ICS873039

LOW SKEW, ÷2/4,÷4/6,

LVPECL-TO-3.3V LVPECL / ECL CLOCK GENERATOR

The ICS873039 is a low skew, high performance LVPECL-to-3.3V LVPECL / ECL Clock Genera-

HiPerClockS tor/Divider and a member of the HiPerClockS
family of High Performance Clock Solutions from

ICS. The ICS873039 has one LVPECL differen-
tial clock input pair. The PCLK, nPCLK pair can accept

LVPECL, LVDS, CML, 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 ICS873039 ideal for clock distribution applications demanding well defined performance and repeatability.
