Part Number: DS90UB941AS-Q1
Other Parts Discussed in Thread: DS90UB948-Q1,

Hi,

1. Is DS90UH series incompatible with DS90UB series, must DS90UB correspond to DS90UB series, and DS90UH series correspond to DS90UH series?

2. Does each link of DS90UB941AS-Q1 support 1920*1080P60Hz, that is, one DS90UB948-Q1 is connected to the corresponding de-serializer of each link,

can it drive two 1920*1080P60Hz LCD screens, or can it only drive 1920*720P60Hz LCD screens?

thanks.

    Hello Wu,

    1. UH and UB devices are compatible but if you want to use HDCP functionality, then you must have UH on both sides. If you are not using HDCP then you can mix UH and UB. 

    2. 941AS can not support 2x1080p screens because the pixel clock requirement is too high. Each channel can support maximum of 105 MHz which is suitable for 1920x720p60

    Best Regards,

    Casey
