Introduction

87946AYILF is a clock generator, phase locked loop (PLL) and frequency synthesizer module which belongs to the clock/timing category. It has a range of applications in electronic systems and it is often used for high speed frequency synthesis in communication systems and for local clocking of other logic devices. In this article, we\'ll discuss the application field and working principle of 87946AYILF.

Application Field

The 87946AYILF is a versatile timing system which is used in a wide range of applications. This includes:

• Control and automation systems
• Communication systems
• Signal processing applications
• Networking applications
• Test and measurement systems
• Data acquisition systems
• Satellite navigation systems
• Computer systems
• Medical instrumentation

• Industrial process control systems

The 87946AYILF is also used in avionics, automotive, entertainment and other industries as a source of frequency synthesis and timing.

Working Principle

The 87946AYILF consists of a main oscillator and a voltage-controlled oscillator (VCO). The main oscillator generates a signal of constant frequency which is fed to the VCO. The VCO then multiplies or divides this signal to produce the desired frequency which is then output from the module. The signal from the main oscillator is also used to generate a voltage controlled phase locked loop (VPL). The VPL helps to stabilize the frequency of the output signal, thereby reducing jitter and drift.The 87946AYILF can be used to generate a variety of frequencies, ranging from 50 kHz to 8 MHz. The frequency can be changed using a digital control signal or an analog voltage. The frequency resolution depends on the clock speed of the module, with the maximum resolution being up to 0.025% of the clock frequency.

Conclusion

The 87946AYILF is a versatile clock generator, phase locked loop (PLL) and frequency synthesizer module. It is used in a wide range of applications, including control and automation systems, communication systems, signal processing, test and measurement systems and satellite navigation systems. The module can be used to generate a variety of frequencies, ranging from 50 kHz to 8 MHz, with a resolution of up to 0.025% of the clock frequency.
