Upon release of reset, the CS4398 will detect the status of the MUTEC pins (high or low) and will then select that state as the polarity to drive when the mutes become active. The external mute circuitry needs to be self biased into an active state in order to be muted during reset.

The CS4398 accepts PCM data at sample rates from 32 kHz to 200 kHz, DSD audio data, has selectable dig- ital filters, consumes little power, and delivers excellent sound quality. It also offers an optional path for direct DSD conversion by di- rectly using the multi-element switched capacitor array. Copyright © (All Rights Reserved) CS4398 ultibit lte r.
