Working Principle

The working principle of the ASTMHTD-20.000MHZ-XC-E oscillator can be described as follows. The oscillator contains an amplifier circuit and a feedback circuit, which can generate a stable frequency signal. The amplifier circuit is used to amplify the input signal of the oscillator; the feedback circuit is used to provide phase shifting from the output of the amplifier. When the input signal is in its high state, the output of the amplifier follows the input signal, which then feeds into the feedback circuit. The feedback circuit then uses the signal to adjust the amplifier so that the output of the amplifier is in its low state. This process is repeated and produces a continuous oscillation at a fixed frequency, which is determined by the amplifier and feedback parameters. The output signal of the ASTMHTD-20.000MHZ-XC-E oscillator is a square wave with a frequency of 20MHz. The output levels of the oscillator are TTL and voltage range.
