THS7372: Circuit test issues

Part Number: THS7372

Tool/software:

Hi Team

My customer has a case that uses the (THS7372IPWR) VGA video signal, but the wiring in the VGA board is long, and the display brightness appears darker.
Is there any VGA video signal driver enhancement solution you can recommend to us?

Thanks,

Boyan

    Hello Boyan,

    Could you share details of the customer schematic and PCB layout?  Proper termination will help with VGA signaling.  Would your customer consider additional video amplifiers?

    Until I know more about the customer system I cannot recommend more steps to assist.  Brightness/luminance is carried alongside the first channel, Y', which is documented in the Application Information section of THS7372.  It could be a problem with only this channel.  

    Best,

    Alec
