NB7V586M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 NB7V586M is a differential 1-to-6 CML 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 differential LVPECL, CML, or LVDS logic levels. The INx/INxb inputs and core logic are powered with a 1.8 V supply. The NB7V586M produces six identical differential CML output copies of Clock or Data. The outputs are configured as three banks of two differential pair. Each bank (or all three banks) have the flexibility of being powered by any combination of either a 1.8 V or 1.2 V supply. The 16 mA differential CML output structure provides matching internal 50-ohm source terminations and 400 mV output swings when externally terminated with a 50-ohm resistor to VCCOx. The 1:6 fanout design was optimized for low output skew and minimal jitter and is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications operating up to 6 GHz or 10 Gb/s typical. The VREFAC reference outputs can be used to rebias capacitor-coupled differential or single-ended input signals. The NB7V586M is offered in a low profile 5mm x 5mm 32-pin Pb-Free QFN package.

简介

NB7V586M属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的NB7V586M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。
