VIS-Datasheet-T56-250C_v1_1

The T56-250C is a high speed transimpedance amplifier (TIA) IC designed for use by 56G receiver modules in fiber optic transmission systems. The T56-250 operates from a single +3.3 V supply typically dissipating 250 mW of DC power and is designed for the use with PIN photodetectors in a wire-bond assembly The IC has a single-ended input (IN) and a differential output (OutP, OutN). It includes the cathode connection for the photodiode (Cath) as well as a bias path through the internal pin (PD). The TIA features input/output DCoffset cancellation and is equipped with various analog control pins (NoXing, Vxing, Vmod and BW) which allow for zero-crossing adjustment, gain and peaking control.
