Oscillators

An oscillator is a device that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clocks to complex computers and processors. The 520M15IA20M0000 oscillator is used by many devices and works according to a fixed design principle.

Application Field and Working Principle of the 520M15IA20M0000 Oscillator

The 520M15IA20M0000 oscillator is a low-cost, high-performance field programmable oscillator capable of producing precise frequency output signals over a parameterized range of operating conditions. Designed for relays, timers, controllers and other various timer circuitry, this oscillator has dual output modes pushed by a series of internal timers. It can be used in automotive, industrial and medical markets.

The 520M15IA20M0000 oscillator contains a voltage transducer with an L/C oscillator, which produces an AC output voltage with a fixed frequency. A rectifier and filtering circuit transform this AC output to a steady DC output voltage for driving the timer circuitry. The transducer is sensitive to frequency changes due to its temperature or aging effects, and may produce a signal drift over time. In the 520M15IA20M0000, a frequency locking circuit with a reference voltage is used to stabilize the frequency of the output signal.

The frequency locking circuit includes an externally adjustable temperature compensation circuit. It also uses a series of timing circuits, including a Schmitt trigger and on-off circuit, to set the output frequency. The Schmitt triggers within the oscillator output a low-phase or high-phase signal, which in turn drives an off-time (tOFF) or on-time (tON) counter. The on-time/off-time combination adjusts the frequency of the output.

The 520M15IA20M0000 oscillator also incorporates a pulse-width-modulated output circuit, which provide the user with additional flexibility when generating a fixed frequency output. This PWM circuit is enabled by a selectable voltage divider circuit that sets the duty cycle of the output signal. In addition, a programmable waveform-shaping circuit is included which can add a programmable waveform delay and a fixed waveform offset.

The 520M15IA20M0000 oscillator is an ideal choice for applications that require an economical and reliable oscillator solution with adjustable frequency output options. Its adjustable timing, temperature compensation and pulse width-modulation capabilities provide flexibility and stability when driving a variety of timer circuits. This oscillator is an ideal choice for many applications ranging from automotive to medical and communication systems.
