NB7V72M数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The NB7V72M is a high bandwidth, low voltage, fully differential 2 x 2 crosspoint switch with CML outputs. The NB7V72M design is optimized for low skew and minimal jitter as it produces two identical copies of Clock or Data operating up to 5 GHz or 6.5 Gb/s, respectively. As such, the NB7V72M is ideal for SONET, GigE, Fiber Channel, Backplane and other clock/data distribution applications. The differential IN/IN inputs incorporate internal 50-ohm termination resistors and will accept LVPECL, CML, or LVDS logic levels. The 16 mA differential CML outputs provide matching internal 50 ohm terminations and produce 400 mV output swings when externally terminated with a 50 ohm resistor to VCC. The NB7V72M is the 1.8 V/2.5 V CML version of the NB7L72M and is offered in a low profile 3 x 3 mm 16-pin QFN package.

简介

NB7V72M属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的NB7V72M信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
