AN214, 6-Channel Audio Design

AN214 Application Note CS4201/CS4202 SIX CHANNEL AUDIO DESIGN 1.

INTRODUCTION This application note describes how to create a six channel AC '97 audio sub-system on a PC motherboard that can accommodate either the CS4201 or the CS4202 audio codec.

CS4201/CS4202 DUAL DESIGN Figure 1 illustrates a circuit that accommodates both CS4201 and CS4202 codecs, and Table 1 summarizes the population options.

The only changes necessary are to pins 32, 33, 34, and 48.

On the CS4201, pins 32-34 form the
