Introduction to PL123E-09HSC

PL123E-09HSC is a high-performance clock/timing device which combines a phase-locked loop (PLL), frequency synthesizer, and clock generator in one package. It is designed to improve system performance and accuracy in clock/timing products such as cellular phones and digital cameras. This design offers a wide frequency range, a low jitter clock output, and low power consumption.

Application Field of PL123E-09HSC

The PL123E-09HSC is suitable for a variety of purposes, including mobile telephony, digital television, mobile gaming, GPS, and automotive applications. It is especially suitable for portable devices due to its low power consumption, small size, and high performance. Its features make it well-suited for applications such as audio, video, imaging, and control systems.

Working Principle of PL123E-09HSC

At the heart of the PL123E-09HSC is its core circuitry, which is a type of PLL combined with frequency synthesizers and a clock generator. This combination of components allows the device to lock the output frequency at the desired low jitter frequency based on the input reference clock. The output frequency is determined by the frequency synthesizers which use fractional-N frequency synthesis techniques to divide the input frequency by a fractional divider. This technique offers a wide range of input frequencies and good performance in terms of jitter, phase noise and power consumption. The PLL is then used to further decrease the jitter and phase noise. The clock generator provides a low jitter and low phase noise clock output. It includes a frequency divider, edge alignment, and jitter attenuators to reduce unwanted peaks and jitter in the output signal.

Conclusion

The Phase Lock Loop (PLL) + Frequency Synthesizer + Clock Generator combination of the PL123E-09HSC makes it an ideal choice for clock/timing applications. This design provides a wide frequency range, low jitter, and low power consumption. It is suitable for applications such as mobile telephony, digital television, and mobile gaming, as well as automotive, GPS, and audio/video applications.
