General Description

The MAX9181 is an LVPECL-to-LVDS level translator

that accepts a single LVPECL input and translates it to

a single LVDS output. It is ideal for interfacing between

LVPECL and LVDS interfaces in systems that require

minimum jitter, noise, power, and space.

nication in high-speed links that are highly sensitive to

timing errors, especially those incorporating clock-and-

data recovery, PLLs, serializers, or deserializers. The

MAX9181’s switching performance guarantees a

400Mbps data rate, but minimizes radiated noise by

guaranteeing 0.5ns minimum output transition time.

The MAX9181 operates from a single 3.3V supply and

consumes only 10mA supply current over a -40°C to

+85°C temperature range. It is available in a tiny 6-pin

SC70 package (half the size of a SOT23). Refer to the

MAX9180 data sheet for a low-jitter, low-noise LVDS

repeater in an SC70 package.
