Oscillators

Oscillators are electronic circuits which generate a continuous, repeating output signal at a certain frequency. An oscillator is used to generate RF energy from a DC source by alternating the current and voltage. The output of an oscillator can be sinusoidal, square, triangular, or other waveforms, depending on the design and various components used. A wide range of applications is possible, from low frequency to very high frequency. Oscillators are used in many electronic devices, such as radios, television sets, sound systems, computers, and various other types of electronic equipment.

Working Principle of ASGTX-D-38.880MHZ-2-T2 Oscillator

The ASGTX-D-38.880MHZ-2-T2 oscillator operates using a PLL (Phase-Locked Loop) oscillator circuit. The PLL comprises an input module, a phase detector, a voltage-controlled oscillator (VCO) and a loop filter. When the device is powered on, the input module receives a digital signal which is used to set the desired frequency. The phase detector then compares the phase of the reference signal with the output of the VCO. If they do not match, the loop filter adjusts the voltage of the VCO, changing its frequency until the output of the VCO and the reference signal have an exact match. The output of the VCO is a sine wave of an oscillation frequency, which is controlled by the voltage.
