SY89832U数据手册集成电路（IC）的时钟缓冲器驱动器规格书PDF

描述 Description

The SY89832U is a 2.5V, high-speed, 2GHz differential LVDS (Low Voltage Differential Swing) 1:4 fanout buffer optimized for ultra-low skew applications. Within device skew is guaranteed to be less than 20ps over supply voltage and temperature.The differential input buffer has a unique internal termination design that allows access to the termination network through a VT pin. This feature allows the device to easily interface to different logic standards. A VREF-AC reference output is included for AC-coupled applications.The SY89832U is a part of Micrel's high-speed clock synchronization family. For 3.3V applications, see SY89833L.For applications that require a different I/O combination, choose from a comprehensive product line of high-speed, low-skew fanout buffers, translators and clock generators.

简介

SY89832U属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY89832U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。
