The ICS8737I-11 is a low skew, high performance
Differential-to-3.3V LVPECL ClockGenerator/Divider. The
ICS8737I-11 has two selectable clock inputs. The CLK,
nCLK pair can acceptmost 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.
Guaranteed output and part-to-part skew characteristics make
the ICS8737I-11 ideal for clock distribution applications
demanding well defined performance and repeatability.
