概要

説明

The 87421I is a high performance ÷1/÷2 Differential-to-LVDS Clock Generator. The CLK, nCLK pair can accept most standard differential input levels. The 87421I is characterized to operate from a 3.3V power supply. Guaranteed part-to-part skew characteristics make the 87421I ideal for those clock distribution applications demanding well defined performance and repeatability.

特長
