Oscillators are electrical circuits that generate repeating signals in accordance with an input signal. Specifically, the SIT1618AE-23-XXS-48.000000D oscillator is an external voltage-controlled oscillator designed for frequency control and synchronization tasks.

The SIT1618AE-23-XXS-48.000000D oscillator provides a wide frequency range of 0.1 to 48 MHz that makes it suitable for a range of application fields, including frequency/phase locking in high-frequency data links, as well as frequency-sampling and encoding/decoding functions. The high-stability of the SIT1618AE-23-XXS-48.000000D oscillator, combined with its low phase noise and phase-lock performances, make it perfectly suited for high-speed serial synchronization applications. It is also commonly used in mobile and video applications, such as cell phone base stations, satellite ground stations, microwave link systems, and Wi-Fi routers.

The working principle of the SIT1618AE-23-XXS-48.000000D oscillator is based on a voltage-controlled oscillator (VCO) that is tuned by a voltage-controlled frequency divider (VCFD) via an active-loop divider. The voltage-controlled frequency divider consists of two phase frequency detectors and two active-loop dividers connected in a feedback configuration to the VCO to achieve precise frequency control. The active-loop dividers are used to reduce the reference frequency of the VCO, while the phase frequency detectors convert the output frequency of the VCFD to a voltage. This voltage is then fed back to the VCO, providing a precise control of the oscillator frequency. The output frequency of the SIT1618AE-23-XXS-48.000000D oscillator is also determined by its temperature characteristics and the frequency select pin.

The SIT1618AE-23-XXS-48.000000D oscillator is a high-performance, voltage-controlled device that allows for precise frequency control and synchronization tasks. It is primarily used in high-frequency data links, mobile and video applications, as well as other serial synchronization tasks. Its working principle relies on the voltage-controlled oscillator and voltage-controlled frequency divider, where the latter is used to reduce the reference frequency and to control the output frequency of the oscillator.
