SY100EP14U中文资料Buffers数据手册Microchip规格书

描述 Description

The SY100EP14U is a high-speed, 2GHz differential PECL/ECL 1:5 fanout buffer optimized for ultra-low skew applications. Within device skew is guaranteed to be less than 25ps over temperature and supply voltage. The wide supply voltage operation allows this fanout buffer to operate in 2.5V, 3.3V, and 5V systems. A VBB reference is included for single-supply or AC-coupled PECL/ECL input applications, thus eliminating resistor networks. When interfacing to a single-ended or AC-coupled PECL/ECL input signal, connect the VBB pin to the unused /CLK pin, and bypass the pin to VCC through a 0.01µF capacitor.The SY100EP14U features a 2:1 input MUX, making it an ideal solution for redundant clock switchover applications. If only one input pair is used, the other pair may be left floating. In addition, this device includes a synchronous enable pin that forces the outputs into a fixed logic state. Enable or disable state is initiated only after the outputs are in a LOW state, thus eliminating the possibility of a \"runt\" clock pulse.The SY100EP14U I/O are fully differential and 100K ECL compatible. Differential 10K ECL logic can interface directly into the SY100EP14U inputs.The SY100EP14U is part of Micrel's high-speed clock synchronization family. For applications that require a different I/O combination, choose from a comprehensive product line of high-speed, low-skew fanout buffers, translators, and clock generators.

简介

SY100EP14U属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的SY100EP14U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。
