The PL580-35QC is a model of a clock synthesizer, which belongs to the category of Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers. It is an adjustable frequency synthesizer that can be used to generate stable and accurate frequency clock signals. The PL580-35QC can be used for a variety of applications requiring precision frequencies.

The PL580-35QC features a wide input frequency range of 2.4 MHz to 35.1 MHz, an adjustable output clock frequency range from 0.25 MHz to 16.7 MHz, an adjustable step size of 2.5 kHz to 20 MHz and a programmable jitter attenuation. This makes the PL580-35QC an ideal choice for many applications.

The main application fields of PL580-35QC are data-processing and computer equipment, communication and instrumentation. It can be used to generate reference clock signals for microprocessors, communications and server systems. This clock synthesizer is capable of providing precise short-term and long-term frequency stability. It also has a programmable jitter attenuation function, which can help to reduce jitter in data transmission.

The working principle of PL580-35QC is based on a Phase Locked Loop (PLL) generator. It is a frequency synthesizer that uses a voltage controlled oscillator (VCO) to generate a signal with a frequency that is adjustable depending on the control voltage. The PLL locks the output frequency of the VCO to the reference frequency. A reference oscillator is used to provide the reference frequency for the PLL.

The PL580-35QC accepts the external reference frequency as its input. The PLL then compares the input frequency to its VCO frequency and generates an error signal. This error signal is then used to control the output frequency of the VCO. As a result, the output frequency of the VCO will always be in phase and synchronized with the input reference frequency.

The reference oscillator of PL580-35QC contains a low-noise voltage regulator and an active low-pass filter. The filter is used to reject spurious signals and noise. This ensures that the output of the reference oscillator is clean and over a wide frequency range stable. The voltage regulators maintain a constant voltage supply for the oscillator and for the VCO.

The PL580-35QC also features an adjustable step size and programmable jitter attenuation. The adjustable step size allows the user to adjust the level of frequency output resolution. The programmable jitter attenuation helps to reduce the jitter in data transmission. This helps to improve data transmission quality and also reduces the power consumption of the system.

In summary, the PL580-35QC is an adjustable frequency synthesizer that can be used to generate stable and accurate frequency clock signals. Its wide input frequency range, adjustable output clock frequency range, adjustable step size and programmable jitter attenuation make it an ideal choice for many applications. Its working principle is based on a PLL generator, which locks the output frequency of the VCO to the reference frequency. Its reference oscillator contains a low-noise voltage regulator and an active low-pass filter. Its adjustable step size and programmable jitter attenuation also contribute to its performance.
