SN65DSI86: SN65DSI86 eDP source PHY test

John Liu59

Part Number: SN65DSI86

Dear all,

My customer want to do the eDP Source PHY Compliance test to verify if SN65DSI86 can meet the requirement, according to the test method, eDP source need be set in certain ways, so they need us provide the tool/script to get the pattern, rate, swing and pre-emphasis setting, can we provide the relevant materials for the test?

Thanks.

Hello John,

We can provide a customized script based on the selected panel spec. You will need to provide the panel's EDID.

You can use the attached script as a reference.
