SY58012U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 SY58012U is a 2.5V/3.3V precision, high-speed, fully differential 1:2 LVPECL fanout buffer. Optimized to provide two identical output copies with less than 15ps of skew and less than 10ps(pk-pk) total jitter, the SY58012U can process clock signals as fast as 5GHz or 5Gbps data.The differential input includes Micrel's unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential 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 100k LVPECL compatible, with extremely fast rise/fall times guaranteed to be less than 110ps.The SY58012U 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 faster rise/fall times, or greater bandwidth, consider the SY58013U 1:2 fanout buffer with 400mV output swing, or the SY58011 1:2 CML (400mV) fanout buffer. The SY58012U is part of Micrel's high-speed, Precision Edge® product line.

简介

SY58012U属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY58012U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。
