General Description

The ONET4291PA is a versatile, high-speed, rate-selectable limiting amplifier for multiple fiber-optic applications with data rates up to 4.25 Gbps.

The device provides a two-wire interface, which allows digital bandwidth selection, digital output amplitude selection, and digital loss of signal threshold adjust.

This device provides a gain of about 43 dB, which ensures a fully differential output swing for input signals as low as 5 mVp-p.
