7.1. Link Signals
The High Definition Audio (HDA) link is the digital serial interface that connects the HDA codecs to the
HDA Controller. The HDA link protocol is controller synchronous, based on a 24.0MHz BIT-CLK sent
by the HDA controller. The input and output streams, including command and PCM data, are isochronous
with a 48kHz frame rate. Figure 4 shows the basic concept of the HDA link protocol.
