Description
O 1, 0 Focus drive output.
Digital power supply.
O 1, 0 Track count signal output.
O
1, 0
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.
O 1, 0 Spindle motor servo control output.
O 1, 0 Spindle motor servo control output.
I
Disc innermost track detection signal input.
O 1, 0 2/3-frequency division output for Pins 103 and 104.
I
Digital servo reference clock input.
I
Crystal selection input. Low when the crystal is 16.9344MHz; high when the
crystal is 33.8688MHz.
O 1, 0 4.2336MHz output.
O 1, 0 D/A interface. Word clock f = 2Fs
Digital power supply.
O 1, 0 D/A interface. LR clock f = Fs
I
LR clock input to DAC (48-bit slot).
O 1, 0 D/A interface. Serial data. (two's complement, MSB first)
I
Audio data input to DAC (48-bit slot).
O 1, 0 D/A interface. Bit clock.
I
Bit clock input to DAC (48-bit slot).
O
1, 0
Outputs a high signal when the playback disc has emphasis, and a low
signal when there is no emphasis.
I
