RSYNC
Receive synchronizing signal input.
The eight bits PCM data required are selected from serial PCM signals on the DIN1 and DIN2
pins by the receive synchronizing signal.
Signals in the receive section are synchronized by this synchronizing signal. This signal must be
synchronized in phase with the BCLK (generated from the same clock source as BCLK). The
frequency should be 8 kHz 50 ppm to guarantee the AC characteristics which are mainly the
frequency characteristic of the receive section.
However, if the frequency characteristic of the system used is not strictly specified, this device
can operate in the range of 6 kHz to 9 kHz, but the electrical characteristics in this specifications
are not guaranteed.
XSYNC
Transmit synchronizing signal input.
The PCM output signal from the DOUT1 and DOUT2 pins is output in synchronization with this
transmit synchronizing signal. This synchronizing signal triggers the PLL and synchronizes all
timing signals of the transmit section.
This synchronizing signal must be synchronized in phase with BCLK.
The frequency should be 8 kHz 50 ppm to guarantee the AC characteristics which are mainly
the frequency characteristic of the transmit section.
However, if the frequency characteristic of the system used is not strictly specified, this device
can operate in the range of 6 kHz to 9 kHz, but the electrical characteristics in this specification
are not guaranteed.
Setting this signal to logic "1" or "0" drives both transmit and receive circuits to power saving
state.
