What's the shortest delay possible with MN3207?

[ElectricDruid]

Yeah, agree about CMOS over the MN3102. The 3102 doesn't have enough oomph to really push the delay lines to short delays/high clock frequencies. If you roll-your-own VCO in CMOS, you can easily overcome those limitations, at the cost of more chips.
It was this problem I was trying to solve with my Flangelicious clock chip, rolling up the LFO and the biphase clock VCO into a single chip by doing it as PIC firmware. Inevitably that throws up other problems and limitations, the most significant being a 500KHz ceiling. Still, I was pleased to have the whole LFO and voltage-controlled clock on a single 8-pin DIP.

Craig Anderton's Hyperflange uses other CMOS (404-something-i-can't-read and 4041Tom

CD4046 VCO and the CD4041 for the clock buffer.

74HC series is a little more beefier than CMOS.  Can't say if it is good enough through.

Very nice modern solution.  The micros these days have plenty of drive.
