Description
This Cypress series of network circuits are produced using
advanced 0.35-micron CMOS technology, achieving the
industry鈥檚 fastest logic.
The Cypress CY2DP818 fanout buffer features a single LVDS
or a single-ended LVTTL-compatible input and eight LVPECL
output pairs.
Designed for data-communications clock-management appli-
cations, the large fanout from a single input reduces loading
on the input clock.
The CY2DP818 is ideal for both level translations from
single-ended to LVPECL and/or for the distribution of
LVPECL-based clock signals.
The Cypress CY2DP818 has configurable input functions. The
input is user configurable via the Inconfig pin for single ended
or differential input.
