$9X commands

Command bit

DCLV on/off = 0

In CLVS mode

FSW = low, MON = high, MDS = Z; MDP = servo control signal,

carrier frequency of 230Hz at TB = 0 and 460Hz at TB = 1.

FSW = Z, MON = high; MDS = speed control signal, carrier frequency of

7.35kHz; MDP = phase control signal, carrier frequency of 1.8kHz.

When DCLV PWM

and MD = 1

(Prohibited in CLV-W

and CAV-W modes)

MDS = PWM polarity signal, carrier frequency

of 132kHz

MDP = PWM absolute value output (binary),

carrier frequency of 132kHz

When DCLV PWM

and MD = 0

MDS = Z

MDP = ternary PWM output, carrier frequency

of 132kHz

In CLVP mode

In CLVS and

CLVP modes

DCLV on/off = 1

(FSW, MON not

required)

CLV mode

Contents

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

DSPB = 1

Normal-speed playback, C2 error quadruple correction.

Double-speed playback, C2 error double correction. (quadruple correction when ERC4 = 1)

Processing

FLFC is normally 0.

FLFC is 1 in CAV-W mode, for any playback speed.

Command bit

DPLL = 0 ∗

DPLL = 1

RFPLL is analog. PDO, VCOI and VCOO are used.

RFPLL is digital. PDO is high impedance.

BiliGL MAIN = 0

BiliGL MAIN = 1

Definition of bilingual capable MAIN, SUB and STEREO

The left channel input is output to the left and right channels for MAIN.

The right channel input is output to the left and right channels for SUB.

The left and right channel inputs are output to the left and right channels for STEREO.

∗ External parts for the FILI, FILO and PCO pins are required even when analog PLL is selected.
