The HXR6212 Transimpedance Limiting Amplifier array is a member of IDT’s 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.
