1 Introduction

Advanced driver assistance systems (ADAS) have become increasingly more complex including applications such as driver monitoring, driver assistance features, and in some cases autonomous driving. These systems often use multiple types of sensors and cameras spread across various locations of the vehicle. As the number of sensors and cameras continue to increase, the total length and number of cables required to transfer the high-speed data and power signals will increase as well. This results in extensive cabling, which is costly and can complicate system implementation.

FPD-Link SerDes chipsets eliminate the need to have a separate cable to deliver power from the deserializer board to the serializer and sensor, which allows ADAS systems to support an increased number of sensors without an extensive amount of cabling. This is achieved by using Power over Coax (PoC) filters to separate DC power from the high speed FPD-Link signal, allowing power to be transferred over the same coax cable as the FPD-Link data.
