We present an R&D program to develop an ASIC that contains a 12-channel VCSEL (Vertical Cavity Surface Emitting Laser) array driver operating at 10 Gb/s per channel, yielding an aggregated bandwidth of 120 Gb/s. The design of the 10 Gb/s array driver ASIC is based on a prototype ASIC for driving a VCSEL array at 5 Gb/s. We will briefly describe the design of the 5 Gb/s ASIC that was fabricated...
We have designed three ASICs for possible applications in the optical links of a new layer of pixel detector to be install inside the ATLAS detector for the first phase of the LHC luminosity upgrade. The ASICs include a high-speed driver for the VCSEL, a receiver/decoder to decode the signal received at the PIN diode to extract the data and clock, and a clock multiplier to produce a higher frequency...
