The working principle of the SIT1602BI-11-28E-18.432000E oscillator is based on the principle of mechanical resonance. The oscillator consists of a quartz crystal, an amplifier, and a feedback network. The quartz crystal acts as the resonator, and its voltage is varied by an external voltage (Vc). The amplifier amplifies the input signal, which is then fed back to the crystal by the feedback network.

The feedback network works as a phase sensitive detector, comparing the phase of the amplified signal to the phase of the original signal, and adjusting the voltage at the crystal accordingly. This feedback loop maintains the output frequency at the desired level, and also ensures stable, low-noise phase operation.

Overall, the SIT1602BI-11-28E-18.432000E oscillator is a great solution for the ultra-low jitter and ultra-low phase noise applications in communication, cable modem, satellite, test & measurement, radar, and other instrumentation. It has a wide application field, high level of frequency accuracy, and is easy to optimize due to its I2C interface. The device also features a wide temperature range and stable, low-noise phase operation.
