Oscillators

An oscillator is an electronic circuit used to generate a repetitive, steady, and periodic signal. Oscillators play an important role in timekeeping systems, radio and television systems, electronic musical instruments, navigation systems, control systems, and many other electronic applications. The XLH730004.915200X oscillator is an example of a modern oscillator used in a variety of applications.

It also features programmable phase-locked loop (PLL) frequency selectivity, synchronization capabilities, and enhanced control interfaces that make it suitable for a wide range of applications that depend on accurate frequency control. The highly integrated components and proven design of this oscillator also reduce its design time.

XLH730004.915200X Working Principle

The XLH730004.915200X oscillator is based on a voltage controlled oscillator (VCO) design, which uses a high-Q piezoelectric crystal resonator to generate a periodic, repetitive, and temperature-compensated electrical signal. The oscillator consists of four main components: a variable frequency active device, a crystal resonator, a control voltage source, and a resistor-programmable frequency control module. The active device is the main element of the oscillator, and is responsible for generating the AC voltage and current signals that drive the crystal resonator. The crystal resonator, in turn, converts the AC electrical energy into mechanical vibrations, which are then converted back into electrical signals.

The control voltage source and the resistor-programmable frequency control module are also important components of the oscillator. The control voltage source provides an adjustable DC reference voltage that is used to control the frequency of the oscillator. The frequency control module uses a combination of pull-up and pull-down resistors to program the frequency of the oscillator, providing a high degree of flexibility for the operating frequency of the oscillator.

When the oscillator is in operation, the frequency is monitored by the control voltage source and the resistors, and the signal frequency is adjusted to maintain a consistent output. The XLH730004.915200X oscillator is designed to provide precision frequency control and highly stable performance in the frequency range of 1 MHz to 150 MHz. This oscillator is ideal for crystal applications such as quartz frequency control circuits, frequency-agile circuits, temperature-compensated crystal oscillators, and bank switching applications.
