Working Principle of SIT1602BCB7-18S

The SIT1602BCB7-18S programmable oscillator uses fractional-N technology to output signals with low jitter and high frequency stability. It consists of a system logic, frequency synthesizer, and a built-in crystal. The system logic is responsible for initial setup, OTP (One-Time Programmable) code, output signal frequency selection and the LCD screen for displaying information.

The frequency synthesizer works by dividing the frequency of the signal from the crystal oscillator by a specific integer value. The frequency stability of the signal can be further improved by selecting a higher-quality reference clock. The quartz crystal oscillator on the SIT1602BCB7-18S works in combination with a phase-locked loop (PLL) circuit to keep the output signal frequency stable even when the temperature and voltage vary.

Conclusion

In conclusion, SIT1602BCB7-18S is a programmable oscillator designed for various industrial, consumer and communications applications. Its small size, low power consumption and high precision make it a popular choice for many applications. Its working principle is based on a frequency synthesizer, a quartz crystal oscillator and a phase-locked loop circuit, which together ensure that the oscillator maintains frequency stability even when temperature and voltage levels change.
