Hello,

Please tell me about the data rate at the following case.

- 60fps 1920 x 1200 at 24-bit --> OK (I confirmed by data sheet)

- 120fps 1280 x 960 at 24-bit --> Please let me know.

Best Regards,

Hello,

All DSI8x devices support a LVDS Output Clock Range (pixel clock) of 25 MHz to 154 MHz.

The pixel clock for a resolution of 1920 x 1200 at 60 Hz ( REDUCED BLANKING) is 154 MHz, in the other hand, for a resolution of 1920 x 1200 at 120 Hz (REDUCED BLANKING) the pixel clock is 317 Mhz, therefore, is this configuration is not supported by the SN65DSI8x.

Regards,
Joel

Joel san,

Thank you for your reply.
Let me ask you one more thing.

1920 x 1200 at 60Hz (Reduced Branking) is 154MHz --> support
1920 x 1200 at 120Hz (Reduced Blanking) is 317MHz --> not support
Thank you, I understand it.

Then, what about this case; 1280 x 960 at 120Hz (Reduced Blanking) ?
I assume it is impossible to support because 1280 x 1024 at 60Hz is 108MHz, at 120MHz is 216MHz.

Thank you.
Best Regards,

Fujikawa-san,

Your assumption is correct, that is not supported.
