We have a board we designed using the DM368 running the ARM at 432 MHz. When using the component output set to 480p it is working fine. But when I select the video standard as 720p60 using DMAI the output scan rate is incorrect and the HDTV says it's unsupported. I put a scope on the green and the horz scan rate looks to be about 61 usec, which is not even close. Should be about 22 usec, but It's actually pretty close to NTSC which IIRC is 64 usec.
If it wasn't working in 480p mode I would just assume that I haven't setup a PLL to the correct frequency and go exploring in that direction. Does anyone have an idea about this?
