link start-up sequence and the other mechanisms will be described. Using low-power mode comes last.
ACLC provides four mechanisms to operate AC’97-compliant CODEC(s):
This section first describes the CODEC connection, chip configuration, and overall usage-flow. Then AC-

supports up to two CODECs to be connected. This section shows some system configuration diagrams
for typical usages. Note that the diagrams shown here is intended to provide conceptual understanding
and some components may be necessary on the actual circuit board to ensure proper electrical signals.
The diagrams assume CODECs compliant with the CODEC ID strapping recommendation described in
the section D.5.2 of the AC’97 revision 2.1 specification.
The ACLC module has two SDIN (named as SDATA_IN in the AC’97 specification) signals and
