Oscillators

An oscillator is an electronic circuit 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 various systems to generate periodic signals for timekeeping, clock generation, and control signals. In particular, the 7XA2572002 oscillator is a high-performance, micro-sized, low-cost, temperature-compensated oscillator (TCXO) that provides a highly stable output frequency over a wide temperature range.

7XA2572002 Application Field

The 7XA2572002 oscillator has 5 selectable clock frequencies between 16.12MHz and 24.08MHz. This micro-sized 0.25mm quartz oscillator is designed for radio applications in devices such as cellular phones, portable audio devices, digital cameras, and multi-band/multi-standard cellular phones. It can be used for a variety of applications such as Wireless LANs (WLANs), Bluetooth, GPS receivers, digital cordless telephone (DCT), CATV, and broadcast television (BS). It has a stainless steel housing and a quartz crystal element that provide superior protection against vibration, shock, and ESD. The 7XA2572002 is designed to be used in size-constrained applications with minimal installation space due to its ultra-small dimensions (0.25mm).

7XA2572002 Working Principle

The 7XA2572002 oscillator operates on a crystal piezoelectric principle. It is constructed with a quartz crystal element and two electrodes on either side of the crystal. When an AC voltage of the proper frequency is applied to the electrodes, the crystal responds by vibrating. This vibration produces a second AC voltage of the same frequency as the applied signal and at a given amplitude. This phenomenon is known as resonance and is used as the basis for oscillators that require a precise and stable frequency.

The 7XA2572002 oscillator features a jitter of 10ps RMS and an aging rate of 0.5ppm/year. Temperature-compensated quartz oscillators can regulate the frequency of the generated signal in response to changes in temperature. The oscillator also utilizes a linear compensation circuit which enables the output frequency to remain stable over temperature changes. As a result, the 7XA2572002 is able to provide superior frequency stability over a wide range of temperatures.

The 7XA2572002 oscillator is highly suitable for use in small electronics applications such as cellular phones and portable audio devices as it offers excellent performance and superior accuracy. It is easy to install and requires minimal space due to its small size. The 7XA2572002 also offers excellent noise reduction capabilities and its output signal can be easily adjusted according to the needs of the application.
