Other Parts Discussed in Thread: SN65DSI84
Hi,
Our use case is to convert video of resolution 1920x1080 (@60 fps) from Single DSI to Dual LVDS. We are seeing that using SN65DSI85 is incompatible with our LED Input format requirement.
Below is the Comparison we have done,
We are comparing our output data format of SN65DSI85 with our LED supported LVDS input. While observing data format, We have found that Dual-Link LVDS output is not compatible with the LED's input we have chosen.
Below Image 1 shows LED's Input Data & Image 2 shows SN65DSI85 chips's Dual-Link Output Data.
Image 1 : LED Input Data Format
Image 2 : SN65DSI85 Dual Link Output Data
From the above Images What we have concluded is
1. In LED Input data at A_Y0P/N, Green component has pixel number 0 with Bit 2
2. In SN65DSI85 Output data, at A_Y0P/N, Green component has pixel odd with Bit 0
3. In LED Inout data, at A_Y1P/N, Green Component with Pixel 0 and bit sequence is 7,6,5,4,3
4. In SN65DSI85 Output data, at A_Y1P/N, Green Component with Odd Pixel and bit sequence is 5,4,3,2,1
From the above comparison it seems that using SN65DSI85 is incompatible with our LED Display.
We have few doubt from the above comparison,
1. Is our understanding correct, If not then please help me to get it clear ?
2. Is there any such configuration in SN65DSI85 which allow us to change the Pixel value and it's bits values to match with our LED input requirement ? (As from SN65DSI85 Datasheet, It is written that Dual-Link LVDS has Odd pixels for Channel A and Even Pixels for channel b on Page 16 & 17)
3. If SN65DSI85 will not support such configuration then, Is there any other Part which is best fit for the requirement ?
Thanks & Regards,
Pratik
