• Manufacturer Part Number: ICE1232
• Description: ac 97 2.1 VSR Audio Codec With 3D
• Manufacturer: IC Ensemble

Preliminary
Multiple Codec Example
One primary codec and three secondary codecs, with tag bits ID[1:0] defining which codec is primary and the
order of the secondary codecs. Note that the ID[1:0] pins are internally pulled up; therefore, it is necessary to
pull the ID[1:0] pins low to set the codec as secondary. Notice that the state of the ID[1:0] pins are reflected in
reverse polarity as shown on Table 19 on page 23.
