You will need to install Desktop Video to have the Blackmagic uncompressed 10-bit codec installed on your machine. Grab the latest from here:

Once installed, you should now have an assortment of Blackmagic sequence and export settings in FCP7. Export your sequence using the "Blackmagic HDTV 1080p 23.98 - 10-bit" setting which is the native HyperDeck uncompressed 4:2:2 10-bit QuickTime format.
