ONET4291VARGPR TI Limiting Amplifier | 20-QFN (4x4) | 11.3 Gbps, 3.3V

Product Overview

The ONET4291VARGPR is a high-speed, single-channel limiting amplifier from Texas Instruments, designed for optical receiver applications. It operates at data rates up to 11.3 Gbps and provides a differential output with a typical small-signal bandwidth of 9 GHz. The device is housed in a compact 20-pin QFN package (4x4 mm) and operates from a single 3.3V supply. It features a programmable output swing and loss-of-signal (LOS) detection with adjustable threshold. The ONET4291VARGPR is ideal for use in 10G/40G Ethernet, Fibre Channel, and SONET/SDH systems.
