· The crystal oscillator is a crystal oscillator. Its basic structure is roughly as follows: a thin slice is cut from a quartz crystal at a certain azimuth (referred to as a wafer, a quartz crystal resonator, abbreviated as a quartz crystal or a crystal, a crystal oscillator; and an IC is added inside the package) The crystal components of the oscillating circuit are called crystal oscillators.

Making oscillator selection crystal clear
· Because an LC tank or a ring oscillator has a much lower Q (quality) factor than any quartz crystal or MEMS resonator, you might expect the silicon oscillator to take more energy to keep going. However, it takes only microwatts to maintain the oscillation because the power consumption in oscillators depends on the process and architecture of the PLL and temperaturecompensation .
