Low-Jitter, Low-Noise LVPECL-to-LVDS Level
Translator in an SC70 Package
General Description
Features
The MAX9156 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.

RMS
o 0.5ns (min) Transition Time Minimizes Radiated
nication in high-speed links that are highly sensitive to
timing errors, especially those incorporating clock-and-
data recovery, PLLs, serializers, or deserializers. The
MAX9156’s switching performance guarantees a
200Mbps data rate, but minimizes radiated noise by
guaranteeing 0.5ns minimum output transition time.

Standard
The MAX9156 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
MAX9155 data sheet for a low-jitter, low-noise LVDS
repeater in an SC70 package.
