论文摘要
我们介绍了用于粒子物理实验的新型数据发射机ASIC ASIC的ASIC ASIC ASIC运行高达20.48 Gbps（PAM4）。这个名为GBS20的ASIC用65 nm的CMOS技术制造。两个连续序列共享5.12 GHz相锁定环（PLL）时钟。来自序列化器的输出被合并为PAM4信号，该信号直接驱动垂直腔表面发射激光器（VCSEL）。输入数据通道（在1.28 Gbps）都用内部的27-1伪随机二进制序列（PRB）炒作，该序列也用作框架对准器。 GBS20测试可在10.24和20.48 Gbps工作，并具有基于VCSEL的发射器 - 光套件（TOSA）。 GBS20的功耗低于238兆瓦，在低功率模式下降至164兆瓦。
We present the design and test results of a novel data transmitter ASIC operating up to 20.48 Gbps with 4-level Pulse-Amplitude-Modulation (PAM4) for particle physics experiments. This ASIC, named GBS20, is fabricated in a 65 nm CMOS technology. Two serializers share a 5.12 GHz Phase Locked Loop (PLL) clock. The outputs from the serializers are combined into a PAM4 signal that directly drives a Vertical-Cavity-Surface-Emitting-Laser (VCSEL). The input data channels, each at 1.28 Gbps, are scrambled with an internal 27-1 Pseudo-Random Binary Sequence (PRBS), which also serves as a frame aligner. GBS20 is tested to work at 10.24 and 20.48 Gbps with a VCSEL-based Transmitter-Optical-Subassembly (TOSA). The power consumption of GBS20 is below 238 mW and reduced to 164 mW in the low-power mode.
