MAX9375EUA+

General Description
The MAX9375 is a fully differential, high-speed, any-
thing-to-LVPECL translator designed for signal rates up
to 2GHz. The MAX9375’s extremely low propagation
delay and high speed make it ideal for various high-
speed network routing and backplane applications.
The MAX9375 accepts any differential input signal within
the supply rails and with minimum amplitude of 100mV.
Inputs are fully compatible with the LVDS, LVPECL,
HSTL, and CML differential signaling standards. Outputs
are LVPECL and have sufficient current to drive 50
transmission lines.
The MAX9375 is available in an 8-pin µMAX package
and operates from a single +3.3V supply over the -40°C
to +85°C temperature range.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
