CDCLVC1310集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

CDCLVC1310属于集成电路（IC）的时钟缓冲器驱动器。由德州仪器制造生产的CDCLVC1310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。

DESCRIPTION

The CDCLVC1310 is a highly versatile, low-jitter, low-

power clock fanout buffer which can distribute to ten

low-jitter LVCMOS clock outputs from one of three

inputs, whose primary and secondary inputs can

feature differential or single-ended signals and crystal

input. Such a buffer is good for use in a variety of

mobile and wired infrastructure, data communication, computing, low-power medical imaging, and portable

test and measurement applications. When the input is

an illegal level, the output is at a defined state. One

can set the core to 2.5 V or 3.3 V, and output to 1.5

V, 1.8 V, 2.5 V or 3.3 V. Pin programming easily

configures the CDCLVC1310. The overall additive jitter performance is 25 fsRMS (typical). The

CDCLVC1310 comes in a small 32-pin 5-mm × 5-mm

QFN package.
