I. Device Description

A. General

The MAX3971A is a compact, low-power, 10.3Gbps limiting amplifier. It accepts signals over a wide range of input

voltage levels and provides constant-level output voltages with controlled edge speeds. It functions as a data quantizer.

The output of the amplifier is a 250mVp-p differential CML signal with a 100

differential termination.

The MAX3971A is designed to work with the MAX3970, a 10.3Gbps transimpedance amplifier (TIA). The limiting

amplifier operates on a single +3.3V supply and consumes only 155mW. The part functions over a 0°C to +85°C

temperature range. It also has a disable function that allows the outputs to be squelched if required by the application.

The MAX3971A is offered in either die form or in a compact 4mm x 4mm, 20-pin QFN plastic package.
