Low Skew,1-to-2 Differential-TolvHSTL Fanout Buffer

NOTICE - The following device(s) are recommended alternatives:

The 85211I is a low skew, high performance 1-to-2 Differential-to-LVHSTL Fanout Buffer . The CLK, nCLK pair can accept most standard differential input levels.The 85211I is characterized to operate from a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 85211I ideal for those clock d i s t r i b u t i o n a p p l i c a t i o n s d e m a n d i n g w e l l d e f i n e d performance and repeatability. For optimal performance, terminate all outputs.

Features
