Overview

Description

The HXR42400 Transimpedance and Limiting Amplifier array for LR4 parallel optical applications supports data rates up to 28Gbps and optical reach above +10km. Together with a four-channel photo diode array or discrete detectors, high-capacity, high-availability optical links can be designed for long reach telecom or datacom applications. The 3.3V SiGe device integrates the transimpedance preamplifier, the limiting post-amplifier, and a versatile CML output stage for four optical channels. Available in die form.
