Description
High Definition Audio Reset: This signal is the master hardware reset to external codec(s). O 3.3VSB
High Definition Audio Sync: This signal is a 48 kHz fixed rate sample sync to the codec(s).
It is also used to encode the stream number.
High Definition Audio Bit Clock Output: This signal is a 24.000MHz serial data clock
generated by the High Definition Audio controller.
High Definition Audio Serial Data Out: This signal is the serial TDM data output to the
codec(s). This serial output is double-pumped for a bit rate of 48 Mb/s for High Definition
Audio.
the three codecs. The serial input is single-pumped for a bit rate of 24 Mb/s for High
Definition Audio.
