Description
Intel High Definition Audio Reset: This signal is the master hardware reset to
®
external codec(s).
Intel 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.
Intel High Definition Audio Bit Clock Output: This signal is a 24.000MHz
®
serial data clock generated by the Intel
Intel 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 Mbps for Intel ® High Definition Audio.
High Definition Audio Serial Data In 0: This signal is the serial TDM
®
data input from the codec(s). This serial input is single-pumped for a bit rate of
24 Mbps for Intel ® High Definition Audio.
