÷1/÷2 Differential-to-LVPECL Clock Generator

The 87321I is a high performance ÷1, ÷2 Differential-to-LVPECL Clock Generator and a member of the amily of High Performance Clock Solutions from IDT. The CLK, nCLK pair can accept most standard differential input levels. The 87321I is characterized to operate from a 3.3V or 2.5V power supply. Guaranteed part-to-part skew characteristics make the 87321I ideal for those clock distribution applications demanding well defi ned performance and repeatability.
