AC-LINK DIGITAL SERIAL INTERFACE PROTOCOL
The WM9708 incorporates a 5-pin digital serial interface that links it to the AC
’
97 controller. The AC-
link is a bi-directional, fixed rate, serial PCM digital stream. It handles multiple input and output audio
streams, as well as control Register accesses, employing a time division multiplexed (TDM) scheme.
The AC-link architecture divides each audio frame into 12 outgoing and 12 incoming data streams,
each with 20-bit sample resolution and a 16-bit header slot. With a minimum required DAC and ADC
resolution of 16-bits, AC
’
97 may also be implemented with 18 or 20-bit DAC/ADC resolution, given
the headroom that the AC-link architecture provides. The WM9708 provides support for 18-bit
operation.
