Deascription
This module can directly output the vibration frequency and supports three different active vibration package. It is suitable for most of the vibration products.
The active crystal oscillator has 4 pins which is a complete oscillator. In addition to the quartz crystal, there are transistors and RC components. The active crystal oscillator does not require the DSP's internal oscillator. The signal quality is good, stable, and the connection method is relatively simple (mainly to do the power wave, usually using a PI filter network consisting of a capacitor and an inductor, and the output uses a small resistance. The value of the resistance filter, the signal can), does not require complicated configuration circuit.
Active crystal oscillators have relatively poor flexibility and relatively high prices relative to passive crystal oscillators and active crystal oscillators. Its signal level is fixed, need to choose the appropriate output level, for timing applications sensitive applications, or active crystal is good, so you can choose a more precise crystal, or even high-grade temperature, degree of compensation crystal.
