Working Principle of 416F27133ISR

416F27133ISR provides a low-power, wide-range frequency crystal oscillator IC, which includes the frequency divider, phase locked loop (PLL) and VCO (Voltage Controlled Oscillator). According to the program, the crystal frequency is divided into the f1 output and the f2 output.

This device combines the SMD type crystal package with PLL, to provide high output frequency accuracy and lower frequency jitter performance. By connecting the compensation circuit, the TCXO can be used to supply sub-milli second jitter. It is also resistant to temperature variations, by means of an external temperature compensation circuit.

Within the 416F27133ISR, two different frequency dividers are designed for two different output frequencies, namely f1 and f2. The first part of the circuit is the basic frequency divider. This divider divides the crystal frequency by the dividing factor (N1 or N2). This determines the frequency of the first output signal: f1 = N1 × crystal frequency. The second part is the PLL circuit. This is used to introduce extra accuracy into the output frequency. In this case, the correct relationship between two output frequencies is f1 = f2 × N3. The final part of the circuit is the VCO, which is used to control the frequency of the second output signal, f2.

Conclusion

In conclusion, 416F27133ISR is a low-power, wide-range frequency crystal oscillator IC, used in various fields. The core of this IC includes the frequency divider, PLL and VCO. This IC provides high output frequency accuracy and low jitter. It is resistant to temperature variations, by connecting the external temperature compensation circuit.
