The GX32223 is a dual-channel 32Gbps linear Trans-Impedance Amplifier (TIA) for 100G/200G Integrated Coherent Receivers (ICRs). The GX32223 integrates two TIA signal paths for I and Q channels. The high-performance, low power, and compact design of the GX32223 also enables a small-form factor integrated optical module such as CFP2 and CFP4.
