SY58020U中文资料Buffers数据手册Microchip规格书

描述 Description

The SY58020U is a 2.5V/3.3V precision, high-speed, fully differential 1:4 CML fanout buffer. Optimized to provide four identical output copies with less than 15ps of skew and less than 10psPP total jitter, the SY58020U can process clock signals as fast as 6GHz.The differential input includes Micrel's unique, 3-pin input termination architecture interfaces to differential LVPECL, LVDS, and CML signals (AC-coupled or DC-coupled) as small as 100mV without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an on-board output reference voltage (VREF-AC) is provided to bias the VT pin. The outputs are optimized to drive 400mV typical swing into 50Ω loads, with extremely fast rise/fall times guaranteed to be less than 60ps.The SY58020U 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). For applications that require LVPECL outputs, consider the SY58021U or SY58022U 1:4 fanout buffer with 800mV and 400mV output swing, respectively. The SY58020U is part of Micrel's high-speed, Precision Edge® product line.

简介

SY58020U属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY58020U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。
