The HXR6104 transimpedance limiting amplifier array is a member of Renesas' 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 pre-amplifier, the limiting post-amplifier, and a versatile CML output stage for four optical input channels.
