ac-link digital serial interface protocol
The TLV320AIC27 incorporates a five-pin digital serial interface that links it to the AC’97 controller. The ac link
is a bidirectional, 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.
With a minimum required resolution of 16-bits for the DAC and the ADC, AC’97 can also be implemented with
18 or 20-bit DAC/ADC resolution, given the headroom that the ac-link architecture provides. The TLV320AIC27
provides support for 18-bit operation.
