Specs on HVX uncompressed out?

Can someone tell me the details/specs about the uncompressed out, like the data rate, bit rate for the 1080p and 720p and slow-mo 720p recording? I assume it stays 4:2:2, doesn't upgrade to 4:4:4 (ya, i know, dumb question, but if it did, I'd wonder if FCP supports 4:4:4 now) . . .

Thanks!

The uncompressed output is analog, not digital, so terms like data rate and 4:4:4 don't apply. Those are digital terms, not analog terms.

The analog equivalence would be megahertz sampling frequency, etc. And no, I don't know what those specs are. My guess is that it is the equivalent of 4:2:2, probably at 8-bit but perhaps 10; the XLH1's HD-SDI is nominally 10 bits but in actuality it's 8-bit, so it would be surprising if the HVX's analog was resolved at deeper depth than the XLH1, especially because the limiting factor in "bit depth" on an analog signal is the noise floor, and converting digital to analog is likely to show a bit more noise than keeping digital in a digital domain would.
