The GX34223 is a dual 46Gb/s linear Trans-Impedance Amplifier (TIA) for 400G coherent Receiver Optical Sub-Assemblies (ROSAs).

The GX34223 integrates two TIA signal paths for I and Q channels. The high-performance, low power, and compact design of the GX34223 enables small form factors like CFP2 and CFP4.
