Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers
The PL585-28DC (Digital Clock Generator/PLL Frequency Synthesizer) is a high-performance, clock generator and PLL (Phase Locked Loop) frequency synthesizer, designed for a wide range of applications. It is capable of producing any clock frequency from the crystal frequency (oscillator) through its PLL, and providing accurate, selectable frequency outputs up to 28MHz.
The PL585-28DC offers a wide variety of programmable clock outputs, including divide-by-n, divide-by-2/3, and divide-by-4/5. It is also a true frequency synthesizer, able to accept an input reference frequency, phase lock to it, and generate any number of output frequencies, all tuned to the input reference frequency. The PL585-28DC is capable of generating frequencies up to 28MHz and features a programmable phase detector and a low jitter phase lock loop.
Applications for the PL585-28DC include battery operated mobile devices, data communication systems, servers, clock synthesizer designs, clock distribution and other applications requiring accurate, high performance frequency control and synchronization at up to 28MHz.
The PL585-28DC is designed for easy integration. It is a proven solution for clock generation and synchronization applications, providing excellent performance and reliability in a small, reliable package. The unit has an integrated voltage regulator, oscillator driver and PLL, and requires only a few external components to operate. The PL585-28DC is capable of generating clock outputs with less than 10ppm of jitter.
Features
- Programmable prescaler, with divide-by-n and divide-by-2/3 capabilities.
- Voltage Controlled Oscillator, which can be programmed to any frequency up to 28MHz.
- Phase Lock Loop frequency synthesizer (up to 28MHz).
- Programmable Phase Detector.
- Low jitter performance.
- Integrated voltage regulator, oscillator driver, and PLL.
- Easy integration.
How Does it Work?
At the heart of the PL585-28DC is its programmable prescaler, which allows for both divide-by-n and divide-by-2/3 clock selection. The prescaler output is connected to the VCO (Voltage Controlled Oscillator), which is capable of producing clock frequencies up to 28MHz. The VCO output is connected to the input of the phase detector, which compares the VCO output to the input reference frequency. Based on the comparison, the Phase Detector adjusts the voltage level on the VCO output, thus dynamically changing the clock frequency.
The Phase Detector output is also connected to the PLL loop filter, which determines the loop time constant and narrows the loop bandwidth. The output of the loop filter is connected to the VCO control voltage, which automatically adjusts the VCO frequency. The output of the VCO is then routed back to the phase detector, thus completing the loop.
The PL585-28DC features a variety of programmable features, including the loop time constant, VCO clock frequency, and programmable phase detector. This allows for great flexibility in programming the device to suit a variety of applications. Once programmed, the PL585-28DC is capable of outputting signals that can be used in a wide variety of applications.
Conclusion
The PL585-28DC is a high-performance, clock generator and PLL (Phase Locked Loop) frequency synthesizer. It is designed for a wide range of applications, and is capable of producing any clock frequency from the crystal frequency (oscillator) through its PLL, and providing accurate, selectable frequency outputs up to 28MHz. It features a variety of programmable features, including the loop time constant, VCO clock frequency, and programmable phase detector. The unit is easy to integrate and is a proven solution for clock generation and synchronization applications, providing excellent performance and reliability in a small, reliable package.
