论文摘要
我们介绍了驱动程序的设计和测试结果，并限制了在10 Gbps（DLAS10）运行的ASIC和基于DLAS10的三个微型光学发射器/接收器/收发器模块（MTX+，MRX+和MTRX+）。 DLAS10可以驱动两个垂直腔表面发射激光器（VCSELS）的两个发射机光学子组件（TOSA），从两个接收器光学子组件（Rosas）接收信号，这些信号分别没有嵌入式限制放大器或驱动VCSEL TOSA，或者分别从ROSA接收信号。 DLAS10的每个通道都由输入连续时间线性均衡器（CTLE），四阶段限制放大器（LA）和输出驱动器组成。 LA将可变水平的信号放大到稳定的秋千。输出驱动程序驱动VCSEL或阻抗控制的轨迹。 DLAS10在65 nm CMOS技术中制造。模具为1 mm x 1 mm。 DLAS10包装在4 mm x 4 mm 24 pin Quad-Flat No-Leads（QFN）软件包中。 DLAS10已在MTX+，MRX+和MTRX+模块中进行了测试。测量的光学和电动眼图都通过了10 Gbps眼罩测试。输入电敏感性为40 MVP -P，而输入光学灵敏度为-12 dbm。 MRX+的总抖动为29 PS（P-P），随机抖动为1.6 PS（RMS），确定性抖动为9.9 PS。每个MTX+/MTRX+模块分别消耗82 MW/CH和174 MW/CH。
We present the design and test results of a Drivers and Limiting AmplifierS ASIC operating at 10 Gbps (DLAS10) and three Miniature Optical Transmitter/Receiver/Transceiver modules (MTx+, MRx+, and MTRx+) based on DLAS10. DLAS10 can drive two Transmitter Optical Sub-Assemblies (TOSAs) of Vertical Cavity Surface Emitting Lasers (VCSELs), receive the signals from two Receiver Optical Sub-Assemblies (ROSAs) that have no embedded limiting amplifiers, or drive a VCSEL TOSA and receive the signal from a ROSA, respectively. Each channel of DLAS10 consists of an input Continuous Time Linear Equalizer (CTLE), a four-stage limiting amplifier (LA), and an output driver. The LA amplifies the signals of variable levels to a stable swing. The output driver drives VCSELs or impedance-controlled traces. DLAS10 is fabricated in a 65 nm CMOS technology. The die is 1 mm x 1 mm. DLAS10 is packaged in a 4 mm x 4 mm 24-pin quad-flat no-leads (QFN) package. DLAS10 has been tested in MTx+, MRx+, and MTRx+ modules. Both measured optical and electrical eye diagrams pass the 10 Gbps eye mask test. The input electrical sensitivity is 40 mVp-p, while the input optical sensitivity is -12 dBm. The total jitter of MRx+ is 29 ps (P-P) with a random jitter of 1.6 ps (RMS) and a deterministic jitter of 9.9 ps. Each MTx+/MTRx+ module consumes 82 mW/ch and 174 mW/ch, respectively.
