78P235x E4/STM1e LIU的设计准则

摘要： Teridian的78P2351和78P2352是第二代的线路接口单元（LIU ）芯片的OC -3 ， STS -3 ， STM-1或EF电信接口。此文件提供的建议，可以帮助减轻不必要的噪音，由于各地的刘次优板布局。它还提供了为满足严格的回波损耗和代码矩阵插入（CMI）的发射脉冲形状的要求，这两者都在很大程度上取决于PCB的设计和布局的一般准则。

Introduction
The Teridian 78Q8392L 10BASE-2 Transceiver IC can be used as a replacement for other industry standard
8392s. However, there are some differences between the Teridian 8392L and competitor’s versions of the 8392.
This application note describes the differences and required circuit changes, if necessary, to use the 78Q8392L
as a replacement for
