Description
Focus OK input. Used for SENS output and the servo auto sequencer.
Spindle motor on/off control output.
Spindle motor servo control.
Spindle motor servo control.
GFS is sampled at 460Hz; when GFS is high, this pin outputs a high signal.
If GFS is low eight consecutive samples, this pin outputs low.
TEST pin. Normally GND.
Master PLL (slave = digital PLL) filter output.
Master PLL filter input.
Master PLL charge pump output.
GND.
Analog GND.
Master VCO control voltage input.
Analog power supply (+5V).
EFM signal input.
Constant current input of asymmetry circuit.
Asymmetry comparator voltage input.
EFM full-swing output (low = Vss, high = VDD).
Low: asymmetry circuit off; high: asymmetry circuit on.
D/A interface. Word clock f = 2Fs.
D/A interface. LR clock f = Fs.
D/A interface. Serial data (two's complement, MSB first).
D/A interface. Bit clock.
GTOP output.
XUGF output.
XPLCK output.
Power supply (+5V).
GFS output.
RFCK output.
C2PO output.
XRAOF output.
MNT3 output.
MNT1 output.
MNT0 output.
16.9344MHz crystal oscillation circuit input, or 33.8688MHz input.
16.9344MHz crystal oscillation circuit output.
Crystal selection input. Set low when the crystal is 16.9344MHz, high when 33.8688MHz.
