5.8.2 AC97 AUDIO CONTROLLER

The AC97 Audio Controller is a PCI device (device 31/function 5) that is integrated into the

82801 ICH component and supports the following functions:

♦

♦

Read/write access to audio codec registers

16-bit stereo PCM output @ up to 48 KHz sampling

16-bit stereo PCM input @ up to 48 KHz sampling

Acoustic echo correction for microphone

5.8.3 AC97 LINK BUS

The audio controller and the audio codec communicate over a five-signal AC97 Link Bus (Figure

5-12). The AC97 Link Bus includes two serial data lines (SD OUT/SD IN) that transfer control

and PCM audio data serially to and from the audio codec using a time-division multiplexed

(TDM) protocol. The data lines are qualified by a 12.288 MHz BIT_CLK signal driven by the

audio codec. Data is transferred in frames synchronized by the 48-KHz SYNC signal, which is

derived from the clock signal and driven by the audio controller. The SYNC signal is high during

the frame’s tag phase then falls during T17 and remains low during the data phase. A frame

consists of one 16-bit tag slot followed by twelve 20-bit data slots. When asserted (typically

during a power cycle), the RESET- signal (not shown) will reset all audio registers to their default

values.
