i have tried almost everything: check fixed values, checked R_Ext. I2C main-address 0x94=0: pll not locked. I've no idea, what I could do further
What video source and format are you using? What script are you writing into the part?
What voltage do you see on the TMDS lines going into the ADV7513?
all video inputs have CMOS 3.3V voltage level.
a fpga generates testpattern
Both videoformats are recognized by the ADV7513, but
I dumped the main-register adv7513-register-dump.log, some read only register show not the
How do you know it recognizes the format? Are you seeing the correct VID code recognized?
Was there a script you use as a starting point for what you programmed the part with?
i attached the main register dump. the register 3C, 3D, 3E show clearly 1080i 50Hz recognized. what script? Its an embedded design with an 16bit microcontroller. the initialization of the ADV7513 follows the suggestions made in the ADV7513 programming guide "ADV7513_Programming_Guide_Rev_0.pdf".
I'm trying to get some scripts posted for this part
I see the dump.. but what are you actually writing (versus dump values that are at default). From the dump I see at least one issue: 0xBA - you are setting clock delay to -1.2ns-- do you mean no delay? Also, bit 4 must be a 1 for internal keys so I'd expect to see 0xE0 here. This could be the problem.
The other possibility is hardware: Is your PVDD isolated from the other supplies as shown in Figure 21 of the hardware user guide or is it tied to them?
the dump read back the register values after initialization. why is it important to know which register were written? important is, what they are after initilization.
the bits you mention, i have already modified. 0 delay, hdcp on/off.
power is designed as shown in the adv7513 hardware design guide.
in hdmi mode i get an output, but at 32MHz pixel-clock, thats why the monitor says 862x540@50Hz. it should be 74.25Mhz pixel-clock and 1080i 50Hz
I need to know only what you wrote so I can compare it against scripts which make assumptions about the rest of the registers being at default. It's about saving time-- if I have to go through an entire dump when you could just tell me what you wrote then it's going to be a lower priority task.
its the mininmal setup, shown in the programming guide:
0x41 0x10 -- power-up
Fixed registers that must be set on power up
Set up the video input mode
0x15 0x00 -- Video Format ID RGB444
0x16 0x34 -- color depth 8bit, input stale 2
0x17 0x02 -- Aspect ratio of input video 16x9
Set up the video output mode
0x16 0x34 -- Output Format 4:4:4
0x18 0x06 -- CSC disabled
0xAF 0x16 -- hdcp disabled, hdmi mode
thanks for your help.
the pcb designer checked the grounding of the adv7513. the gnd-pads are not soldered ...
Yep.. that would do it. Thanks for letting us know!
