Andrew's pretty spot on. The DeckLink Mini Monitor (non-4K) was released with support added in Desktop Video 9.7.3. This version of Desktop Video included Premiere CS6 support. I don't know, but am doubtful, that the plugin structure for CS5 would have been bundled in that driver. Similarly, The DeckLink Mini Monitor 4K began its support with Desktop Video 10.8. This driver version included support for CC 2014 and CC 2015.
So officially, no, the DeckLink Mini Monitor and DeckLink Mini Monitor 4K would not be a supported hardware option for CS5. The DeckLink Mini Monitor 4K might potentially work with CS6 (unofficially), but I'm not really confident either card will work in CS5 without a test. I don't have an older copy of CS5 to try though.
