I/O
Function
I
Master clock input pin. Used for input of 256-fs clock (duty: 40 to 60%).
O
Serial interface’s frame sync clock output pin.
Used for L channel data I/O when LRCLK = low level
Used for R channel data I/O when LRCLK = high level
O
Serial interface’s bit sync clock output pin.
Used for I/O of audio data from SI and SO in sync with BCLK. BCLK is
generated on-chip as MCLK divided by eight.
I
Serial interface’s data input pin. Used for serial input (synchronized with
BCLK) of audio data (two’s complement, MSB first).
—
No connection
O
Serial interface’s data output pin. Used for serial output (synchronized with
BCLK) of audio data (two’s complement, MSB first).
—
Digital power supply pin. Used for input voltage range of +3 to +5.5 V.
—
No connection
G
Digital ground pins.
I/O
Parallel data I/O pins. Used for input/output of address data and volume
setting data.
—
No connection
O
R-channel DAC output pin. When this pin is used, the R-channel DAC output
can be monitored without attenuation regardless of the volume setting.
O
R-channel analog audio output pin.
O
L-channel DAC output pin. When this pin is used, the L-channel DAC output
can be monitored without attenuation regardless of the volume setting.
O
L-channel analog audio output pin.
G
Analog ground pins.
—
Analog power supply pin. Used for input voltage range of +3 to +5.5 V.
—
No connection
