3.3V, 10.3Gbps Limiting Amplifier

The MAX3971 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 100Ω differential termination.

The MAX3971 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 the 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 MAX3971 is offered in die form and in a compact 4mm x 4mm, 20-pin QFN plastic package.
