[time-nuts] Re: 4096 PLL - how to switch off on-chip VCO

[ed breya]

Gerhard, your info is a little confusing. I see several PLL parts 
mentioned - 4046, 4096, 9046, and 8046. Only the 74LV4046 seems to have 
a datasheet, according to my quick look on line. I can't tell yet if 
these others exist, but if they do, and are supposed to be roughly 
equivalent to the 4046 type architecture, then they should work mostly 
the same.

If the PLL reference is 10 MHz, then you'll naturally get spurs from 
there on out. I doubt the built in VCO portion is doing anything wrong 
if you've inhibited that part of it.
