Yep! That’s my source for thatI switched many years ago from Sinar multi-shot backs with a Sinarcam shutter on a Sinar p2 to an Imacon multi-shot back. I remounted the lenses into Rollei electronic shutters with the Rollei Lens Control S. Rollei offered an excellent solution and had the fastest top speed of the available options at 1/500.
Here's what Eric Hiss at Rolleiflex USA has to say about the Rollei and Phase One shutter connection:
HS 1000 Electronic Shutter Rolleiflex DHW USB controlled shutter Copal 0
In 2014/2015 DHW (Rolleiflex) designed and built a new electronic shutter to replace their venerable Rollei electronic shutters using a microchip controller which operates via USB. These they had working at 1/1000th speeds and controlled via USB. I was sent this one unit to look at. It's a working prototype, but no software really exists for it. I sent this to a tech for phase one via digital back dealers to look at around that time and the IP for these was later purchased by Phase One. It seems a lot of it went into Phase One's newly introduced electronic shutters. This shutter is functional but you would be on your own trying to get it to work. I'm selling it more as a very collectible item, I actually only know of two pieces every being made, and as such an interesting part of Rollei History. Rolleiflex has been at the forefront of imaging technology many times, including development of Medium format digital backs in the 1990's. Much of what they have developed has found its way into cameras from other brands.

What’s interesting is that could mean there is actually a solid link between the sinar eshutter, rollei solution, and phase one. Sinar and Rollei collaborated on the Hy6, the firmware of which is definitely used as well in the Sinar M - the display is exactly the same as the hy6!!! There are references in the headers from the sinar M firmware updater to the “rollei af module”. So the CMV/CAB shutters might also be related as the Sinar M can manage those too. Or not!
Rollei and phase one actually worked together a lot too and built some aerial cameras using the 6000 series lenses and later the electronic shutters combined with p series and iq series backs in a tiny package:
