The device is capable of generating multiple output clocks from one reference clock, providing the user with greater flexibility and reliability in the construction of their system. In addition to its versatile clock generator features, the PL502-35QI-R can also function as a frequency synthesizer, phase-locked loop and frequency multiplier.

A common application field of the PL502-35QI-R is in the design of systems utilizing multiple clock sources, such as high speed serial interfaces, telecom systems, and multi-media products. By combining the device\'s clocking features, one can construct systems utilizing multiple clocks derived from a single reference signal, improving system performance and providing a more reliable solution.

Working Principle

At the heart of the PL502-35QI-R is a phase-locked loop (PLL) which allows the device to generate multiple clock frequencies. The PLL utilizes a phase comparator which monitors the phase difference between two signals, and generates an error signal when the phase difference is not zero. This error signal is then used to control a voltage controlled oscillator (VCO), which outputs the Multiple Clock Outputs.

The PLL utilizes two control inputs: the reference signal input and the VCO select input. The reference signal input allows the user to select which signal will be used as the PLL reference. By connecting the appropriate signal to the appropriate reference signal input, the PLL will use the selected signal as it\'s timing reference. The VCO select input is used to select which signal the PLL will use to generate the multiple clock outputs.

In addition to the PLL, the PL502-35QI-R also includes an integrated frequency synthesizer which allows the user to adjust the frequency of the multiple clock outputs. This feature allows the user to precisely adjust the frequency of the multiple clock outputs, providing better accuracy and control over the system’s timing. The frequency synthesizer also allows the user to adjust the clock parameters such as jitter, skew and rise/fall times, again improving system performance and reliability.

Conclusion

The PL502-35QI-R is a versatile integrated circuit designed specifically to provide the user with greater flexibility and reliability in the construction of their system. The device can be used as a clock generator, frequency synthesizer, phase-locked loop, or frequency multiplier, which makes it suitable for a wide range of applications. The device\'s integrated frequency synthesizer also provides the user with greater control over the system’s timing, providing improved accuracy and stability.
