This question will no dobt make obvious my lack of understanding of HD video format...you patience is greatly appreciated.
Have a question regarding using the AD9380 device, actually its currently on an FPGA development board that I'm looking at.
I have a full HD HD-SDI (1920 x 1080 - 1080psf29,97 or 1080p30) input signal that will be converted to HDMI on the development
board prior to going into the AD9380. The output will be going to a native 1920x1080 LCD panel via RGB to LVDS converter on the
development board. When I read the spec for the AD9380 it says:
"Its 150 MSPS encode rate capability and full power analog bandwidth of 330 MHz supports all HDTV formats (up to 1080p and
FPD resolutions up to SXGA (1280 × 1024 @ 75 Hz)."
In my application I must have full HD (1920x1080) getting to the LCD panel without scaling. What I don't understand is I thought
(maybe that's my problem ) that 1080p was, by definition, 1920x1080. This seems to conflict with the devices' SXGA (1280x1024)
spec. The only thing I can figure, until someone kindly corrects my limited understanding, is that the device can take in 1920x1080
but will only send out 1280x1024 max. However, I think it much more likely I have a misunderstanding rather than the device
having a lower resolution output than input.
Can someone please enlighten me to where I'm wrong.
