Electronic Frequency Synthesizers

An electronic frequency synthesizer is an electrical engineering device that creates multiple voltage-controlled oscillators (VCOs) with integer multiples of a reference frequency, the output of an on-board reference oscillator. The 810251AGI-08LF Device is a flexible, low-power frequency synthesizer used to generate multiple programmable clock frequencies or spreading signals in a wide range of applications.

The 810251AGI-08LF Device integrates three PLLs to provide high performance phase/frequency control of three different output frequencies. It supports a variety of different reference crystal frequencies, such as 24MHz, 26MHz, 27MHz and 30MHz. The frequency range and resolution of the output are programmed using internal registers.

810251AGI-08LF Application Fields

The 810251AGI-08LF Device is suitable for a wide range of applications, such as clock frequency synthesis for radio base stations, satellite communications, wireless infrastructure and advanced communication systems. Additionally, it can also be used for radio frequency (RF) signal processing, frequency hopping, and up converting from IF to RF, down converting from RF to IF, and modulation. Additionally, the device can also be used for clock jitter attenuation, clock synchronization, clock and data recovery, and time and phase alignment.

810251AGI-08LF Working Principle

The 810251AGI-08LF device utilizes a phase-locked loop (PLL) for frequency synthesis. The PLL consists of an oscillator, a phase detector, an amplifier, and a low-pass filter. The oscillator produces a reference signal and the phase detector, when provided with two input signals, detects the difference in phase and magnitude between them. The output of the phase detector is amplified, filtered, and input to the oscillator, where it is used to adjust its frequency and phase, while the filtered output maintains a constant phase and frequency between the reference signal and the output of the oscillator. The output of the oscillator is the synthesized frequency that is typically provided by multiple voltage-controlled oscillators (VCOs).

The 810251AGI-08LF device is capable of generating multiple programmable output frequencies, which can be set by writing to the internal registers. The device integrates three PLLs to provide phase/frequency control of up to three output frequencies. It uses an on-board reference crystal to set its reference frequency, and then uses the three PLLs to generate the output frequencies. Additionally, the output frequencies can also be spread out to reduce spurious emissions and eliminate interference between certain frequencies.

Conclusion

The 810251AGI-08LF is a low-power frequency synthesizer designed for a wide range of applications. It is capable of generating multiple output frequencies, which can be programmed via internal registers. Additionally, the output frequencies can be spread out to reduce spurious emissions and eliminate interference between certain frequencies. The device integrates three PLLs to provide high performance phase/frequency control of up to three different output frequencies. This makes it suitable for clock frequency synthesis for radio base stations, satellite communications, wireless infrastructure and advanced communication systems.
