Part Number: SN65LVDS116

I am using SN65LVDS116 repeater to receive LVDS signal and sending to another SN65LVDS116.In this way  1 signal is distributed to 90 signals.Final signal is taken to another module placed 1.5 m away by twisted PTFE wires.Please confirm the functionality.

Regards,

Amrita Gupta

    Hi,

    This really depends on several parameters as you know, including the signalling rate and the characteristics of the specific media you are using, among others.
    Please check this app note slla053: Performance of LVDS with Different Cables (Rev. B) (www.ti.com/.../getliterature.tsp for a discussion and examples of the reach vs. signalling rate for some types of cables to get an idea.
    Ultimately, you really need to run an experiment with your particular media and other specific conditions (signalling rate, noise, etc.) and check resulting eye diagram.
