TI DS90UA101－Q1 多通道数字音频链路参考设计方案

TI公司的DS90UA101-Q1是一款提供多通道数字音频分配解决方案的串并、并串转换器芯片，嵌入式时钟通过双绞线或同轴电缆实现高速传输串并、并串转换器接口。串行总线方案通过链路支持高速前向数据传输和低速双向控制通道。本文首先介绍芯片的简介、特性、内部框图及应用领域，并给出相应设计方案的设计原理图及元器件列表。

The DS90UA101-Q1 Serializer, in conjunction with the DS90UA101-Q1 Deserializer, provides a solution for distribution of digital audio in multi-channel audio systems. It transmits a high-speed serialized interface with an embedded clock over a single shielded twisted pair or coaxial cable. The serial bus scheme supports high speed forward data transmission and low speed bidirectional control channel over the link. Consolidation of digital audio, general-purpose IO, and control signals over a single differential pair reduces the interconnect size and weight, while also reducing design challenges related to skew and system latency.
