I'm using ADV7393 for encoding NTSC.
CLK : 27Mhz
RGB : 4:4:4
VSYNC : 60hz
HSYNC : 33khz
I generate signals to input of adv7393 but it cannot display.
Should I know additional information?
Do you have one of our evaluation boards for ADV7393?
Yes I do.
I have evaluation board for ADV7393 and ADV7391 both.
Did you refer our scripts for our ADV7393 evaluation board?
ADV739x Design Support Files
Yes I did.
but not many reference for my condition
RGB 16 bit 565 input
and I can't connect ftp server. Server is not answering
Due to the holidays and Analog Devices shutdown, there may be a delay to resolving your problem until next week when our product experts will be back in the office. Sorry for the delay during this period.
The 565 input case is only for SD RGB.
here is no progressive to Interlace conversion in the ADV7393.
The CLK input in this mode must be 13.5MHz - (27MHz would be for 422 input
see page 47 of datasheet -
16-Bit 4:4:4 RGB Mode
I made a mistake in my previous post.
in RGB 565 16-but input mode - clock should in fact be 27MHz.
It's the video data that then updates at half the clock rate - 13.5MHz.
