CIRRUS LOGIC PRODUCT DATA SHEET

The dual codec architecture of AC ‘97, version 2.1, is supported wherein the second codec uses the same

pins from the primary, with the exception of a separate serial data-in line (ASDIN2) illustrated in

Figure 10. The Primary Codec is the timing master for the digital audio link and the CS4281. The ASD-

OUT output supports data transmission on nine of the output sample slots (output slots 3 - 11). The ASDIN

and ASDIN2 inputs support receiving of audio sample data on nine of the input sample slots (input slots

3 - 11).
