External PCM interface
PCMIN, PCMOUT, PCMCLK, PCMSYNC carry one channel of voice data using 8-bit A/u-law, 13-bit /14-bit/16-bit linear
PCM at 8kbps. PT8R1202 generates PCMCLK and PCMSYNC as both outputs or input, which can be programmed, and
interfaces directly to PCM audio devices. PCMSYNC operates at fixed clock frequency of 8KHz. PCMCLK operates at one of
two fixed clock frequencies such as 128 and 256kHz. PCM interface supports both long frame sync signal and short frame sync
signal. Additionally, PT8R1202 supports two or four channels of 8-bit A/u-law PCM interfacing with external multi-channel
codec.
