Low-Jitter, Low-Noise LVPECL-to-LVDS Level Translator in an SC70 Package

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, 23psP-P added deterministic jitter and 0.6psRMS added random jitter ensure reliable communication 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.
