16mhz Crystal Oscillator Circuit. The above figure is a 20psc new 16mhz quartz crystal oscillator and it is one kind of crystal oscillators that works with 16mhz frequency. This frequency is often used to keep track of time as in quartz wristwatches to provide a stable clock signal for digital integrated circuits and to stabilize frequencies for radio transmitters.
First off the datasheet says we can use either a crystal oscillator or a ceramic resonator. For ultra high precision needs usb timing long term time keeping rf pll vco driving you may need a crystal or temperate compensated oscillator. It also has automatic amplitude control and frequency drift is also very low due to change in temperature.
The crystal oscillator s output is fed to the system pll as the input refe rence.
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency 1 2 3 this frequency is often used to keep track of time as in quartz wristwatches to provide a stable clock signal for digital integrated circuits and to stabilize frequencies for radio. This is a good match for people building arduino compatibles since the arduino uno is clocked at 16mhz. The above figure is a 20psc new 16mhz quartz crystal oscillator and it is one kind of crystal oscillators that works with 16mhz frequency. The 16 mhz crystal oscillator module is designed to handle off chip crystals that have a frequency of 4œ16 mhz.
