Its exceptional wideband characteristics make it ideal for use in RF designs that require extreme sensitivity and linearity.

The 520M15HT20M0000 oscillator is also used for power supply control, allowing users to accurately time the switching and clocking of the power supply. With the help of this oscillator, users can ensure the proper power supply voltage distribution and power supply response time. The 520M15HT20M0000 oscillator is also used in automotive applications for powertrain, engine control, and safety systems control.

Working principle

The 520M15HT20M0000 oscillator works by using a quartz crystal and a capacitor to create a resonating circuit. The quartz crystal and the capacitor respectively vibrate at a particular frequency, which is determined by the size of the crystal and the capacitance. The oscillator then works by over-stressing the crystal with a varying voltage and creating a frequency-determining circuit, known as an astable multivibrator. The two frequencies generated by the astable multivibrator are then mixed together in a governing circuit, creating an output frequency.

The 520M15HT20M0000 oscillator has a wide frequency range of 0.01 Hz to 5 MHz, which can be programmed via the software interface. The output frequency is controlled by an internal voltage-controlled oscillator (VCO) and an external clock reference. Additionally, the 520M15HT20M0000 can be programmed with an on-chip EEPROM to store and recall frequencies. This makes the 520M15HT20M0000 an ideal choice for applications that require programmed, precise control of oscillation.
