Low-Jitter, Low-Noise LVPECL-to-LVDS Level
Translator in an SC70 Package
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.
Ultra-low, 23ps_P-P added deterministic jitter and
0.6ps_RMS added random jitter ensure reliable commu-
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.
