ICS83940

LOW SKEW, 1-TO-18

LVCMOS FANOUT BUFFER

PRELIMINARY

GENERAL DESCRIPTION

The ICS83940 is a low skew, 1-to-18 Fanout

Buffer and a member of the HiPerClockS™

family of High Performance Clock Solutions from

ICS. The low impedance LVCMOS out-

puts are designed to drive 50

Ω series or parallel

terminated transmission lines. The effective fanout can be in-

creased from 18 to 36 by utilizing the ability of the outputs to

drive two series terminated lines. The differential clock

input is designed to accept any differential input levels

including LVPECL.

The ICS83940 is characterized at full 3.3V, full 2.5V and mixed

3.3V input and 2.5V output operating supply modes. Guaran-

teed output and part-to-part skew characteristics make the

ICS83940 ideal for those clock distribution applications de-

manding well defined performance and repeatability.
