Since injection locking is possible when the ratio of the 2 frequencies
involved is a rational number, a 16 MHz oscillator can be directly
injection locked to a 10MHz signal without the need for dividers etc.

OK the challenge simple. CD4046 16 MHz vco and div by 8 using a 2 Mhz ref.
Thats pretty easy as they say.
As an alternative and very easy 10 MHz div 2 2MHz X 4 X 2. This requires
BPF but pretty easy also.
Lastly an injection osc. 10 Mhz div to 2 Mhz differentiate and feed to a 16
Mhz osc.
Thats actually the easiest of the approaches.

What's the simplest way to generate 16 MHz from 10 MHz? This will be for
clocking a microcontroller at 16 MHz given 10 MHz (Cs/Rb/GPSDO). Low price
and low parts count is a goal; jitter is not a concern but absolute
long-term phase coherence is a must.
The ICS525 (as in TAPR Clock-Block) is a good candidate but I was
wondering if there's something cheaper, less functional, and maybe not
SSOP. Any suggestions?
Thanks,
