DS26519

16端口T1 / E1 / J1收发器

www.maxim-ic.com

概述

该DS26519是一个单芯片16端口成帧器和线路

对于T1 ，E1和J1接口单元（ LIU）的组合

应用程序。每个端口均可独立配置，

同时支持长途和短途线路。该

DS26519几乎是软件的兼容

DS26528及其衍生物。

特点

16完整的T1 ，E1或J1远程/

短程收发器（LIU加成帧器）

独立的T1 ，E1或J1选择的每一个

收发器

软件选择发送和接收 -

方终止对100Ω T1双绞线，

110Ω J1双绞线， 120Ω E1双绞线，

和75Ω同轴电缆

无缝保护开关

晶体抖动衰减器可以

选择发送或接收通道;抖动

衰减，符合ETS CTR 12/13 ， ITU -T

G.736 ， G.742 ， G.823和AT&T酒吧62411

外部主时钟可以是多个的

为2.048MHz或1.544MHz为T1 / J1或E1

操作;该时钟由内部改编

对于T1或E1使用的主机模式

接收信号电平指示从-2.5dB

到-36dB在T1模式和-2.5dB至-44dB的E1

模式近似2.5分贝增量
