    ATmega8 taillight circuitA more complex C program that implements different flashing patterns under the control of both the push buttons and potentiometer. Use your imagination to come up with some novel ideas here. Remember however that more marks are to be awarded for the quality of the code than for the novelness of the patterns.

  • 一種低成本高可靠的SFP+光收發模塊電路研究與實現

    本文首次設計并驗證了基于macom三合一芯片設計的光模塊電路,該電路旨在提供一種滿足SFF-8472中規定的數字診斷功能的低成本SFP+模塊。電路采用激光器驅動、限幅放大器、控制器以及時鐘恢復單元集成的單芯片,在保證高精度數字診斷功能基礎上,實現了低成本高可靠的特點。該電路在光接收接口組件與激光器驅動和限幅放大器單元的限幅放大器部分之間接入濾波器來提高模塊的靈敏度及信號質量。在控制器單元的數字電位器的引腳上采用外加電阻的方式避免出現上電不發光的故障問題。該研究結果為下一代SFP-DD光模塊設計與開發工作,奠定了一定的理論與實踐基礎。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.
