Functionality
(CH1 = Channel 1, CH2 = Channel 2)
This pin is used to bypass the signal ground. It needs to be decoupled to V
through a 0.1 μF ceramic decoupling capacitor. No external loads should be
tied to this pin.
CH2 Non-Inverting output of the receive smoothing filter. This pin can typically
drive a 600 Ω load (W682510) or 1200 Ω load (W682310).
CH1 Non-Inverting output of the receive smoothing filter. This pin can typically
drive a 600 Ω load (W682510) or 1200 Ω load (W682310)..

Power supply. This pin should be decoupled to V
capacitor.
This is the digital supply ground. This pin should be connected to 0V.
8 kHz Frame Sync input for the PCM receive section. It can also be connected
to the FST pin when transmit and receive are synchronous operations.
CH2 PCM input data receive pin. The data needs to be synchronous with the
FSR and BCLK pins.
CH1 PCM input data receive pin. The data needs to be synchronous with the
FSR and BCLK pins.
CH1 PCM output data transmit pin. The output data is synchronous with the
FST and BCLK pins.
CH2 PCM output data transmit pin. The output data is synchronous with the
FST and BCLK pins.
8 kHz transmit frame sync input. This pin synchronizes the transmit data bytes.
PCM transmit and receive bit clock input pin for CH1 and CH2 transmit.
This is the analog supply ground. This pin should be connected to 0V.
Compander mode select pin. μ-Law companding is selected when this pin is
LOW (tied to V
