416F40025CST Application Field and Working Principle

Crystal oscillators are widely used in today’s electronics industry; they are widely used in digital and analog applications as frequency references, clock sources, pulse generators and high-resolution timing circuits. The specific crystal oscillator used is the 416F40025CST, which is a low cost, dual-purpose frequency-controlled oscillator with a low mass, designed to operate in both oscillator and frequency synthesizer applications.

The 416F40025CST is a fundamental, surface-mounted crystal oscillator with a low profile of only 0.402inches. It can operate in either a series (VCO) or parallel (PLL) mode. It also has a wide frequency range of 10.7 MHz to 400 MHz, with a typical output frequency accuracy of ±25 ppm. Additionally, it has an integrated output buffer which can drive up to three TTL gates with a supply voltage of 4.5 VDC to 5.5 VDC.

In series mode, the 416F40025CST oscillator uses an external crystal to generate its frequency reference. The crystal is connected to the oscillator\'s input pins and acts as a frequency-selective tank circuit. When a frequency-selective tank circuit is properly tuned, it will resonate at a specific frequency and reject all other frequencies. The 416F40025CST oscillator uses this resonance to generate a frequency reference which is then used to drive the integrated buffer. The oscillator\'s output is the frequency reference multiplied by the value of the capacitors surrounding the crystal. This provides an output frequency with very little inherent jitter or noise.

In parallel mode, the 416F40025CST oscillator uses its own internal oscillator in conjunction with an external VCO. The frequency reference is extracted from the VCO and then multiplied by an internal frequency-selective tank circuit. This gives the oscillator an output frequency which is much less susceptible to noise and jitter than series operation.

The 416F40025CST oscillator is very versatile and can be used in a variety of applications. It is commonly used in frequency synthesis, clock synchronization, frequency-hopping, digital communication protocols, embedded system timers, and digital logic sequencing. Its wide frequency range and low mass make it ideal for applications where a very high frequency reference and low jitter are required.

Overall, the 416F40025CST is a low-cost, dual-purpose crystal oscillator with a low mass and wide frequency range. Its wide range of applications, combined with its accuracy and low jitter rate, make it an excellent choice for a variety of electronic projects.
