A design of an optical transceiver SiP

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 line theory and finite elements method by combination of field solver and circuit simulator. Following the design flow, a SI simulation was made by using the model. Furthermore, a thermal analysis and design were made by ANSYS. At last, an optical transceiver is fabricated and tested.
