Default 15.7KHz RGBS / RGBHV -> SDI, single chip solution?

Does anybody know of an easily available IC (digikey,etc) that can convert RGBHV or RGBS video at 15.7KHz to SDI?

Would it be worth your while to build the convertor? I know the boxes are $$$ because we have a lot of SDI convertors at work. But there is some cheap stuff out of China that works OK. Mostly is goes from HDMI to HDSDI, but there is some YUV to SDI stuff around. Check eBay.

Are you trying to go VGA to SDI. What's your source?

Yes I'm trying to go VGA RGBHV or RGBS at 15.7KHz (240p) to SD SDI.

I don't think I've ever seen that. Just YUV to SDI, since they are the same color space. Woudn't the RGBHV would need to be converted to the YUV color space before it became SDI. So maybe 2 chips?

Yes so were right, but was looking for the "one chip" solution, I suppose it doesn't exist.

What about YUV to SDI then, any recommendations?

Since I buy them for work, I have a budget and don't need to DIY. Generally we buy the Black Magic stuff for single box and it works well. But there are converter boxes on eBay for cheap. Probably cheaper than you can build one.
