SY75572L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 SY75572L is a high-speed, fully differential 1:2 clock fanout buffer with a 2:1 input MUX optimized to provide two identical output copies with 137fs phase jitter and a maximum of 50ps output-to-output skew. Designed to be used with PCI Express applications, the SY75572L accepts and outputs HCSL or LVDS logic levels.The SY75572L operates from a 3.3V ±5% power supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). It is available in a 16-pin QFN lead-free package.The SY75572L is part of Micrel’s high-speed, ultra-low jitter, PrecisionEdge™ product line. The SY75572L supports PCIe Gen1-Gen3 requirements with sufficient performance margin for pending PCIe Gen4 applications.

简介

SY75572L属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY75572L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。
