The HXR42100 Trans-impedance Limiting Amplifier array is a member of the family of Optical Receiver Transmitter Array (ORTA) products targeted at the single channel fiber optic links market. Together with a discrete PiN detector array, high-capacity, high-availability optical links can be designed for datacom applications. Ideal for 100G to 25G fan-out applications.

The 3.3V SiGe device integrates the trans-impedance pre-amplifier, the limiting post-amplifier, and a versatile CML output stage for a single, differential electrical channel.
