The device operates with a power supply of 3.3V and provides a ±2% accuracy with a 0.5 critical damping factor. It is options with two serial ports, two parallel I/O pins, one clock input and one clock output.

Application Fields

The PL585-P8-048OC-R is ideal for applications such as signal synthesis, signal distribution, signal processing and high-speed networking. It is widely applied in the fields of Wi-Fi, LTE, Ethernet, video encoding and decoding, signal processors and imaging.

Working Principle

The PL585-P8-048OC-R operates through a phase-locked loop (PLL) frequency synthesizer architecture. This consists of a Voltage Controlled Oscillator (VCO), a Loop Filter and Control Circuit. The loop filter is the primary element that determines the loop characteristics and the stability of the PLL.The VCO is driven by the output of the loop filter via its control circuit. It converts the output of the loop filter into a frequency signal, which is then output as a clock signal after amplification by the frequency divider.

The input to the PLL are the clock input and the parallel control inputs. The clock input is used to generate a reference frequency, which is the basis for the generation of the output frequency. The parallel control inputs are used to control the frequency and to set the frequency range of the output clock signal.

Conclusion

The PL585-P8-048OC-R is an ideal solution for phase-locked loop frequency synthesizers. It provides excellent accuracy, stability and low jitter while outputting frequencies ranging from 0.45 – 800.0 MHz, making it applicable to many industrial and commercial applications that require the generation of precise clock signals.
