Description

This Cypress series of network circuits are produced using

advanced 0.35-micron CMOS technology, achieving the

industry’s 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.
