SY56020XR中文资料Buffers数据手册Microchip规格书

描述 Description

The SY56020XR is a fully differential, low voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with input equalization. The SY56020XR can process clock signals as fast as 4.5GHz or data patterns up to 6.4Gbps.The differential input includes Micrel's unique 3-pin input termination architecture that interfaces to DC-coupled 2.5V/3.3V LVPECL, 1.2V/1.8V/2.5V CML or LVDS differential signals. For AC-coupled input applications, an internal voltage reference is provided for input bias. Input voltages as small as 200mV (400mVpp) are applied before the 9, 18, or 27-inch FR4 transmission line. The outputs are CML.The SY56020XR operates from a 2.5V ±5% core supply and a 1.2V, 1.8V or 2.5V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY56020XR is part of Micrel's high-speed, Precision Edge® product line.

简介

SY56020XR属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY56020XR时钟缓冲器，驱动器时钟缓冲器和驱动器集成电路产品族中的产品用于帮助信号在系统中传输，常用作频率/时间参考信号，以同步系统内的活动。尽管这些器件最常用到的功能就是缓冲（即，为使信号不受驱动负载的影响而从某个信号源复制信号），但是该产品族中的某些器件还能执行其他功能，例如选择性改变缓冲信号路径、按某个整数值分割信号频率，或进行所用电信号格式转换。
