GENERAL DESCRIPTION

The 8737-11 is a low skew, high performance Differential-to-3.3V LVPECL Clock Generator/Divider. The 8737-11 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels.The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.

FEATURES
