Summary:An integrated fiber-optic bit serializer and VCSEL driver has been constructed in radiation-hard complementary heterostructure GaAs FET (CHFET) technology. The serializer, which converts 20 parallel inputs into a high-speed serial output, consumes 60 mW at nominal supply voltage when operating at the Large Hadron Collider word rate of 40 MHz (0.8-GB/s serial rate). The integrated driver directly drives a VCSEL and provides 10-mA switched current and 5 mA of prebias. The complete digital optical link thus consumes 90 mW
