描述 Description

The SY58033U is a 2.5V/3.3V precision, high-speed, fully differential 400mV LVPECL 1:8 fanout buffer. The SY58033U is optimized to provide eight identical output copies with less than 20ps of skew and only 76fsRMS phase jitter. It can process clock signals as fast as 5.5GHz.The differential input includes Micrel's unique, 3-pin input termination architecture that allows the SY58033U to directly interface to LVPECL, CML, and LVDS differential signal (AC‑ or DC-coupled) without any level-shifting or termination resistor networks in the signal path. The result is a clean, stub-free, low-jitter solution. The LVPECL (100k temperature compensated) outputs feature a 400mV typical swing into 50ý loads, and provide an extremely fast rise/fall time guaranteed to be less than 80ps.The SY58033U operates from a 2.5V ±5% supply or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). Other high-speed 1:8 fanout buffers include the CML SY58031U and the 800mV LVPECL SY58032U. The SY58033U is part of Micrel's highspeed, Precision Edge® product line.

简介

SY58033U属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY58033U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。
