AM62A7: Maximum Throughput of DPI

Kevin Peng
Expert 4958 points

Part Number: AM62A7

Tool/software:

Hi TI Experts,

In our AM62A datasheet, we mentioned that the DPI throughput is 2048*1080 @ 60fps, that is around 133M pixel per second.

And we also mentioned that we support up to 165MHz pixel clock support with independent PLL. May I know which number we should take as the maximum limit for the DPI throughput?

Also seeing from the TRM page 213, we mentioned that video output more than 1920*1080 @ 60Hz is not supported. The product of 1920*1080 @ 60Hz is 124M pixel per second.

So which number shall we refer, 124M pixel per second, 133M pixel per second, or 165MHz?

The reason to ask this question is that, customer plans to output the YUV data at 5M @ 30Hz through DPI to another ECU. This theoretically needs our DPI throughput could support 150M pixel per second.

Hence, based on your experience, do you think 5M @ 30Hz output from DPI is supported or not?

Thanks,

Kevin
