NB3N853531E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 NB3N853531E is a low skew 3.3 V supply 2:1:4 clock distribution fanout buffer. An input MUX selects either a Fundamental Parallel Mode Crystal or a LVCMOS/LVTTL Clock by using the CLK_SEL pin (HIGH for Crystal, LOW for Clock) with LVCMOS / LVTTL levels. The single ended CLK input is translated to four LVPECL Outputs.Using the crystal input, the NB3N853531E can be a Clock Generator.A CLK_EN pin can enable or disable the outputs synchronously to eliminate runt pulses using LVCMOS/LVTTL levels (HIGH to enable outputs, LOW to disable output).

简介

NB3N853531E属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的NB3N853531E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。
