音频光纤同轴发射器方案CS8406+MS1808,附带电路图参考设计

W18938047300

音频光纤同轴发射器方案可以由CS8406+MS1808来做成。具体以下为音频光纤同轴发射芯片CS8406和音频ADC芯片MS1808详细介绍。深圳锦宏世纪/李先生18938047300
MS1808 是带有采样速率 8kHz ~ 96kHz 的立体声 A/D 转换器，适合于面向消费者的专业音频系统。
MS1808 通过使用增强型双位  技术来实现其高精度的特点。MS1808 是单端的模拟输入所以不需要外部器件。音频接口有两种类型(最高有效位对齐， I 2S )适合用于像 DTV,DVR 和 AV 接收器的系统。

# s; Y/ e' t* c) S/ ~" U! AThe CS8406 is a monolithic CMOS device which encodes and transmits audio data according to the AES3,IEC60958, S/PDIF, o r EIAJ CP1201 standards. The
+ o1 Z5 j+ a6 w; [2 W3 k; \CS8406 accepts audio and digital data, which is thenmultiplexed, encoded, and driven onto a cable.
The audio data is input through a configurable, 3-wireinput port. The channel status and user bit data are input through an SPI™ or I2C® microcontroller port, and
may be assembled in block-sized buffers. For systemswith no microcontroller, a Stand-Alone Mode allows direct access to channel status and user bit data pins.
' z- ]* ~1 l! _2 y7 D3 b  JThe CS8406 is available in a 28-pin TSSOP and SOICpackage for both Co mmercial (-10o to +70oC) andAutomotive grade (-40o to +85oC). The CDB8416Demonstration board is also available for deviceevaluation and implementation suggestions. Please
