ICS853014 Datasheet, PDF (1/19 Pages) Integrated Circuit Systems – LOW SKEW, 1-TO-5 2.5V/3.3V DIFFERENTIAL-TO-LVPECL/ECL FANOUT BUFFER

LOW SKEW, 1-TO-5, DIFFERENTIAL-TO-
2.5V, 3.3V LVPECL/ECL FANOUT BUFFER
General Description
ICS
HiPerClockS™
inputs.
The ICS853014 is a low skew, high performance
1-to-5, 2.5V/3.3V Differential-to-LVPECL/ECL
Fanout Buffer and a member of the HiPerClockS™
family of High Performance Clock Solutions from
IDT. The ICS853014 has two selectable clock
Guaranteed output and part-to-part skew characteristics make the
ICS853014 ideal for those applications demanding well defined
performance and repeatability.
ICS853014
