  • 一种低成本高可靠的SFP+光收发模块电路研究与实现

    本文首次设计并验证了基于macom三合一芯片设计的光模块电路,该电路旨在提供一种满足SFF-8472中规定的数字诊断功能的低成本SFP+模块。电路采用激光器驱动、限幅放大器、控制器以及时钟恢复单元集成的单芯片,在保证高精度数字诊断功能基础上,实现了低成本高可靠的特点。该电路在光接收接口组件与激光器驱动和限幅放大器单元的限幅放大器部分之间接入滤波器来提高模块的灵敏度及信号质量。在控制器单元的数字电位器的引脚上采用外加电阻的方式避免出现上电不发光的故障问题。该研究结果为下一代SFP-DD光模块设计与开发工作,奠定了一定的理论与实践基础。This paper designs and validates the optical module circuit based on the MACOM Trinity chip for the first time.This circuit aims to provide a low-cost SFP module which meets the digital diagnosis function specified in SFF-8472.The circuit uses a single chip integrated with laser driver,limiting amplifier,controller and clock recovery unit.On the basis of ensuring high precision digital diagnosis function,it achieves the characteristics of low cost and high reliability.The circuit connects a filter between the optical receiving interface module and the limiting amplifier part of the laser driver and limiting amplifier unit to improve the sensitivity and signal quality of the module.The pin of the digital potentiometer in the controller unit is equipped with an external resistance to avoid the problem of power failure.The research results lay a theoretical and practical foundation for optical module design in high-speed data center.

  • SiI9135芯片手册

    Introduction The Sil9135/Sil9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs is a second-generation dual-input High Definition Multimedia Interface(HDMI)receiver. It is software-compatible with the Sil9133receiver, but adds audio support for DTS-HD and Dolby TrueHD. Digital televisions that can display 10-or 12-bit color depth can now provide the highest quality protected digital audio and video over a single cable. The Sil9135and Sil9135A devices, which are functionally identical, can receive Deep Color video up to 12-bit,1080p @60Hz. Backward compatibility with the DVI 1.0specification allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set-top boxes and PCs. Silicon Image HDMI receivers use the latest generation Transition Minimized Differential Signaling(TMDS) core technology that runs at 25-225 MHz.The chip comes pre-programmed with High-bandwidth?
