    CM6610A

    Introduction

    Cmedia CM6610A is the world’s first USB2.0 high-speed audio processor that can support the latest USB Audio Class 2.0 and 2-channel true high-definition audio and Line-In/Mic-In. CM6610A reference design integrates CM9822 as the default codec to provide high-fidelity line output and headphone out up to 192KHz/24bit HD audio. It could also support 192KHz/24bit S/PDIF transmitter and receiver and also a USB2.0 MIDI I/O device for music creation applications. CM6610A has an embedded 8051 compatible microprocessor that can provide the best flexibility and functionality with the external upgradable 32KB NOR Flash ROM codes. With Cmedia versatile software technologies, CM6610A is a powerful audio core for high-value USB Audio Class 2.0 applications.
