LVDS vs Ethernet in ADAS Cameras

Juan Bernado
Prodigy 10 points


Hello everyone,

I am just starting an investigation project related with Adas cameras but I am in this moment trying to gather as much information as I can related with this systems.

First thing I can see is that there are cameras using LVDS systems for communication but also there are some moving to Ethernet.

Please can someone clarify what are the main differences between these 2 systems and for what use cases I would use each one?

I am sure more questions will come to my mind but I would like to start from the beginning actually.

Thank you very much for your support,

looking forward to seeing your responses,

Best regards,

Juan

    Hi Juan,

    Most ADAS cameras we see are remaining LVDS (FPD-Link). The reason being that the total system cost is low (i.e. no need for a MAC), low latency and no compression required.
    However, you are correct in that there are a few options for Ethernet. These though have the requirement of connecting up to a MAC and the video is compressed. Ethernet allows easy bidirectional communication though and is a network capable solution, which makes it a lot easier to control and monitor.
