Function
Crystal oscillator ground. Must be connected to 0 V.
O
16.9344 MHz crystal oscillator connections. Use a 33.8688 MHz crystal oscillator for quad-speed playback.
I
Crystal oscillator power supply
Right channel ground. Must be connected to 0 V.

converter pins
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. This pin must be connected to 0 V if unused.
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
Chip reset input. This pin must be set low temporarily when power is first applied.
O Functions as the PCK frequency detection monitor output in VCEC mode.
O Output port
O 16.9344 MHz output. 33.8688 MHz output in 4 × playback mode
O 4.2336 MHz output
I
Test input. A pull-down resistor is built in. Must be connected to 0 V.
I
Chip select input. A pull-down resistor is built in. When control is not used, this pin must be connected to 0 V.
I
Defect detection signal input. Must be connected to 0 V if unused.
I
Variable pitch VCO control input. Must be connected to 0 V if unused.
Note: Of the general-purpose I/O ports, any unused input ports must be connected to 0 V, or set to be output ports.
