I’m looking for an analogue VCO (or PLL), with these characteristics:
- analogue output being a pure sinewave with excellent spectral performance (single harmonic)
- the output sinewave frequency ranging from < 1 Hz to 1 or 2 kHz only
- the possibility to reset the phase to zero with an external trigger ideally
Thus, DDS won't be suitable from my understanding.
Would AD have any such component by any chance?
