Overview
Description
The 87021I is a high performance ÷1/÷2 Differential-to-LVCMOS/LVTTL Clock Generator and a member of the family of High Performance Clock Solutions from IDT. The CLK, nCLK pair can accept most standard differential input levels. Guaranteed part-to-part skew characteristics make the 87021I ideal for those clock distribution applications demanding well defined performance and repeatability.
Features
