One common problem designers encounter with crystal oscillators is the long start-up time before the circuit is oscillating at its final frequency. At MHz frequencies, this start-up time is typically 10ms. At frequencies below 100kHz, a crystal oscillator may take up to a second to start up. fish euthanasia clove oil
