HXR32400

HXR32400

The HXR32400 Trans-impedance Amplifier with Limiting Output stage, 4th generation device is a lower power member of the family of Optical Receiver Transmitter Array (ORTA) products targeted at the 28Gbps parallel optical links market. Together with a PIN detector array or discrete detectors, high-capacity, high-availability optical 100GBase-CLR4 links can be designed for telecom and datacom applications.

The SiGe device integrates the trans-impedance pre-amplifier, the limiting post-amplifier and a versatile CML output stage for four optical channels.
