633E20006C2T Datasheet/PDFOscillators are systems that maintain a constantly repeating periodic motion. The 633E20006C2T oscillator is a Frequency-Time Product (FTP) oscillator that delivers precise timing and frequency control needed for applications operating in a high frequency environment. The oscillator performs two key functions: providing an output clock at a desired frequency, and controlling the cycle timing of the clock input.
Application Field
The 633E20006C2T oscillator has an operational frequency up to 200 MHz, and is capable of providing accurate timing and frequency control for communication, aerospace, industrial, and many other high frequency applications. Some application areas for this oscillator include: servers and routers, aircraft cockpits, avionic systems, digital imaging, and communication and signal processing systems.
Working Principle
The 633E20006C2T oscillator works by taking in a clock input and providing a clock output of the desired frequency. The oscillator uses an internal control loop to adjust the clock output frequency, which is compared to a reference clock. The loop is responsible for adjusting the frequency of the clock output to remain as close to the reference clock as possible. In order to ensure the frequency accuracy, the 633E20006C2T oscillator utilizes temperature compensation technology to help keep the clock output frequency accurate even in the presence of temperature fluctuations.
The internal control loop of the 633E20006C2T oscillator is based on a Phase Locked Loop (PLL) architecture. The main components of PLL\'s architecture are a phase comparator, the VCO (Voltage Controlled Oscillator), a divider, a filter, and a programmable counter. The phase comparator is responsible for comparing the phase between the reference clock and the feedback clock output, and generating a control voltage. This control voltage is then used to control the output of the VCO, and to keep the frequency of the clock output as close as possible to the reference clock. Finally, the programmable counter changes the frequency of the clock output to adjust for drift or other variations in the signal frequency.
The 633E20006C2T oscillator provides highly accurate, dynamic, and reliable frequency control even in a wide temperature range of -40°C to +105°C. The oscillator offers high-frequency stability, high-temperature stability, and low jitter. This makes it an ideal choice for applications that require precise frequency control and low jitter performance.
