The GX3220 is a high performance 22.3 GB/s linear transimpedance amplifier IC with adjustable bandwidth control that enables its use in receiver modules for fiber optic transmission systems such as 40G RZ-DQPSK.

The GX3220 is designed for coherent optical receivers with high DC current cancellation, low Total Harmonic Distortion (THD) linear and a balanced TIA configuration. Input is differential and output is differential with AC coupling.
