Notes) • The 64-bit slot is a LSB first, two's complement output. The 48-bit slot 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.
• XPLCK 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 protection timing match. (See $348.)
• RFCK is derived from the crystal accuracy, and has a cycle of 136µs. (during normal speed)
• C2PO represents the data error status.
• XRAOF is generated when the 32K RAM exceeds the ±28F jitter margin.

Description of SENS Signals
SENS output
Z
The SENS pin is high impedance.
XBUSY
Low while the auto sequencer is in operation, high when 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.
COMP
Counts the number of tracks set with Reg.B.
High when Reg.B is latched, low when the initial Reg.B number is input by CNIN.
COUT
Counts the number of tracks set with Reg.B.
High when Reg.B is latched, toggles each time the Reg.B number is input by CNIN. While $44
and $45 are being executed, toggles with each CNIN 8-count instead of the Reg.B number.
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 is executed, to set M when an M-track move is
executed and to set the jump count when fine search is executed for auto sequencer.
• 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.
• When the track jump count is from 0 to 15, the COUT signal is counted for 2N-track jumps and M-track
moves; when the count is 16 or over, the MIRR signal is counted. For fine search, the COUT signal is
counted.

Description of level meter mode (see Timing Chart 1-4.)
• When the LSI is set to this mode, it performs digital level meter functions.
• When the 96-bit clock is input to SQCK, 96 bits of data are output to SQSO.
The initial 80 bits are Sub-Q data (see "[2] Subcode Interface"). The last 16 bits are LSB first, which are 15bit PCM data (absolute values) and an L/R flag.
The L/R flag is high when the 15-bit PCM data is from the left channel and low when the data is from the right
channel.
• The PCM data is reset and the L/R flag is reversed after one readout.
Then maximum value measuring continues until the next readout.

Description of peak meter mode (see 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 value is set in the LSI internal
register again.
In other words, the PCM maximum value detection register is not reset 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 (– ∞) for this mode.

At this time, the readout clock is input to the SCLK pin.

[2] 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.
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. 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. 2-2 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 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 after SCOR is output, 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 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 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.
• The previously mentioned peak detection register can be connected to the shift-in of the 80-bit parallel/serial
register.
For ring control 1, input and output are shorted during peak meter and level meter modes.
For ring control 2, input and output are shorted during 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 Timing Chart 2-3.)
• The high and low intervals for SQCK should be between 750ns and 120µs.

[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 CXD2510Q, and operation is the same as for conventional control (however,
variable pitch cannot be used). 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 from the VCO to the
VCKI pin.)
When starting to rotate the 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 $E665X to set CAV-W mode and kick the disc,
then send $E60CX 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 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
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 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 $E665X command and
controlling VP0 to 7 with the $DX commands allows the rotational velocity to be varied from low speed to ×32
speed. (See "$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. The reference frequency for the velocity
measurement is a signal of 132.3kHz obtained by dividing XTAL (XTLI, XTLO) (384Fs) by 128. The velocity is
obtained by counting half of V16M pulses while the reference is high, and the result is output from the new
CPU interface as 10 bits (VF0 to 10). 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.

§ 3-4. VCO-C Mode
This is VCO control mode. In this mode, the V16M oscillation frequency can be controlled by setting $D
commands VP0 to 7 and VPCTL0, 1. The V16M oscillation frequency can be expressed by the following
equation.
V16M =
1 (256 – n)

n: VP0 to 7 setting value

The VCO1 oscillation frequency is determined by V16M. The VCO1 frequency can be expressed by the
following equation.

[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 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. 4-1.
The CXD3011R-1 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 regenerates 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.
• The digital PLL in CLV-N mode has a secondary loop, and is controlled by the primary loop (phase) 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 cases, turning the secondary loop off yields
better playability. However, in this case the capture range becomes ±50kHz.
• 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.

§ 4-2. 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 CXD3011R, 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 set to 12∗, 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 12 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.
∗ Default values. These values can be set as desired by $C commands SFP0 to 3 and SRP0 to 3.
§ 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 CXD3011R-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 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.

