The AD9575ARUZLVD is a highly integrated frequency synthesizer optimized for programs such as frequency hopping and spread spectrum. It provides an internal voltage controlled crystal oscillator (VCXO) with an output frequency from 2.5 MHz to 1 GHz, using a single 3.3 V supply. Additionally, it integrates a dual-stage, phase-locked loop (PLL) clock to provide a low phase noise clock output. It also includes a phase frequency detector, an adjustable loop filter, two programmable dividers and two phase-detector input clock channels.

The AD9575ARUZLVD is well suited for use in a variety of communication and data acquisition applications. It is capable of providing a clean signal while operating in noisy conditions. Its combination of low phase noise and low on-chip voltage regulator output makes it an ideal choice for a wide range of applications. In addition, its 1 GHz output frequency range makes it suitable for applications such as frequency hopping. This feature is beneficial since it enables frequency changes to be made quickly, reducing the risk of interference.

The AD9575ARUZLVD works on the principle of operation of a PLL clock. A PLL is a type of closed-loop feedback control system. This closed loop system is composed of two main components: a high frequency oscillator referred to as the reference, and a low frequency oscillator referred to as the feedback signal. The two oscillators are connected to a phase detector which senses the difference between their frequencies by measuring the phase shift between them. The output of the phase detector is then passed through a low-pass filter, which filters out any high frequency components. The filtered signal is then fed back to the reference oscillator, which adjusts its frequency based on the feedback signal.

The AD9575ARUZLVD provides a low-jitter, high-bandwidth output clock, which is generated by internally controlling the VCXO’s frequency and phase. In addition, the PLL is equipped with an adjustable loop filter that allows the loop bandwidth to be set over a wide range; this enables the loop to be tuned to match the expected frequency variation and jitter characteristics of the target application. The PLL also features programmable dividers that can be used to divide the output frequency by integer values. These dividers can be used to generate a variety of clock frequencies for specific applications, enabling the user to customize the AD9575ARUZLVD for their particular needs.

The AD9575ARUZLVD is an ideal solution for applications that require highly reliable and low-jitter clock sources. Its ability to generate multiple clock frequencies, as well as its low phase noise and low on-chip voltage regulator, make it well suited for a variety of communication and data acquisition applications. Additionally, its wide frequency tuning range makes it suitable for frequency hopping applications. As such, the AD9575ARUZLVD has the capability to provide reliable, low-jitter clock signals for a variety of applications.
