MAX3971A Datasheet, PDF (1/10 Pages) Maxim Integrated Products – +3.3V, 10.7Gbps Limiting Amplifier

19-2391; Rev 0; 4/02
+3.3V, 10.7Gbps Limiting Amplifier
General Description
The MAX3971A is a compact 10.7Gbps limiting amplifier.
It accepts signals over a wide range of input voltage levels
and provides constant-level output voltages with con-
trolled edge speeds. It functions as a data quantizer with
a 240mV_P-P differential CML output signal with a 100Ω dif-
ferential termination. The MAX3971A has a disable func-
tion that allows the outputs to be squelched if required by
the application.
The MAX3971A is designed to work with the MAX3970
transimpedance amplifier (TIA). The limiting amplifier
operates on a single +3.3V supply and functions over a
0°C to +85°C temperature range.
The MAX3971A is offered in die form and in a compact
4mm × 4mm 20-pin QFN package.
