Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers is a signal processing technology used to generate and control an output frequency by deriving it from a starting frequency, with or without the use of multiple stages and feedback loops for signal conditioning. The process typically requires electronic components such as multipliers, dividers, phase detectors, low-pass filters, variable frequency oscillators and comparators. The use of such signal processing technologies can result in stable controlled frequency signals with low phase noise and jitter that can be used for a variety of electronic applications.

The PL500-16SI-R is a frequency synthesizer designed to generate and control an output frequency based on a starting frequency. It is capable of operating from 50MHz to 250MHz and offers up to 16 selectable frequencies with a tuning accuracy of 0.1ppm to 100ppm. The PL500-16SI-R can also be used in conjunction with standard input stages to generate clocks of arbitrary frequencies and give them the same accuracy of 0.1ppm to 100ppm.

The PL500-16SI-R is built around a serial programmable PLL core that makes use of a highly integrated fractional-N counter. This counter allows for more accurate adjustment of output frequencies as it allows for fractional-N ratios, which are not achievable with most standard integer-N setup. The PLL also features an integrated low-noise low-phase modifier path that can be used to condition the output signal. Additionally, the synthesizer offers a wide range of voltages and bandwidths, making it suitable for many applications.

The PL500-16SI-R is typically used in applications requiring a stable clock signal. It can be used to generate and adjust any frequency within its range with a high degree of accuracy. For example, it could be used to create a synchronous clock signal for digital video cameras, or a precise frequency to generate a stable output for radio transmitters. It could also be used to create stable clock signals for FPGAs or low-noise clocks in satellite communications systems.

The operating principle of the PL500-16SI-R is based on a feedback loop. This loop is comprised of an input section, a voltage-controlled oscillator (VCO), phase/frequency detector, loop filter and a frequency divider. The input section receives the reference frequency which is then multiplied by the VCO. The output of the VCO is then compared to the frequency of the input in order to make any necessary adjustments in order to make the output frequency match that of the reference. The feedback loop is able to administer more precise adjustments due to the fractional-N ratio.

The PL500-16SI-R is a highly reliable frequency synthesizer with a wide variety of both input and output frequencies that it can generate. Its robust design and multiple adjustable parameters make it suitable for many different applications. It has the ability to generate stable frequencies with low phase noise and jitter, making it a great choice for applications requiring an accurate and reliable clock signal.
