I need a ~70MHz oscillator with low frequency drift (less than 1%) over a wide temperature range (10°C to 50°C).
I dont have any experience with oscillators, so I have no idea which type of oscillator I should use:
- Colpitts Oscillator
- PLL Clock multiplier (e.g. ICS501)
- Crystal oscillator (e.g. this one here)
- Silicon oscillator (e.g. LTC6903)
I have access to a microcontroller, so I think the simplest solution will be just generating a clock signal and then multiplying it by using a PLL?
I dont care about the wave form, and I dont need to adjust the frequency -- fixed frequency is fine.
