composition" regarding the SFID, SFSK, THID and THSK commands.
The focus error (FE) and tracking error (TE) can be generated internally.
When 0, the FE and TE signal input mode results. Input each error signal through the FE and
TE pins. (default)
When 1, the FE and TE signal generation mode results and the FE and TE signals are generated
internally.
These turn on and off SLD filter correction independently of the TRK filter.

When SFID = 1, the TRK filter negative input coefficient is applied to the SLD filter, so the SLD input coefficient
(K00) sign must be inverted. (For example, inverting the sign for coefficient K00: E0h results in 20h.)
For the same reason, when THID = 1, the TRK hold input coefficient (K40) sign must be inverted.

FIFZB3 to FIFZB0:
This sets the slice level at which FZC changes from high to low.
FIFZA3 to FIFZA0:
This sets the slice level at which FZC changes from low to high.
The FIFZB3 to FIFZB0 and FIFZA3 to FIFZA0 setting values are valid only when $3A FIFZC is 1.
Set so that the FIFZB3 to FIFZB0 ≤ FIFZA3 to FIFZA0.
Hysteresis can be added to the slice level by setting FIFZB3 to FIFZB0 < FIFZA3 to FIFZA0.
FZC slice level =
FIFZB3 to FIFZB0 or FIFZA3 to FIFZA0 setting value
