The 527R-02LFT is a high performance frequency synthesizer used in the field of clock/timing. The device can generate output frequencies up to 400 MHz and provide clean output signals without any harmonics. It is a versatile device that can be used in many different applications, including clock data recovery, broadcasting, military, and test & measurement applications. Additionally, the device features a wide array of features such as power down and reset control, adjustable rise and fall times, current limiting, and adjustable frequency divider ratio.

The working principle of the 527R-02LFT is based on a phase-locked loop (PLL). A PLL is a feedback system consisting of multiple components including a reference oscillator, phase detector, voltage-controlled oscillator, and a low-pass filter. The reference oscillator generates an input signal which is used to compare the phase of the input frequency to the output frequency from the voltage-controlled oscillator. If the phase of the two signals do not match, the phase detector will output a difference voltage which is then amplified and used to control the voltage-controlled oscillator, which will then generate an output signal with the same frequency as the input signal.

The output of the 527R-02LFT is an integer frequency multiple of the reference oscillator frequency, with frequencies up to 400 MHz achievable when using a 10-MHz reference oscillator. The device also features a wide operating frequency range covering all major broadcast bands, while the input voltage range can be adjusted using an external resistor divider network to support frequencies from 21 to 1000 MHz, and it has a wide lock range of greater than +/- 1 MHz.

The 527R-02LFT is a very useful device in the field of clock/timing, as it provides high performance and a wide range of features. It can be used in a variety of applications, such as data recovery, broadcasting, military, and test and measurement. With its stable output frequency and adjustable rise and fall times, current limiting, and adjustable frequency divider ratio, the 527R-02LFT can easily be integrated into existing systems, providing a reliable and accurate method for frequency synthesis.
