CY2DL814

1:4 Clock Fanout Buffer

Features

Description

• Low-voltage operation

• V_DD= 3.3V

• 1:4 Fanout

The Cypress CY2 series of network circuits is produced using

advanced 0.35-micron CMOS technology, achieving the

industry’s fastest logic.

The Cypress CY2DL814 fanout buffer features a single

LVDS-, LVPECL-, or LVTTL-compatible input and four LVDS

output pairs.

• Single-input configurable for

— LVDS, LVPECL, or LVTTL

— Four differential pairs of LVDS outputs

• Drives 50- or 100-ohm load (selectable)

• Low input capacitance

Designed for data-communication clock management applica-

tions, the fanout from a single input reduces loading on the

input clock.

• Low output skew

• Does not exceed Bellcore 802.3 standards

The CY2DL814 is ideal for both level translations from single

ended to LVDS and/or for the distribution of LVDS-based clock

signals. The Cypress CY2DL814 has configurable input and

output functions. The input can be selectable for

LVPECL/LVTTL or LVDS signals while the output driver’s

support standard and high drive LVDS. Drive either a 50-ohm

or 100-ohm line with a single part number/device.

• Operation at

350 MHz – 700 Mbps

• Low propagation delay Typical (tpd < 4 ns)

• Industrial versions available

• Packages available include TSSOP/SOIC
