It is the perfect choice for any application that requires high jitter and low phase noise, such as: - Baseband timing- Synchronization of multiple baseband systems- System clock generation- Data communications- Digital receivers- GPS receivers- Digital audio/video systems- 3G base stations

Working Principle

The PL685-P8-358OC features a synthesizer core that includes a Digital Phase-Locked Loop (DPLL) and deep digital signal-processing techniques to generate low jitter output. The DPLL is a stabilizing closed-loop feedback control system that compares a reference frequency to the generated frequency, and then adjusts the generated frequency to reduce the difference to match the reference frequency. The DPLL output is then digitally filtered and processed to tune the reference signal to the desired jitter level.The input signal can consist of multiple references, such as a quartz oscillator, system clock or external PN sequence. The PL685-P8-358OC muxes the reference signal to derive the desired output frequency. It typically consists of a frequency multiplier, a divider, a prescaler and a programmable divider.In addition, the PL685-P8-358OC has a very low in-band phase noise, the ability to support wide bandwidths and a wide frequency range of 500 kHz to 2.4 GHz. This makes it suitable for a variety of frequency applications, ranging from very low frequency (VLF) transmission to wideband wireless infrastructures.

Conclusion

The PL685-P8-358OC is a precision clock generator with excellent jitter characteristics, small package size and low power consumption. It offers a wide variety of features such as multiple reference inputs, wide bandwidths, high resolution signals and low in-band phase noise. As such, the PL685-P8-358OC is suitable for high jitter and low phase noise applications, making it the perfect choice for a variety of industries such as telecommunications, cellular, broadcasting, and pro-audio.
