The ICS8737-11 is a low skew, high performance
Differential-to-3.3V LVPECL Clock Generator/Divider. The
ICS8737-11 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 isinternally synchronized to
eliminate runt pulses on theoutputs during asynchronous
assertion/deassertion of the clock enable pin.
Guaranteed output and part-to-part skew characteristics
make the ICS8737-11 ideal for clock distribution applications
demanding well defined performance and repeatability.
