本文介绍了ATLAS液氩量热仪触发器升级的发射机专用集成电路LOCx 2的设计和测试结果。LOCx 2由两个通道组成，每个通道编码ADC数据的开销为14.3%，并以5.12 Gbps的速率传输串行数据，延迟小于27.2 ns。LOCx 2采用商用0.25 μm Silicon-on-Sapphire CMOS工艺制造，采用100引脚QFN封装。LOCx 2的功耗约为843 mW。
In this paper, we present the design and test results of LOCx2, a transmitter ASIC for the ATLAS Liquid Argon Calorimeter trigger upgrade. LOCx2 consists of two channels and each channel encodes ADC data with an overhead of 14.3% and transmits serial data at 5.12 Gbps with a latency of less than 27.2 ns. LOCx2 is fabricated with a commercial 0.25-μm Silicon-on-Sapphire CMOS technology and is packaged in a 100-pin QFN package. The power consumption of LOCx2 is about 843 mW.
