DS90UH948-Q1: Rin+ noise measurement in IVI SerDes

Tool/software:

Hi Team,

According to our ADAS SerDes with PoC architecture, we recommend end user measure the Rin+ following our setup to ensure the environment noise.

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1322099/ds90ub960-q1-where-is-rin-noise-from?tisearch=e2e-sitesearch&keymatch=Rin%2B%20noise#

If we would like to achieve PoC on IVI SerDes, may do you have recommended setup? Our PoC power rating is only 5Watt. 

Regards,

Roy

    Hi Roy,

    Our IVI device portfolio does not have validation testing under PoC configurations, so there is no recommended setup. However, in the past some configurations have shown configurations such as HSD +2 (an HSD connector with 2 additional wires for the voltage).

    While it may be possible for this configuration in STP or Coax mode, I would pay close attention to reducing the amount of interference from the PoC network and ensure that channel specifications are maintained for the FPD-Link frequencies that are intended to use.

    Best,

    Miguel
