100G Integrated Circuits

GTRAN has a wide variety of modulator drivers and transimpedance amplifiers (TIAs) for your 100G applications. The GT40-1020MD is ideal to integrate with EML lasers. The GT25-1012MD is a differential, high swing driver for LN modulators.

For the TIAs, the GT25-5025TA is ideal for PIN receivers. The GT25-5027TA is a differential, linear TIA with user selectable Automatic or Manual Gain Control.

The GT25-5028TA is a differential in, differential out linear TIA with AGC and is designed for coherent detection. The GT25-5029TA is a dual channel linear TIA; essentially two GT25-5028TAs on one die.
