NB7L585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 NB7L585 is a differential 1:6 LVPECL Clock/Data distribution chip featuring a 2:1 Clock/Data input multiplexer with an input select pin. The INx/INxb inputs incorporate internal 50-ohm termination resistors and will accept LVPECL, CML, or LVDS logic levels. The NB7L585 produces six identical output copies of Clock or Data operating up to 5 GHz or 8 Gbps, respectively. As such, NB7L585 is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The NB7L585 is powered with either 2.5 V or 3.3 V supply. The NB7L585 is a member of the GigaComm™ family of high performance clock products.

简介

NB7L585属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的NB7L585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。
