DS90UB926Q-Q1: RGB timing doesn't meet DLPC102 requirement

Part Number: DS90UB926Q-Q1

Hello,

One customer used DS90UB926+DLPC120, he found that the timing of DS90UB926 doesn't meet the DLPC120 because the polarity of HSYNC and VSYNC are opposite, while DLPC120 need the same polarity.

Below is DLPC102 timing requirement:

Hey Kailyn,

You can only switch polarity from The Ser or from the video source. What Serializer are you using here? Some of our Ser are able to switch the polarity like 941AS, but some of the older ones like 925 can't switch the polarity so you'd need to switch the polarity from the video source.

Hi Fadi,

Thank you very much for your reply, he is using the DS90UB925 and I had read the datasheet it is no way to switch the polarity like 941AS.

OK, I asked the customer to switch the video source polarity to try.

Best regards
