8.3 Digital interface
8.3.1
AC-link digital serial interface protocol
The UCB1400 incorporates a 5-pin digital serial interface that links it to the AC ’97
Controller. AC-link is a bi-directional, fixed rate, serial PCM digital stream. It handles
multiple input, and output audio and modem 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. The control and data slots defined by
UCB1400 include:
SDATA_OUT TAG (output slot 0)
SDATA_IN TAG (input slot 0)
Control (CMD ADDR & DATA) write port (output slots 1, 2)
Status (STATUS ADDR & DATA) read port (input slots 1, 2)
PCM L & R DAC playback (output slots 3, 4)
PCM L & R ADC record (input slots 3, 4)
GPIO interrupt status (input slot 12)
The AC-link protocol provides for a special 16-bit time slot (Slot 0) wherein each bit
conveys a valid tag for its corresponding time slot within the current audio frame.
A 1 in a given bit position of slot 0 indicates that the corresponding time slot within the
current audio frame has been assigned to a data stream, and contains valid data.
SYNC remains HIGH for a total duration of 16 BIT_CLKs at the beginning of each
audio frame. The portion of the audio frame where SYNC is HIGH is defined as the
Tag Phase. The remainder of the audio frame where SYNC is LOW is defined as the
“Data Phase”. Additionally, for power savings, all clock, sync, and data signals can be
halted. UCB1400 is implemented as a static design to allow its register contents to
remain intact when entering a power savings mode.