§ 4-4. DA Interface Output
• The CXD3011R-1 has two DA interface output modes.
a) 48-bit slot interface output
This interface includes 48 cycles of the bit clock within one LRCK cycle, and is MSB first.
When LRCK is high, the data is for the left channel.
b) 64-bit slot interface output
This interface includes 64 cycles of the bit clock within one LRCK cycle, and is LSB first.
When LRCK is low, the data is for the left channel.
However, the DA output for the 64-bit slot supports 16× speed.

§ 4-5. Digital Out
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 CXD3011R-1 supports type 2 form 1.
This LSI supports 2 kinds of Digital Out generation methods; one is to generate the Digital Out using the PCM
data read out from the disc and the other is to generate it using the DA interface input (PCMDI, LRCKI and
BCKI).
§ 4-5-1. Digital Out From PCM Data
The Digital Out is generated from the PCM data which is read out from the disc.
The clock accuracy of the channel status is automatically set to level II when the crystal clock is used and to
level III in CAV-W mode. In addition, the Sub Q data matched twice continuously with CRC check are input to
the initial 4 bits (bits 0 to 3).
DOUT is output when the crystal is 34MHz and XTSL is high in CLV-N or CLV-W mode with DSPB = 1.
Therefore, DOUT is set to off by making MD2 pin to 0.

Digital Audio Data Input
The input signal of the digital audio data is input from the DAC input pins PCMDI, LRCKI and BCKI. The input
format supports 32-bit slot/LSB first, 64-bit slot/LSB first and 48-bit slot/MSB first. The input format can be
selected by $34A command MLSL.
∗ DAC supports only 48-bit slot input. In MLSL=0, therefore, DAC should be forcibly muted.
1) MLSL = 0
32-bit slot/LSB first, 64-bit slot/LSB first
(The DAC output requires the forcible muting.)
2) MLSL = 1
48-bit slot/MSB first
(The DAC output is possible at the same time.)
Mute Function
By setting the command bit DOUT_DMUT to 1, all the audio data portions in the Digital Out output can be
made to 0 with the Channel Status Data as it is.
Input/Output Synchronization Circuit
In the normal operation, the DAC automatically synchronizes with the input LRCK. However, when the input
data has much jitter or the power is turned on the synchronization may not be achieved. In such a case, the
internal operation should be forcibly synchronized by setting $34A DOUT WOD to 1. Also, the forcible
synchronization is required when the operating frequency is changed such as switching between CLV and
CAV,etc. Be sure to set DOUT WOD to 0 before performing forcible synchronization again.
∗ When the synchronization is performed, the internal counter which counts the frames is cleared so that the
frame is started from 0 after the synchronization processed. In case where the automatic processing of the
synchronization is not desirable or the user wants to do it manually, set the command $34A WIN EN to 0 to
invalidate the automatic synchronization circuit.
Clock System of DOUT Circuit
For the DOUT block, the master clock is set using the clock control command MCSL ($A) employed by the
DAC block. Set MCSL to 1 for 768fs and to 0 for 384fs.

§ 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 jump, fine search and M-track move
are executed automatically.
The servo block operates according to the built-in program during the auto sequence execution (when
XBUSY = low), so that does not accept commands from the CPU, that is $0, 1 and 2 commands. ($3 to E
commands are accepted.)
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
100µs 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 into 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 [1] "$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 the focus, tracking, and sled
servos 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 with register 5), the tracking and sled servos are turned on.
– 92 –
CXD3011R-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 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 when N is less than 16, and MIRR is used with 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 with 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 that a higher precision is achieved
by controlling the traverse speed, and a longer distance jump is achieved by controlling the sled. The track
jump count is set with register 7. N can be set to 216 tracks. After kicking the actuator and sled, the traverse
speed is controlled based on the overflow G. Set kick D and F with register 6 and overflow G with register 5.
Also, sled speed control during traverse can be turned off by causing COMP to fall. Set the number of
tracks which COMP falls with 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 with 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 – α for the traverse monitor counter which is set with 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 216 tracks. Like the 2N-track jump, 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 by moving only the sled, and is therefore suited for moving across several thousand to several
ten-thousand tracks. In addition, the track and sled servos are turned off after M tracks have been counted
through COUT or MIRR unlike for the other jumps. Transfer $25 from the microcomputer after the actuator
has stabilized.

