Contents
FSW = low, MON = high, MDS = Z; MDP = servo control signal,
carrier frequency of 230Hz at TB = 0, and 460Hz at TB = 1.

CLVP mode
FSW = Z, MON = high; MDS = speed control signal, carrier frequency of
7.35kHz; MDP = phase control signal, carrier frequency of 1.8kHz.
MDS = PWM polarity signal, carrier frequency of
When DCLV
132kHz.
PWM and MD = 1 MDP = PWM absolute value output (binary),
carrier frequency of 132kHz.
DCLV on/off = 1
(FSW, MON not
required)
During CLVS
and CLVP modes
MDS = Z
When DCLV
MDP = ternary PWM output, carrier frequency
PWM and MD = 0
of 132kHz.
When DCLV on/off = 1 for the Digital CLV servo, the sampling frequency of the internal digital filter switches
simultaneously with the CLVP/CLVS switching.
Therefore, the cut-off frequency for the CLVS is fc = 70Hz when TB = 0, and fc = 140Hz when TB = 1.
Command bit
DSPB = 0
Processing
Normal-speed playback, C2 error correction quadruple correction, variable pitch possible.
Double-speed playback, C2 error correction double correction, variable pitch prohibited.
DSPB = 1
FLFC is normally 0.
