串行解串器(SerDes)的四种不同架构和应用

5星 · 资源好评率100%

When most system designers look at serializer/deserializer (SerDes) devices, they often compare speed and power without considering how the SerDes works and what it actually does with their data. Internal SerDes architecture may seem irrelevant, but this overlooked item can dictate many important system parameters like system topology, protocol overhead, data formatting and flow, latency, clocking and timing requirements, and the need for additional buffering as well as logic. These issues can have a big impact on system cost, performance, and efficiency.

SerDes是一种串行器/解串器，用于将并行数据转换为串行数据，或将串行数据转换为并行数据。其中，8b10b编码是一种常用的串行数据编码方式，它将8个数据位和2个控制位组成10位数据块，以此来保证传输的稳定性和可靠性。8b10b编码在高速串行通信中广泛使用，例如PCI Express、SATA、USB3.0等标准中都采用了该编码方式。
