Oscillators

Oscillators are essential electronic components used to generate a periodic electrical signal. They have a wide range of uses across many industries such as radio communications, computers, medical equipment, automobile systems, and others. One such oscillator, SIT1602BI-11-XXN-30.000000G, is a type of frequency control oscillator (also known as a phased-locked loop (PLL) chip) which is used to maintain accurate frequency and phase stability for signal transmission.

Application Field

The SIT1602BI-11-XXN-30.000000G oscillator is primarily used in telecommunication applications such as fiber optic transmission systems, satellite ground stations, broadcast radio, Wi-Fi routers, and other commercial and military radio communication systems. It is also used for consumer electronics products such as cordless phones, wireless mouse, and Bluetooth devices. The heavy-duty industrial application of this oscillator includes high-zoom cameras and motion tracking sensors.

Working Principle

The SIT1602BI-11-XXN-30.000000G oscillator operates on the principle of phase-locked loop (PLL) technology which makes use of feedback signals from a voltage-controlled oscillator (VCO) to maintain accuracy and stability of signal frequencies. It uses an integrated crystal oscillator (XO) as the primary source of reference frequency. This reference frequency is fed to the internal phase/frequency detector (PFD) which compares this frequency with the signal generated by the VCO. When the output of the PFD is different from the reference frequency, an error voltage is generated which is then used to adjust the frequency of the VCO. This process is repeated continuously, creating a loop from PFD to VCO, thus ensuring that the VCO operates in sync with the reference frequency.

The output of the VCO is then fed to a loop filter which attenuates the signal, allowing the VCO to adjust its frequency accurately. The output of the loop filter then serves as the primary signal output of the PLL. This signal has very low jitter and very little phase noise which is important for accuracy and stability of the signal.

The SIT1602BI-11-XXN-30.000000G oscillator can be configured to generate various output frequencies in a wide range from 1 kHz to 2 MHz. With its high jitter performance and wide frequency range, it is an ideal choice for radio applications in both commercial and military industries.
