The ADF4212BRUZ is a highly integrated, low power reclocking/deskewing Clock Generator/Buffer from Analog Devices. It is used in applications ranging from digital video to clock and data recovery to communications and storage systems. This clock generator provides an effective solution for a wide range of clock generation and buffering applications. It provides a low power, low jitter, and easy-to-use solution for clock generation, clock and data recovery, and deskewing.

The ADF4212BRUZ is a single-chip clock generator designed to provide a low jitter fixed or variable clock output to meet the demanding requirements of modern communications, storage, and video systems. It uses a fixed-frequency crystal to generate its primary clock output, and also provides a second output (variable) that may be programmed to maximize system performance. It is capable of generating an output frequency that is up to two times the frequency of the reference.

The ADF4212BRUZ employs a Phase-Locked Loop (PLL) and a Digital Frequency Synthesizer (DFS) to generate its output clocks. The PLL serves as the basis for the clock generator’s low-jitter, fixed-frequency capability and can be programmed to generate frequencies up to twice the reference frequency. The DFS is used for the variable-frequency, programmable-frequency capabilities and can generate outputs up to four times the reference frequency.

The ADF4212BRUZ is capable of generating a wide range of frequencies from 10kHz to 600MHz, and can be programmed to meet the needs of many different applications. An on-chip loop filter eliminates the need for external components and an integrated voltage-controlled oscillator (VCO) eliminates the need for an external crystal. The output signals can be programmed by the host interface to either fall within the input reference range or to “pitch-roll,” using the PLL and DFS to generate the output signal.

In addition, the device provides a “Deskew” feature, which allows the user to adjust the output signal’s duty cycle and delay in order to compensate for signal skew between signal traces on a printed circuit board. This is a very useful feature for cases where signal integrity is a concern, such as high-speed backplanes and data buses.

The ADF4212BRUZ is an ideal solution for a wide variety of clock generation and buffering applications. It provides a low power, low jitter solution for clock generation, clock and data recovery, and deskewing. It offers an easy-to-use solution for high speed system designs and is available in a range of packages for various applications.
