Quad Differential LVECL-to-LVPECL Translators

General Description

Features

The MAX9420–MAX9423 are extremely fast, low-skew

quad LVECL-to-LVPECL translators designed for high-

speed signal and clock driver applications. The

devices feature ultra-low propagation delay of 336ps

and channel-to-channel skew of 17ps.

ꢀ >500mV Differential Output at 3.0GHz Clock

ꢀ 336ps (typ) Propagation Delay in Asynchronous

Mode

ꢀ 17ps (typ) Channel-to-Channel Skew

The four channels can be operated synchronously with

an external clock, or in asynchronous mode, deter-

mined by the state of the SEL input. An enable input

provides the ability to force all the outputs to a differen-

tial low state.

ꢀ Integrated 50Ω Outputs (MAX9421/MAX9423)

ꢀ Integrated 100Ω Inputs (MAX9422/MAX9423)

ꢀ Synchronous/Asynchronous Operation

These devices operate with a negative supply voltage

of -2.0V to -3.6V, compatible with LVECL input signals.

The positive supply range is 2.375V to 3.6V for differen-

tial LVPECL output signals.

OUTPUT

PACKAGE INPUT

A variety of input and output terminations are offered for

maximum design flexibility. The MAX9420 has open

inputs and open-emitter outputs. The MAX9421 has

open inputs and 50Ω series outputs. The MAX9422 has

100Ω differential input impedance and open-emitter

outputs. The MAX9423 has 100Ω differential input

impedance and 50Ω series outputs.

The MAX9420–MAX9423 are specified for operation

from -40°C to +85°C, and are offered in space-saving

32-pin 5mm ✕ 5mm TQFP and 32-lead 5mm ✕ 5mm

QFN packages.
