Oscillators: 578S260CAT Application Field and Working Principle

Introduction to 578S260CAT

The 578S260CAT is an oscillator, specifically a voltage controlled crystal oscillator (VCXO) designed and manufactured by Fox Electronics. It is part of Fox\'s 578S product series, which are designed for frequency control in cellular telephone infrastructure applications. This particular VCXO has an output frequency of 26.0 MHz and is typically operated from a +5 V supply, though a range of other supply voltages are supported.

Application Field

The 578S260CAT is designed to handle the various demands of cellular telephone infrastructure applications. Its output frequency and accuracy are both suitable for this purpose, and its frequency stability is quite good over temperature. Its low phase noise also makes it particularly suitable for applications where low noise is essential, such as synchronization networks and digital radio.

The 578S260CAT is also well-suited to applications in the industrial, medical, military and aerospace markets. Its compact footprint and low power consumption make it an ideal choice for a wide range of applications, from medical imaging to precision instrumentation.

Working Principle

The 578S260CAT uses a quartz crystal resonator as its frequency-determining element. The crystal resonator is a piezoelectric device that vibrates when supplied with an alternating electric field. The frequency of the oscillations is determined by the physical properties of the crystal, such as its shape and size. Changes in the applied voltage cause the oscillating frequency to change, a process known as frequency control.

The 578S260CAT also includes a number of integrated components, such as amplifiers, flip-flops, and logic elements, which are connected in such a way as to create an oscillator circuit. This oscillator circuit generates an output waveform with a frequency that is determined by the properties of the crystal resonator. The 578S260CAT also contains a voltage-controlled circuit that allows for precise control of the output frequency.

Conclusion

The 578S260CAT is an oscillator designed for frequency control in cellular telephone infrastructure applications. Its output frequency, accuracy, frequency stability, and low phase noise make it suitable for this purpose, as well as a wide range of other applications in the industrial, medical, military, and aerospace markets. The 578S260CAT uses a quartz crystal resonator as its frequency-determining element, and a voltage-controlled circuit to allow for precise control of the output frequency.
