Working Principle

The MC100LVEL39DWR2G is designed around an advanced fractional-N PLL, which enables the circuit to generate highly stable, accurate signals with excellent signal-to-noise ratio (SNR). In a fractional-N PLL, the input frequency is split into two components, one of which is used to create a Phase/Frequency Detector (PFD) signal, and the other to generate a feedback signal. This feedback signal is compared against the PFD signal, and the output frequency is adjusted to match the PFD signal. This approach enables the circuit to precisely control the output signal, offering excellent performance and low power consumption.

The MC100LVEL39DWR2G features an integrated Voltage Controlled Oscillator (VCO) that can be programmed to output frequencies from 20 MHz to 300MHz, providing a wide range of choices for clock synthesizers. The circuit also features an integrated divide-by-4 and divide-by-8 clock divider, offering additional flexibility. The circuit offers low-noise and low-jitter operation, making it suitable for applications where clean and precise signals are required.

Conclusion

The MC100LVEL39DWR2G Clock Generator and Divider integrated circuit is a high-performance, low-power solution designed for clock synthesizers and timing applications. It offers excellent performance, with low noise and jitter, making it suitable for a wide range of applications. It is an excellent choice for designers looking to reduce power consumption while maintaining performance in their designs.
