I need to generate low frequency 585.5Hz exactly as part of my project. Is there any crystal or oscillator available? All suggestions are welcome...
Yes, 585.14 would be an integer part. An uP also gives the option to implement a fractional divider, that achieves exact average frequency, but with a jitter. Everything depends on the specification.You can use a 32.768kHz oscillator and then use timer or software delay to generate 585.5Hz
Do you own a pocket calculator? There may be very different opinions what available crystals are, so you'll need to try yourself, I think. Otherwise, I keep my programmable oscillator sugestion. Cardinal has acceptable jitter.Is there any combination with available crystals
