A 250Mb/s CMOS optoelectronic transmitter and receiver IC for next-generation in-vehicle networks

In this paper, optoelectronic transmitter and receiver IC for next-generation in-vehicle networks is designed and implemented using a standard CMOS technology. Despite of using a plastic optical fiber (POF) as a transmission medium, the next generation in-vehicle networks require wider bandwidth than the past one. To meet the bandwidth requirement, low-voltage differential signaling (LVDS) is preferred as an electrical interface. The transmitter and receiver IC can operate up to 250Mb/s of bit rates through a full optical link. -24dBm and -22.6dBm of optical sensitivities are respectively achieved for 10 -9 and 10 -12 of bit error rate (BER) at 250Mb/s.
