The GigaBit Laser Driver (GBLD) is a radiation tolerant ASIC designed to drive both edge emitting lasers and VCSELs at data rates up to 5 Gb/s. It is part of the GigaBit Transceiver (GBT) project, which aims at the design of an optical transceiver capable to operate in the radiation environment of a typical HEP experiment. The GBLD can provide a modulation current of up to 24 mA and a laser bias current of up to 43 mA. Pre- and deemphasis functions are implemented to compensate for high external capacitive loads and asymmetric laser response. The chip, designed in CMOS 130 nm technology, is powered by a single 2.5 V power supply can be programmed via an I 2 C interface.
