TSER953: FPD3-Link Cable Requirements

Armin Reule

Part Number: TSER953

Hello TI Team,

I plan to use TSER953 in a camera application on a movable device. The coax cable will be at least 5m long.

There are a few documents explaining that the attenuation should be as low as possible, and information about the return loss / insertion loss of the pcb. I failed to find any information about the maximum possible insertion loss of the system.

As I want to use a very flexible coax cable the attenuation is already quiet high(and if I want to be cost efficient, it will be even higher). Therefore information about the maximum attenuation of the system would be really nice to have.

If this isn't possible, I would appreciate Information about the cables of test system you used to at least have an indication what is working.

Thanks,

Armin

    Hey Armin,

    Please take a look at Table 8-2 in the TSER953 datasheet. This table summarizes the channel specifications that should be used.

    If you need further information, please contact your FAE/TSR, and they can help. :) 

    Thanks!

    Thanks for your reply Lysny,

    the table you're talking about is a table about the insertion loss of the pcb. "The suggested characteristics for single-ended PCB traces (microstrips or striplines) for serializer or deserializer boards are listed in Table 8-2"

    Also the cables I'm looking at have an attenuation of 2-3 dB/m excluding connectors. If I want to get to -0.6 dB for the whole network, the cables and connectors will cost multiple times the whole camera without taking into account the needed flexibility of the cable.

    Hey Armin,

    For further channel specification information, please reach out to your FAE/TSR like I mentioned. They can help guide you through the process of accessing additional channel spec information that will cover the tolerance for a cable assembly.

    Thanks!
