描述 Description

The SY58608U is a 2.5V, high-speed, fully differential 1:2 LVDS fanout buffer optimized to provide two identical output copies with less than 20ps of skew and less than 10psPP total jitter. The SY58608U can process clock signals as fast as 2GHz or data patterns up to 3.2Gbps.The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled) as small as 100mV (200mVPP) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an integrated voltage reference (VREF-AC) is provided to bias the VT pin. The outputs are 325mV LVDS, with rise/fall times guaranteed to be less than 100ps.The SY58608U operates from a 2.5V ±5% supply and is guaranteed over the full industrial temperature range (–40°C to +85°C). For applications that require CML or LVPECL outputs, consider Micrel’s SY58606U and SY58607U, 1:2 fanout buffers with 400mV and 800mV output swings respectively. The SY58608U is part of Micrel’s high-speed, Precision Edge® product line.

简介

SY58608U属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY58608U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。
