In this article, an encoder Application Specific Integrated Circuit (ASIC) for high-speed serial data transmission is presented. The ASIC implements a low-latency and low-overhead line code and is fabricated with a commercial 0.25-µm Silicon-on-Sapphire CMOS technology. The ASIC operates at 640 MHz with a latency of no greater than 6.25 ns and the overhead of 14.3%. The encoder will be integrated with a serialiser and will be used in the A Toroidal LHC ApparatuS Liquid Argon (LAr) calorimeter Phase-I trigger upgrade. [ABSTRACT FROM PUBLISHER]
