Interesting patent indeed. Nothing new in principle for those following the Collins school, but interesting to see how it spreads.

Re: [time-nuts] LTC6957 internal architecture
With all this talk of the LT6957 I'm wondering if there's interest in a re-spin of my frequency divider with one of these at the front end instead.
