AC/HDA_RST#
A30
High Definition Audio Reset: This signal is the master hardware reset to external codec(s). O 3.3VSB
AC’97 codecs are not supported.
AC/HDA_SYNC
A29
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.
O 3.3VSB
AC’97 codecs are not supported.
AC/HDA_BITCLK
A32
High Definition Audio Bit Clock Output: This signal is a 24.000MHz serial data clock
generated by the High Definition Audio controller.
O 3.3VSB
AC’97 codecs are not supported.
AC/HDA_SDOUT
A33
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.
O 3.3VSB
AC’97 codecs are not supported.
AC/HDA_SDIN[2:0] B28-B30 High Definition Audio Serial Data In [0]: These signals are serial TDM data inputs from
the three codecs. The serial input is single-pumped for a bit rate of 24 Mb/s for High
Definition Audio.
