Right channel N output
Right channel P output
Right channel power supply.
O
Right channel mute output
O Subcode block synchronization signal output
O C1 and C2 error correction state monitor
O Subcode P, Q, R, S, T, U, V, and W output
O Subcode frame synchronization signal output. Falls when the subcode output goes to the standby state.
I
Subcode readout clock input. This is a Schmitt input.
O Digital output
O Outputs a 7.35 kHz synchronization signal generated by dividing the crystal oscillator frequency.
O Subcode Q output standby output
I
Read/write control input
O Subcode Q output
I
Input for commands from the control microprocessor
I
Command input acquisition clock. Also used as the SQOUT subcode readout clock input. This is a Schmitt input.
I
