I'm trying to configure the 7431EVB (EVAL-ADV734XEBZ) to work with SMPTE274M 1080I@50Hz.
In the ADV Register Control 6.04 i run the script ADV7403- HD only with SDR EAV/SAV 1080I60 YPbPr In, 20bit 422out. After running this script i can see 1080I60 in the output monitor as expected.
After that i manually chnage the following registers in order to change to 50Hz according to AD application note for AD7403 (Component Processor nonstandard video foramts):
1. 0x87 PLL_DIV_MAN_EN = '1'
2. 0x87,0x88 PLL_DIV_RATIO[11:0] = A50 (hex)
3. 0x8A VCO_RANGE_MAN = '1'
4, 0x8A VCO_RANGE[1:0] = "10"
5. 0x8F, 0x90 FR_LL[11:0] = 3C0 9hex)
1. 0x30 ED/HD INPUT MODE = 74 (hex)
i connect the SMPTE274M 1080I@50Hz video from a standard bar genrator to the EVB and i don't see any video in the monitor. If i bypass the EVB and connect the bar genrator dirctly to the monitor i see the correct picture so the bar genrator and monitor both support this format.
