DS90UB902Q-Q1: match with DS90UB902Q-Q1

Kevin Xiong

Part Number: DS90UB902Q-Q1
Other Parts Discussed in Thread: DS90UB901Q-Q1,

Hi,

My dashboard's interface is BT656:8/10/12bit, so I select DS90UB902Q-Q1 as deserializer. From the datasheet, the recommended serializer is DS90UB901Q-Q1. But in my application, the serializer may be DS90UB925, DS90UB927 or DS90UB949.

My questions are:

1. Does DS90UB902Q-Q1 only match DS90UB901Q-Q1?

2. Can I use DS90UB925, DS90UB927 or DS90UB949 to match DS90UB902Q-Q1? If not, is there any recommended scheme?

Thanks.

Kevin,

thanks to touch us for 901/2 case. yes, 901/2 can be linked with 92x or 94x family. For your dashboard request, please check the PCLK request, the pair between the ser. and de-ser mentioned in d/s, etc.

best regards,

Steve

Hi Steve,

But from the datasheet, I do NOT find the description that this chip can match 92x or 94x family. Could you please provide the related document to support 92x or 94x family?

Thanks.

Hi Steven,

If the ser must be 92x and the de-ser must be 902. Could you please give me a solution?

Thanks.

Kevin,

sorry the SerDes should be paired based on the link PHY design request. in your case, I would recommend you to select the UB926 as de-ser in dashboard, this device can be compatible with UB92x/94x.

best regards,

Steven
