Overview
Description
The HXR8201 Trans-impedance Limiting Amplifier array is a member of IDT’s 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. The product is ideal for 100G to 25G fan-out applications. The 3.3V SiGe device integrates the transimpedance preamplifier, the limiting post-amplifier, and a versatile CML output stage for four optical channels.
