PRODUCT OVERVIEW

The MX93002 PCM CODEC integrates key functions of the analog-front-end of DAM (with Digital Speakerphone) related products into an integrated circuit. The MX93002 PCM CODEC is especially powerful when applied to some DAM models which are intended to meet different countries specifications in the same system hardware. User can achieve this goal by simply setting control firmware. This benefit will help DAM system makers to save developing time and R&D resources.
