The HXR5004A Transimpedance Limiting Amplifier array is a member of the family of Optical Receiver Transmitter Array (ORTA) products targeted at the parallel optical links market. Together with a PIN detector array or discrete detectors, high capacity, high availability optical links can be designed for telecom and 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.
