Function
High-level reference voltage
Normally connected through a capacitor to AGND.
High-level reference voltage input
Muting signal input
The soft muting function is turned on by a high input.
Standard/double-speed mode switching input
Double-speed operation when high, standard when low.
Bit clock input
Digital audio data input
Input is in a twos-complement MSB-first format.
LR clock input
CH1 is input when this pin is high, CH2 when low.
Digital system power supply
Clock output
In 392 fs mode: outputs a 196 fs clock
In other modes: outputs a clock with the XIN frequency
Crystal oscillator output (system clock output)
Crystal oscillator input (system clock input)
Digital system ground
Initialization signal input
The LSI is initialized when this pin is set low.
De-emphasis filter on/off switching
The filter is turned on when this pin is set high, off when set low.
De-emphasis filter mode (32, 44.1, or 48 kHz) selection
