This paper presents an electrical design of a 6.25Gbps×12-channel parallel optical transceiver with SiP packaging technology. Considering such high speed, a low impedance and low noise power distribution network (PDN) is designed to suppress simultaneous switching noise (SSN) and a novel embedded capacitor filter is used to replace the conventional power supply filter. To minimize the impedance discontinuity...
This paper presents a design of an optical transceiver SiP with an embedded capacitor which replace conventional filter network and suppress switching noise with a large bandwidth in multi-GHz PCBs. A SI design method was proposed based on electromagnetic analysis method and circuit analysis method. To study SI, a SPICE equivalent circuit model of the high speed I/O link was built based on transmission...
The fabrication process of a 12-channel parallel optical transceiver module developed in our group is presented in this paper. The module is composed of a VCSEL array, a PIN PD array, a VCSEL driver chip, a TIA/LA chip and supporting PCB and connector. A SiOB and its vertical assembly are emphasized as the highlights of the structure of this module, which is promising to effectively reduce the package...
