Disk equalizer output terminal.
(PWM carrier = 88.2 kHz for DSP, Synchronize to PXO)
Analog double reference voltage supply terminal.
APC circuit ON/OFF indication signal output terminal.
At the laser on time, UHF = L at “HiZ” level and UHF = H at
“H” level.
Extemal flag output terminal for internal signal.
Can select signal from TEZC, FOON , FOK and RFZC by
command.
Extemal flag output terminal for internal signal.
Can select signal from DFCT , FOON , FMON and RFZC
by command.
Extemal flag output terminal for internal signal.
Can select signal from TRON , TRSR , FOK and SRCH
by command.
Extemal flag output terminal for internal signal.
Can select signal from TRON , DMON , HYS and SHC
by command.
Digital power supply voltage terminal.
Digital GND terminal.
General I/O terminal. Can change over input port or output
port by command. At the input mode time can readout a
state of terminal (H/L) by read command. At the output mode
time can control a state of terminal (H/L/HiZ) by command.
This terminal controls IO0~IO3 terminal.
At “L” level time, IO0, 1 out feed equalizer signal of 2-state
PWM, IO2, 3 out disk equalizer signal of 2-state PWM.
Normally, keep at open.
