The 844252AG-04LF is a high-performance clock generator, voltage controlled oscillator (VCO) synthesizer, and clock multiplier integrated circuit. It is used in a variety of applications where a precision, low power, low jitter clock generator is needed.

Applications

The 844252AG-04LF is mostly used in communications systems, such as wireless systems, fiber-optic cable systems, base station controllers, networking systems, storage systems, and test and measurement instruments. It can also be used for industrial process control, time-critical applications, GPS systems, and HDTV broadcasting.

Working Principle

The 844252AG-04LF has an integrated fractional-N synthesizer core, allowing it to generate precision clock signals across a wide frequency range without any external components. It accepts an input frequency from 10 MHz to 800 MHz and is capable of multiplying it up to 8 GHz.

The device features a voltage controlled oscillator (VCO) Synthesizer which enables the device to generate frequency outputs that are not harmonically related to the input frequency, meaning that clock signals generated by the 844252AG-04LF can have frequencies that are not exactly integer multiples of the input frequency.

The 844252AG-04LF also features a low jitter of 800 fs, making it suitable for high-speed clock signals such as in communication systems. It also has a low power consumption of 4 mA.

Conclusion

The 844252AG-04LF is a versatile clock generator, VCO synthesizer, and clock multiplier IC with a wide frequency range, low jitter, and low power consumption. It is suitable for a variety of high-speed applications including communications systems, industrial process control, GPS systems, and HDTV broadcasting.
