Description

We report the development of a VCSEL driver based on a commercial 0.25-micron silicon-on-sapphire CMOS technology. The driver is designed with a speed of 8 Gb/s with I2C configuration. The QFN packaged prototype measures up to 10 Gb/s in a miniature dual channel optical transmitter module called MTx. The ASIC and the custom MTx are prototypes for an optical link that is under development to read out the front-end board in the trigger upgrade of the Liquid Argon Calorimeter (LAr) in ATLAS. We will present design details, prototype measurement results including those from irradiation tests. We will also discuss the experience on the QFN package for high-speed signals.
