NB7L14M数据手册开发板套件编程器的评估演示板及套件规格书PDF

描述 Description

The NB7L14M is a differential 1-to-4 clock/data distribution chip with internal source termination and CML output structure, optimized for low skew and minimal jitter. The device produces two identical output copies of clock or data operating up to 8 GHz or 12 Gb/s, respectively.Inputs incorporate internal 50 Ohm termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), CML, LVCMOS, LVTTL, or LVDS. Differential 16mA CML (Current Mode Logic) output provides matching 50 Ohm terminations, and 400 mV output swings when externally terminated, 50 Ohm to VCC.
