AD9551BCPZ-REEL7 Application Field and Working Principle

The AD9551BCPZ-REEL7 is a high performance, low power, Frequency Synthesizer device from Analog Devices. It is suitable for use in a wide range of Clock/Timing applications such as clock generation, PLLs, frequency synthesizers, etc. The device performs both frequency synthesis and clocking while consuming minimal power.

The AD9551BCPZ-REEL7 incorporates a sophisticated digital phase-locked loop (PLL) controller and digital frequency synthesizer to reduce the power consumption and complexity associated with clocking digital systems. This architecture eliminates the need for external components while allowing precise frequency adjustment in response to externally supplied reference clock. The PLL can be tuned to deliver precise single frequency outputs as well as multiple-band frequencies.

The device features a programmable divide-by-N divider, with a resolution of up to twelve bits, that produces a precise integer division of the reference frequency. The divider output is used as the reference for the PLL controller, which is then used to generate the precise output frequency. In addition, the device also offers an automatic power-down feature that reduces power consumption when low-frequency operation is needed.

The output frequency range of the AD9551BCPZ-REEL7 can be set from 125kHz to 245MHz when combining the 12-bit divider and 9-bit output divider capabilities. The device also offers 8-bit input reference frequency range of 1.2MHz to 240MHz. The output frequency range and division capabilities make the device especially suitable for a wide range of digital applications and systems.

The AD9551BCPZ-REEL7 also features a wide operating temperature range of -40°C to +85°C and four power options, all in an 8-lead Pb-free package, making it an ideal choice for cost- and space- constrained, high-speed digital systems.

The device has been designed to operate with minimal power consumption, and is equipped with several power-saving features. The most notable of these is the programmable divider, which reduces the the power required for multi-frequency outputs, as well as the automatic power-down feature, which reduces power consumption when not actively generating output. Additionally, the device offers a sleep mode and a wake-up timer which can be configured to conserve power.

The AD9551BCPZ-REEL7 is specifically designed for high speed digital systems and offers a cost-effective solution for Clock/Timing applications including clock generation, PLLs, and frequency synthesizers. Its integrated PLL architecture and low power consumption make it an attractive solution for these applications. The wide operating temperature range and extensive feature set of the device offer high performance and reliability for a variety of applications.
