Design of a Transceiver Transmitting Power, Clock, and Data over a Single Optical Fiber for Future Automotive Network System

This paper proposes a new link structure that transmits power, clock, and data through a single optical fiber for a future automotive network. A pulseposition modulation (PPM) technique is adopted to guarantee a DC-balanced signal for robust power transmission regardless of transmitted data pattern. Further, circuit implementations and theoretical analyses for the proposed PPM transceiver are described in this paper. A prototype transceiver fabricated in 65-nm CMOS technology, is used to verify the PPM signaling part of the proposed system. The prototype achieves a 10 bit-error rate and 0.188-UI high frequency jitter tolerance while consuming 14 mW at 800 Mb/s.
