Description
The Cypress CY2 series of network circuits are produced
using advanced 0.35-micron CMOS technology, achieving the
industry’s fastest logic.
The Cypress CY2DP814 fanout buffer features a single LVDS-
or a single LVPECL-compatible input and four LVPECL output
pairs.
Designed for data communications clock management appli-
cations, the fanout from a single input reduces loading on the
input clock.
The CY2DP814 is ideal for both level translations from
single-ended to LVPECL and/or for the distribution of
LVDS-based clock signals. The Cypress CY2DP814 has
configurable input between logic families. The input can be
selectable for an LVPECL/LVTTL or LVDS signal, while the
output drivers support LVPECL capable of driving 50-ohm
lines.
