Oscillators are electronic components that produce a signal with a repeating waveform, or oscillation, most often of a sine or a square wave, from an electrical current or voltage source. The ASCO2-1.8432MHZ-LB-T3 oscillator is one such device, designed to provide a high stability square wave output at a frequency of 1.8432 MHz. This article will look at this oscillator\'s application field and explain its basic working principle.

Application Field

The ASCO2-1.8432MHz-LB-T3 oscillator is designed for use in electronic equipment requiring a signal with a constant frequency and minimum frequency drifts over variations in temperature and other environmental factors. Typical applications where this oscillator can be used include telecommunication and data transmission systems, wireless systems, and computer motherboards.

The device\'s low output jitter and high accuracy also make it suitable for a variety of timing control applications, including precise interval timing, generating interrupts for microprocessor applications, and frequency division for precise clock signals. It is also suitable for use in signal synthesis and conditioning 2 systems, due to its wide temperature range and high accuracy.

Working Principle

The ASCO2-1.8432MHz-LB-T3 oscillator is based on a quartz crystal and operates on the fundamental principle of temperature stability of quartz crystal oscillators. A quartz crystal is an accurate frequency control element which has an extremely temperature coefficient, providing excellent frequency stability and accuracy over a wide range of temperatures.

The quartz crystal in the oscillator is brought to the desired frequency by using an internal temperature-compensated voltage-controlled crystal oscillator (VCXO). The VCXO uses a low-noise oscillator circuit to provide a temperature-stable output signal. This signal is then combined with an external device, such as a frequency counter, to ensure that the crystal remains at its desired frequency.

The resulting output signal is then filtered and amplified with an on-chip amplifier to produce a low-jitter square wave output at a frequency of 1.8432MHZ. The output frequency is further stabilized by using a PLL circuit to continuously monitor and adjust the quartz crystal frequency.

The ASCO2-1.8432MHz-LB-T3 oscillator is a reliable and accurate frequency control device with a wide variety of applications. Its wide temperature range and low output jitter make it an ideal choice for timing control and signal synthesis applications. Its accuracy over temperature variations also ensure that it will provide quality performance in a range of temperature controlled environments.