§ 4-9. DAC Block Playback Speed
The operating speed of the DAC block is determined by the crystal and the $AX command MCSL regardless of
the operating conditions of the CD-DSP block. This allows the DAC block and DSP block playback modes to
be set independently.

§ 4-10. DAC Block Input Timing
The DAC input timing chart is shown below.
Audio data is not transferred from the CD signal processor block to the DAC block inside the CXD3011R. This
enables to send data to the DAC block via the external audio DSP, etc.
When the data is input to the DAC block without using the audio DSP, the data must be connected outside the
LSI. In this case, LRCK, BCK and PCMD can be connected directly with LRCKI, BCKI and PCMDI. (See the
Application Circuit.)

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" has continued for about 300ms (16384/44.1kHz), zero data is detected. Zero data detection is
performed independently for the left and right channels.
Mute flag output
The LMUTO and RMUTO pins go active when any one of the following conditions is met.
The polarity can be selected by the $9X command ZDPL.
• When zero data is detected
• When the $9X commands DAC SMUTL and DAC SMUTR are set (The flags change independently for the
left and right channels.)
The mute flag output at initializing is as shown below. (This is in the case the zero data is input from LRCKI,
BCKI, PCMDI and the time address $9X command ZDPL and address $AX command MCSL stay in the
initial values.)

Attenuation operation
Assuming the attenuation commands X1, X2 and X3, the corresponding audio outputs are Y1, Y2 and Y3 (Y1
> Y3 > Y2). First, the command X1 is sent and then the audio output approaches Y1. When the command
X2 is sent before the audio output reaches Y1 (A in the figure), the audio output passes Y1 and approaches
Y2. And, when the command X3 is sent before the audio output rteaches Y2 (B or C in the figure), the audio
output approaches Y3 from the value (B or C in the figure) at that point.

Forced mute
Forced mute results when the $AX command FMUT is set to 1.
Forced mute fixes the PWM output. (Low for left channel, high for right channel)
Zero detection mute
Setting $9X command ZMUT to 1 enables forced mute, when zero data is detected for both the left and
right channels. (See "Zero data detection".)
LRCK Synchronization
Synchronization is performed at the first rising edge of the LRCK input when reset.
After that, synchronization is lost when the LRCK input frequency changes, etc., so 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 $9X command DSPB setting changes
• When the $9X command MCSL setting changes
• When operation switches between CLV mode and CAV mode
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 these cases as well.
For resynchronization, set the $9X command XWOC to 0 or the external pin XWO to low, wait for one
LRCK cycle or more, and then set XWOC to 1 and XWO to high.
∗ When setting XWOC to 0 or the external pin XWO to low, be sure to set the $9X command SYCOF to 0
beforehand.
– 104 –
CXD3011R-1
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 the LRCK's asynchronization, facilitating playback. However, the
playback is not perfect because pre-value hold or data skip occurs due to the wow and flutter in the LRCKI
input.
∗ Set SYCOF to 0 other than when connecting LRCK, PCMD and BCK directly with LRCKI, PCMDI and
BCKI, respectively, and performing playback in CAV-W mode.
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.
The bass boost is set using BSBST and BBSL of address A.

§ 5-2. Digital Servo Block Master Clock (MCK)
The FSTIO pin is the clock input/output pin for the servo block. At preset, the clock with 2/3 frequency of the
crystal is internally supplied to the servo block and the FSTIO pin serves as the monitor output pin for it. To
make this pin act as the input pin, set the command $8X command FSTIN to 1.
The master clock (MCK) is generated by dividing the frequency of the FSTIO pin. The frequency division ratio
is 1, 1/2 or 1/4.
Table 5-1 below assumes the preset status (where the clock with 2/3 frequency of the crystal is internally
supplied to the servo).
XT4D and XT2D are for the $3F command and XT1D is for the $3E command. (Default = 0)
The digital servo block is designed with an MCK frequency of 5.6448MHz (128Fs) as typical.

