论文摘要
本文介绍了几个组件原型,朝着专为Atlas液体氩气量热计相-I触发升级设计的低延迟,小型的光学链接。定制的双通道光学发射器模块的原型,微型光学发射器(MTX),具有单独的发射机光学子组件(TOSA)的原型,已以每个通道高达8 GBPS的数据速率证明了。已经开发了垂直腔室发射激光器(VCSEL)驱动器ASIC,并用于当前的MTX原型。已经设计和测试了一个以每通道8 Gbps运行的序列化器ASIC原型。已经设计和测试了低延迟的低延迟编码器ASIC原型。估计整个链接的潜伏期,包括发射器延迟和接收器潜伏期,而不是光纤的潜伏期,估计小于57.9 ns。 MTX的大小为45 mm x 15 mm x 6 mm。
This paper presents several component prototypes towards a low-latency, small-form-factor optical link designed for the ATLAS Liquid Argon Calorimeter Phase-I trigger upgrade. A prototype of the custom-made dual-channel optical transmitter module, the Miniature optical Transmitter (MTx), with separate transmitter optical sub-assemblies (TOSAs) has been demonstrated at data rates up to 8 Gbps per channel. A Vertical-Cavity Surface-Emitting Laser (VCSEL) driver ASIC has been developed and is used in the current MTx prototypes. A serializer ASIC prototype, operating at up to 8 Gbps per channel, has been designed and tested. A low-latency, low-overhead encoder ASIC prototype has been designed and tested. The latency of the whole link, including the transmitter latency and the receiver latency but not the latency of the fiber, is estimated to be less than 57.9 ns. The size of the MTx is 45 mm x 15 mm x 6 mm.
