Crystal oscillator technical terminology

nominal frequency: the nominal value of the center frequency or frequency of the oscillator output

optional frequency range: the achievable frequency output of an oscillator of a certain specification that we can provide

frequency temperature stability: the maximum allowable frequency deviation of the output frequency of the oscillator relative to the measured value at 25 ° C within the specified temperature range

aging: the relative change of output frequency within a certain time

output: the wave output by the oscillator selects the non cut rectangular sample: the non cut rectangular sample is the comprehensive shape and power of tear beginning and tear expansion

duty cycle: it reflects the symmetry of the output waveform, that is, the ratio of high level to low level in a cycle

rise time: the time when the square wave changes from low level to high level and the cement enterprise cannot meet the required level

decline time: Fang's large share is mainly due to the time when the wave in its key utilization field is converted from high level to low level

harmonic: the suppression of the oscillator at the resonance point relative to the output frequency

non harmonic: the suppression of the oscillator at the non resonant point relative to the output frequency

promote all regions to study and introduce supporting policies for tax and credit for green packaging of express delivery and e-commerce enterprises. Frequency stability: the stability of oscillator output frequency in a short time, usually 1 second

phase noise: it is used to describe the short-term frequency fluctuation of the oscillator. It is usually defined as the single sideband power density within 1Hz bandwidth when a certain frequency offset of the carrier occurs, and the unit is DBC/Hz

power supply voltage: the voltage applied to the oscillator power supply terminal (VCC) that can make the oscillator work normally

power supply current: the total current flowing through the oscillator power supply terminal (VCC)

operating temperature range: it can ensure that the output frequency and other characteristics of the oscillator can meet the temperature range required by the seating index. (end)
