Oscillators are circuits or electronic devices which produce regular, periodic electrical signals that oscillate between two nominal levels.One of the most common forms of oscillator is the alternating-current oscillator, frequently referred to as an RC oscillator due to its switches being composed of a resistor and a capacitor. The 7Q24072001 is a highly stable, low power, frequency-selectable RC oscillator, capable of operating at frequencies from 1000 Hz to over 100 kHz. It is one of the most widely employed types of oscillators in the industry due to its reliability, compatibility, and low price.

Application

The 7Q24072001 is used in many different types of applications, primarily as part of an electronic circuit. Its frequency selectable functions make it suitable for radio frequency (RF) communication applications, including radar, radio receivers, and transmission systems. It can also be integrated into audio applications, such as digital sound systems. Finally, the oscillator is used for frequency locking and time measurement in automatic control systems.

Working Principle

The 7Q24072001 works on the basis of a voltage-controlled oscillator (VCO) circuit. Its frequency-selectable feature is enabled by a highly stable quartz crystal, which is used to regulate the frequency output of the oscillator. Its core components include a quartz crystal, a resistor, a capacitor, and two controllable switches. The resistor and capacitor form the timing network, which is loaded with the quartz crystal to create a frequency-selectable VCO.

The VCO is set to a starting frequency by controlling the switches with voltage signals. These signals cause the capacitor to be charged and discharged at a fixed rate, which defines the oscillation frequency of the VCO. Any changes in the frequency can be achieved by adjusting the resistor value or the capacitance of the capacitor.
