This paper presents development and characterization of a 3.2 Gb/s serial link transmitter for CMOS image sensors. The transmitter incorporates Reed-Solomon code to achieve low error rate in the harsh environment of subatomic physics experiments. Pre-emphasis is implemented in the transmitter, allowing data transmission over low-mass cables. It is fabricated in a 0.18 μm CMOS image process as a standalone chip to characterize its performance, with the core area of 1.8 mm2. A frame data rate of 3⋅10−12 with a confidence level of 94.5% was measured through an FPGA based receiver. The measured nominal power consumption is 135 mW. The transmitter functions normally after irradiated with 4.5 Mrad TID.
