SY55858U数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The SY55858U is a low-voltage, high-speed dual 2 x 2 crosspoint switch with a flexible input that accepts CML or PECL, and a 50Ω compatible differential CML (currentmode logic) output. The non-blocking design allows any input to connect to any output. Varying the state of the select inputs allows SY55858U to be used in backup, fault tolerant, protection and backplane distribution applications.The signal inputs (DA0-1 and DB0-1) have a unique internal termination design that allows access to the termination network through VT pins. This feature allows the device to easily interface to other logic standards such as AC-coupled or DC-coupled PECL/LVPECL signals. For applications that require a single-channel 2x2 crosspoint, consider the SY55854.

简介

SY55858U属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的SY55858U信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
