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 50Ω

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.

Single LVDS/Anything-to-LVPECL Translator (VCC = +3.0V to +3.6V, differential input voltage |VID| = 0.1V to 1.2V, input frequency ≤ 1.34GHz, differential input transition time = 125ps (20% to 80%), input voltage (VIN, V IN) = 0 to VCC, input common-mode voltage VCM = 0.05V to (VCC - 0.05V), outputs terminated with 50Ω ±1% to VCC - 2.0V, TA = -40°C to +85°C. Typical values are at VCC = +3.3V, |VID| = 0.2V, input common-mode voltage VCM = 1.2V, TA = +25°C, unless otherwise noted.

Single LVDS/Anything-to-LVPECL Translator Output Termination Terminate the outputs with 50Ω to (VCC - 2V) or use equivalent Thevenin terminations. Terminate OUT and OUT with identical termination on each for low-output distortion. When a single-ended signal is taken from the differential output, terminate both OUT and OUT. Ensure that output currents do not exceed the current limits as specified in the Absolute Maximum Ratings.
