MAXIM MAX9376 User Manual

General Description

The MAX9376 is a fully differential, high-speed, LVDS/anything-to-LVPECL/LVDS dual translator designed for signal rates up to 2GHz. One channel is LVDS/anything-to-LVPECL translator and the other channel is LVDS/anything-to-LVDS translator. The MAX9376’s extremely low propagation delay and high speed make it ideal for various high-speed network routing and backplane applications.

The MAX9376 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. LVPECL outputs have sufficient current to drive 50Ω transmission lines. LVDS outputs conform to the ANSI EIA/TIA-644 LVDS standard.

The MAX9376 is available in a 10-pin µMAX

package and operates from a single +3.3V supply over the -40°C to +85°C temperature range.

otherwise noted.) (Notes 2, 3, 4)

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.
