Description
The 87339I-11 is a low skew, high performance Differential-to-3.3V LVPECL Clock Generator/Divider. The 87339I-11 has one differential clock input pair. The CLK, nCLK pair can accept most standard differential input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Guaranteed output and part-to-part skew characteristics make the 87339I-11 ideal for clock distribution applications demanding well defined performance and repeatability.
