NB7V58M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 NB7V58M is a high performance differential 2-to-1 Clock or Data multiplexer. The differential inputs incorporate internal 50-ohm termination resistors that are accessed through the VT pin. This feature allows the NB7V58M to accept various logic level standards, such as LVPECL, CML or LVDS. The NB7V58M produces minimal Clock or Data jitter operating up to 7GHz or 10.7Gbps, respectively. As such, the NB7V58M is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The 16mA differential CML outputs provide matching internal 50-ohm terminations and 400mV output swings when externally terminated with a 50-ohm resistor to VCC. The NB7V58M is offered in a low profile 3mm x 3mm 16-pin QFN package and is a member of the GigaComm family of high performance Clock / Data products. For applications that require equalization, the pin-compatible NB7VQ58M is also available.

简介

NB7V58M属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的NB7V58M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。
