An electrical design and fabrication of a 12-channel optical transceiver with SiP packaging technology

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 of electrical channels, a signal integrity (SI) design flow based on Electromagnetic Analysis Method and Circuit Analysis Method is proposed. Following this design flow, the high speed link performs on a large bandwidth. With the electrical design, the optical transceiver is fabricated and tested.
