Abstract

This paper presents an ASIC implementing the line encoding scheme to be used in the GBT system, a multi-gigabit optical link designed for use in a high energy physics environment. A general overview of issues specific to optical links placed in radiation environments is given, and the required properties of the line encoding discussed. A scheme that preserves the DC-balance of the line and allows forward error correction is proposed. It is implemented through the concatenation of scrambling, Reed-Solomon error-correction and addition of an 8-bit DC-balanced header. The proposed scheme has been implemented in a fully digital chip fabricated in a 0.13mum CMOS technology. Implementation details and test and simulation results are given
