The 8T49N285A-999NLGI (hereinafter referred to as the 8T49) is a precision clock generator and frequency synthesizer, designed to provide low-noise precise timing and frequency control solutions in a wide range of applications. It is suitable for use in clocks and timing systems, which require precise timing signals, precise clock generation and frequency synthesis. This clock generator and frequency synthesizer is suitable for industrial, military and aerospace applications.

Application Field of 8T49

The 8T49 has been designed to provide a precise and stable clock source for communication networks, digital signal processor (DSP) systems, digital audio systems, jitter and noise reduction systems, motor control systems, and digital synthesizers. It is also suitable for supplying precision timing and frequency signals for high-speed clock systems, often found in military and aerospace applications. Additionally, it is an ideal choice for systems that require high-quality timing and noise reduction solutions, as well as systems that need precise timing and high frequency stability.

Working Principle of 8T49

The 8T49 operates on a principle of fractional-N frequency synthesis (FNFS) which is based on the charge-pump phase-locked loop (PLL) architecture. This means that the output of the 8T49 operates in an oscillating-validation mode which ensures that the oscillator remains in lock with an accurate reference frequency. In FNFS, a clock signal is generated by combining the output of two oscillators : one acting as a reference oscillator, and the other acting as a key or control oscillator. The 8T49 can generate frequencies in the range of 8kHz to 40MHz, and it is capable of producing fractional-N frequencies with a resolution of 1MHz. The 8T49 has a low jitter of 100fs and a frequency stability of 1ppm.

Conclusion

The 8T49 is an excellent and reliable solution for various clock and timing requirements, especially in industrial, military, and aerospace applications. Its fractional-N frequency synthesis architecture allows it to generate frequencies with a resolution of 1MHz, enabling it to produce precise and stable clock sources. Furthermore, its low jitter and frequency stability make it suitable for systems that require high-precision timing solutions. Thus, the 8T49 is an ideal choice for clocks and timing systems that require precise and reliable ticking.
