HXR14150 Diagram


The HXR14150 is a single-channel, low-power Trans-impedance Linear Amplifier with built in clock and data recovery unit. It is a member of GigPeak’s family of Optical Receiver Transmitter Array (ORTA) products for the PAM4 modulation format 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 next-generation Ethernet and datacom applications.

The HXR14150 integrates the linear trans-impedance pre-amplifier, the linear post-amplifier, clock and data recovery unit, and a versatile CML output stage for four optical channels.
