DLPC3433: DLPC3433 DSI Heat and Timings Issue

Part Number: DLPC3433

Tool/software:

Hello, 

I have a custom projector we are designing that uses the DLPC3433 and connects to the image source via DSI signal. 

As reported elsewhere on the TI forums, if the DLPC3433 goes to higher temperature (but still within range), the image starts to have problems. 

Here are other posts about this issue: 

  1. Post #1 - e2e.ti.com/.../dlpc3433-when-the-temperature-is-higher-than-60-c-the-noisy-screen-happens
  2. Post #2 - https://e2echina.ti.com/support/dlp/f/dlp-products-forum/175301/dlpc3433

In both posts, I can't see how they resolved the issue.


Our current DSI settings are the following: 
```

Clock = 117MHz
hdisplay = 1280 cycles
hfrontporch = 360 cycles
hsync = 90 cycles
hbackporch = 362 cycles
vdisplay = 720 lines
vfrontporch = 100 lines
vsync = 12 lines
vbackporch = 100 lines

```

Does someone know if or how this issue can be improved or resolved? 

This is a very important issue to us. Thank you!
