Part Number: DS90UB949-Q1

Dear TI Experts,

Now I am using DS90UB926 & DS90UB949 for test, I have one problem needs your help:

if the screen pclk is under 25MHz，Can it possible to use 949 combined with 926?

(From the datasheet of 949,the minimum pclk is 25MHz）

If 949 cannot combined with 926 when the screen pclk is under 25MHz，is their anyway to display the pattern of 926 by the pattern of 949?

No, the device cannot support a pclk under 25MHz.
We do not have any HDMI to RGB interface that takes less that 25MHz pclk.

Dear Charley,
Thank you very much ~~

Another question , from the datasheet of DS90UB940, it can support MIPI CSI-2 output~ I'd like to know can 940 support MIPI DSI output?
I have a display project that needs to use MIPI DSI Interface,can you give me any suggestion?thank you ~

940 cannot support DSI output.
CSI-2 and DSI are two different protocal.
We do not have any DSI output deserializer at the moment.
If DSI is needed, it is possible to have a soc convert either oldi or CSI-2 output to DSI
