Input/Output Interfaces

5.7.1 HD Audio Controller

The HD Audio Controller is a PCI Express device that is integrated into the 82801 ICH component and supports the following functions:

Read/write access to audio codec registers

Support for greater than 48-KHz sampling

HD audio interface

5.7.2HD Audio Link Bus

The HD audio controller and the HD audio codec communicate over a five-signal HD Audio Link Bus (Figure 5-9). The HD Audio Interface includes two serial data lines; serial data out (SDO, from the controller) and serial data in (SDI, from the audio codec) 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 the 24-MHz BCLK signal driven by the audio controller. 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. When asserted (typically during a power cycle), the RESET- signal (not shown) will reset all audio registers to their default values.
