Introduction

The ADN2813ACPZ-500RL7 is a high-precision crystal-controlled, low-jitter phase-locked loop (PLL) frequency synthesizer designed for use in clock/timing applications. The device can provide frequency multiplication, frequency synthesizer dynamic range, and jitter performance required by clock/timing applications. This combination of features makes the ADN2813ACPZ-500RL7 an ideal choice for all types of clock/timing-related applications, including industrial and communication systems.

Application

The ADN2813ACPZ-500RL7 can be used for a wide range of clock/timing applications, such as local oscillators, PLLs, clock multiplication and clock synchronization. It is suitable for timing applications such as frequency hopping, clock recovery, and synthesizer designs. The device is also suitable for complex frequency applications such as measuring instrumentation, telecommunications, and audio/video systems. The ADN2813ACPZ-500RL7 can also provide a wide frequency range, high speed and low jitter performance, making it ideal for a variety of high-performance applications.

Working Principle

The ADN2813ACPZ-500RL7 uses a differential charge-pump phase-locked loop (DPLL) architecture to achieve fast lock time and a high level of jitter performance. The device utilizes an on-chip crystal as an input reference, which provides superior long-term frequency stability. This input reference is used to generate a spreading sequence, which is then converted to a sinusoidal signal for modulation. The modulated signal is then fed back to the input reference, providing a feedback loop. This feedback loop is used to adjust the frequency of the input reference in order to achieve the desired output frequency.

The ADN2813ACPZ-500RL7 also features an on-chip voltage controlled oscillator (VCO). This VCO is used to generate the output frequency, which is then compared to the input reference frequency by the DPLL. If the two frequencies differ, the DPLL will act to adjust the input reference frequency, through the spreading sequence modulation, in order to bring the output frequency in line with the desired frequency. This adjustment process continues until the two frequencies are equal, at which point the ADN2813ACPZ-500RL7 is said to be locked.

Conclusion

The ADN2813ACPZ-500RL7 is a highly-capable PLL frequency synthesizer designed for clock/timing applications. Its combination of low-jitter performance, dynamic range, and frequency multiplication capability make it an ideal choice for a wide range of applications. Its on-chip crystal and VCO allow it to provide both a high frequency stability and the ability to adjust the output frequency as desired. Its DPLL architecture ensures fast lock time and tight jitter performance, making it an ideal choice for engineering high-performance clock/timing applications.
