SY89544U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 SY89544U is a fast, low-jitter, 4:1 differential MUX with an LVDS (350mV) compatible output with guaranteed data rate throughput of 3.2Gbps over temperature and voltage.The SY89544U differential inputs include a unique, 3-pin internal termination that allows access to the termination network through a VT pin. This feature allows the device to easily interface to different logic standards, both AC- and DC-coupled without external resistor-bias and termination networks. The result is a clean, stub-free, low-jitter interface solution.The SY89544U operates from a single 2.5V supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). For applications that require a 3.3V supply, consider the SY89545L. For applications that require two differential outputs, consider the SY89546U or SY89547L. The SY89544U is part of Micrel's Precision Edge® product family.

简介

SY89544U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SY89544U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。