§ 5-3. DC Offset Cancel [AVRG (Average) Measurement and Compensation] (See Fig. 5-3.)
The CXD3011R-1 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 CXD3011R, 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 of 256
samples, and then loads these values into each AVRG register.
The AVRG measurement commands are VCLM, FLM, RFLM and 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 5-2.)
Monitoring requires that the upper 8 bits of the command register are 38 (Hex).

§ 5-4. E:F Balance Adjustment Function (See Fig. 5-3.)
When the disc is rotated with the laser on, and with the FCS (focus) servo on via FCS Search (focus 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. 5-3.)
§ 5-5. 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. 5-3.)
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 SOCT1, SOCT0. (See "DSP Block
Timing Chart".)
The FBIAS register can be used as a counter by setting D13 (FBSS) of $3A to 1. The FBIAS register functions
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 D10 (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 command register are $3A at this time, SENS
goes to high and the counter stop can be monitored.
A

C
FBIAS setting value (FB9 to 1)
LIMIT value (FBL9 to 1)
Here, assume the FBIAS setting value FB9 to 1
and the FBIAS LIMIT value FBL9 to 1 are 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 counts at 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 1/512 × VDD/2.

§ 5-6. 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 (Hex), the completion of AGCNTL operation can be confirmed by monitoring the
SENS pin. (See Timing Chart 5-4 and "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.

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

These coefficients change from 01 to 7F (Hex), 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.

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.
– 113 –
CXD3011R-1
AGCNTL and default operation have 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 CXD3011R-1 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. 5-5.

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 CXD3011R-1 has 2 types of gain-up filter structures in TRK gain-up mode which can be selected by
setting D16 of $1. (See Table 5-17.)
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× magnification set using D17 and D16 when D18 = D19 = 0 is set with
$3. (See Table 5-10.)
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.

§ 5-9. 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. 5-11.)
The bottom hold speed and mirror sensitivity can be selected from 4 values using D7 and D6, and D5 and D4,
respectively, of $3C.

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. 5-12.)
The DFCT comparator level can be selected from four values using D13 and D12 of $3B.

§ 5-10. 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, these operations are 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. 5-13.)
In addition, these operations are activated by the default. They can be disabled by setting D7 (DFSW) of
$38 to 1.

§ 5-11. 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. 5-14.)
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 5-17.)
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 8 bits of the command register are $1, vibration detection can be monitored from the SENS pin.

§ 5-12. 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. 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. (See Fig. 5-17.)
In addition, the low frequency for the tracking drive after masking can be boosted. (SFBK1, 2 of $34B)

§ 5-13. 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.
§ 5-14. Serial Readout Circuit

§ 5-15. Writing to 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 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 data. Coefficient rewriting is completed 11.3µs (when MCK = 128Fs) after the command is
received. When rewriting multiple coefficients, be sure to wait 11.3µs (when MCK = 128Fs) before sending the
next rewrite command.

§ 5-17. Servo Status Changes Produced by the 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.

These commands turn on the boost function. (See "§ 5-20. Filter Composition".)
There are five boosters (three for the TRK filter and two for the FCS filter) which can be turned on and off
independently.
THBON: When 1, the high frequency is boosted for the TRK filter. Preset when 0.
FHBON: When 1, the high frequency is boosted for the FCS filter. Preset when 0.

TLB2ON: When 1, the low frequency is boosted for the TRK filter. Preset when 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.
Set SFJP ($36) to 1 or TAOZ ($34D) to 0 in order to boost the low frequency for the TRK jump operation.

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 § 5-13.
CETZ:
The input from the TE pin normally 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.

BTS1, BTS0: This sets 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. This is valid only when BTF of $3B is 0.
MRC1, MRC0: This sets the minimum pulse width for masking the MIRR signal of the MIRR generation circuit.
As noted in § 5-9, 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. This sets 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, creating a difference 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 the 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, creating a difference 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.

• Input coefficient sign inversion when SFID = 1 and THID = 1
The preset coefficients for the TRK filter are negative for input and positive for output. With this, CXD3011R-1
outputs servo drives which are reversed phase of input errors.

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 60h.)
For the same reason, when THID = 1, the TRK hold input coefficient (K40) sign must be inverted.
