Feature Benefits

• Ultra-low jitter: 0.4ps RMS Single clock cycle
• Frequency range: 10 -196 MHz
• Integrated loop filter simplifies design
• Fast locking to a variety of standards
• Programmable power down
• Generates low jitter, multiply and divide-by-two clocks

The 844021BGI-01LF clock generator and fan-out buffer provides an incredibly low jitter range and fast locking speed to a variety of standards. The product utilizes sophisticated Clock Perfection™ process which takes clock jitter to a new level.

Working Principle

The 844021BGI-01LF employs a proprietary Clock Perfection™ technique that offers a very low jitter performance (<0.4ps). This process analyzes the clock´s jitter across both the frequency and the time domain, thus supports a broad range of clock frequencies. As the clock is distributed to the outputs, the jitter is equalized, providing a consistent output jitter performance.

The integrated Loop Filter also simplifies external components which can reduce cost and save board space. Moreover, the Loop Filter also enhances jitter performance, making the system close loop faster while remaining in lock.

The product offers a range of programmable power-down modes to ensure optimal energy savings. It also supports a comprehensive set of features: enable, reset, and loop filter enable. Users can also configure the device easliy via I2C.

Conclusion

The 844021BGI-01LF is a highly versatile device designed for low jitter clock generation applications. It offers a wide frequency range and a proprietary Clock Perfection™ process that guarantees a very low jitter. In addition, it has integrated Loop Filter which also helps to reduce cost and simplify design. It is an ideal solution for digital or packet networks, optical line-terminal applications and server and storage backplanes.
