Does anyone have experience with the Averlogic AL250 Video Scan Doubler IC?
Datasheet is here
and Application notes
As far as interfacing to this IC, do think it's out of reach for a beginner? They don't provide a schematic for their evaluation board, but the parts list doesn't look too crazy.
It has I2C control, which should be easily accessed from any microcontroller.
I've got a simple application for the IC, and it would be setup in a fixed configuration mode. There's no need for multiple connectors, multiple display modes, etc. One NTSC input(~15khz), one VGA output(~31khz).
In general, is scan doubling/de-interlacing a hard thing(TM) ? This IC does some fancy things, but would simply sampling one side, buffering, and then outputting the other side generally work?
