It is also ideal for communication interface, base station, computer interface, and microwave modulation. This device is suitable for many applications due to its high output frequency range and very low power consumption.

Working Principle

The NB2308AC3DG operates on a Phase Locked Oscillator (PLL) principle. The device has an input buffer, a phase detector, a voltage-controlled oscillator (VCO), a harmonic frequency multiplier and a programmable frequency divider. The device can accept a sinusoidal input frequency in the range of 50 MHz to 8GHz and the output clock frequency is adjusted by the programmable divider. The PLL passes the incoming frequency through the buffer, which ensures that the signal is always clean and of a consistent level. The incoming signal is then compared to the reference signal from the VCO. The phase detector compares these two signals and generates a voltage that is proportional to their phase difference. The voltage is then used to control the VCO frequency, which is subsequently compared to the input frequency. The frequency of the VCO is increased or decreased until the two signals are locked together in-phase. The locked VCO frequency is then divided down in the frequency divider to yield the output clock.

Conclusion

The NB2308AC3DG is a low power clock generator, PLL and frequency synthesizer designed for high frequency applications. This device features high output frequencies of up to 8 GHz and ultra-low power consumption of 2.5mA.
