DS90UB948-Q1: AV mute oLDI output characterisitcs

Dongbao Zhou

Part Number: DS90UB948-Q1

Hello,

What are the typical characteristics of DS90UB948-Q1's oLDI outputs if 948 enters AV mute mode?

My colleague told me according to their test, there is no output on D2+/- and D6+/- (including HS/VS/DE), the rest of differential pairs are ok ( PCLK and RGB data only lane).

Could you help confirm?

Thanks

You may see control signals on D2, D6 (HS/VS/DE) but there should be no data.
