In the framework of the GigaBit Transceiver project (GBT), a prototype, the GBTSerDes ASIC, was developed, fabricated and tested. To sustain high radiation doses while operating at 4.8Gb/s, the ASIC was fabricated in a commercial 130 nm CMOS technology employing radiation tolerant techniques and circuits. The transceiver serializes-deserializes the data, Reed-Solomon encodes and decodes the data and scrambles and descrambles the data for transmission over optical fibre links. This paper describes the GBT-SerDes architecture, and presents the test results.
