AD9523-1BCPZ-REEL7

AD9523-1BCPZ-REEL7 is a highly integrated programmable frequency synthesizer from Analog Devices designed for use in communications and instrumentation applications such as clock distribution, digital signal processing, communications, data converters, and timing applications. The device operates from a single 3.3V power supply, laying the foundation for future-proof designs with low pin count.

The AD 9523-1BCPZ-REEL7 includes a programmable PLL with a wide lock range and wide bandwidth PFD, thereby allowing a wide range of frequencies to be generated. It features a programmable reference input stage, providing highly reliable and low noise clock/timing source. The device has several control registers and allows clock sources to be programmed with resolution of less than 10 parts in 1 million. It is well suited to switch between clock sources in less than 500 ns and provides an asynchronous reset single-cycle prescaler.

AD9523-1BCPZ-REEL7 is optimized for use in a wide range of applications, such as communications, instrumentation, automotive, industrial, telecom, and consumer electronics. It is particularly useful for digital broadcast and multimedia applications requiring jitter-free operation. It is ideal for applications that require several different frequencies, as it can switch from one frequency to another quickly and with no glitches. It can be used in applications that require precision timing, since the reference input stage is programmable and provides highly reliable and low-noise clock/timing sources.

The working principle of the AD9523-1BCPZ-REEL7 is simple but quite effective. The device is able to effectively control the frequency and phase of the output clock signal by using an internal voltage controlled oscillator (VCO) that is controlled by a voltage-to-frequency converter. The VCO is connected to a phase-locked loop (PLL), which regulates the frequency of the VCO by comparing the VCO\'s output signal with the input reference. The PLL is able to adjust the frequency of the VCO so that the output signal is in phase with the reference, and is able to maintain the output frequency at a desired value regardless of changes in the reference signal.

The device is able to effectively control the clock sources by using an internal control register. This register is able to store up to eight different register addresses, allowing the user to easily switch between different clock sources on the fly. The device also provides an asynchronous reset single-cycle prescaler, allowing for quick and glitch-free switching of different clock sources.

The AD9523-1BCPZ-REEL7 is an ideal solution for applications requiring multiple clock sources with high jitter immunity and fast switching. Its programmable PLL and wide lock range, as well as its programmable reference input stage, make it an ideal solution for various clock/timing applications. In addition, its single 3.3V power supply and low-pin count make it an ideal choice for future-proof designs.
