Hi All of the divide by 2 stuff and the frequency counter on the input would make more sense with a DFF as a mixer. It also might explain the use of a 3V CMOS signal as the “standard input”.
It may all be in an FPGA. One thing missing in the info - can the LO be tuned at all? If not, you will have to be right on whatever frequency it’s set to. Those same de-glitch filters will get you if you aren’t.
