A 12-channel 3.125 Gb/s VCSEL driver IC has been designed in a SiGe BiCMOS process technology. The IC consists of 12 VCSEL drivers, a set of DACs providing per-channel adjustment of modulation and bias currents, peaking depth and width, and overcurrent threshold, and a three-wire serial interface which allows access to the DACs as well as internal registers for eye safety shutdown and other functions. The driver IC addresses many of the manufacturing issues in very short reach (VSR) parallel optical modules.
