SIT9003AC-2-33SQ

Programmable Oscillators are a type of electronic timing device that use a set of programmable internal components in order to produce a specific frequency at a certain voltage. The SIT9003AC-2-33SQ is one such device, which has a wide range of applications and a versatile working principle.

Applications

The SIT9003AC-2-33SQ is a highly versatile programmable oscillator with a wide range of applications. It is commonly used in mobile phones, digital TVs, game consoles, set-top boxes, navigation systems, and medical equipment due to its adjustable frequency range and excellent performance. In addition, this oscillator is also suitable for many other applications, including radio frequency identification (RFID) systems, wireless networks, radio detection and ranging (radar) systems, sonar systems, global positioning systems (GPS), and others.

The SIT9003AC-2-33SQ is also an ideal choice for 6-80MHz noise-free broadband frequency applications. This oscillator\'s power supply can exceed 10kHz ensuring that the receiver can accurately receive signals and maintain synchronization. Meanwhile, the oscillator’s low harmonic content ensures that the receiver remains undisturbed from frequency interference, a key point when dealing with sensitive applications.

Working Principle

The SIT9003AC-2-33SQ is powered by a programmable crystal oscillator and support voltage. The crystal oscillator is a quartz crystal device with a wide frequency range that can be programmed to the desired frequency through the oscillator’s pin voltage adjustments. The power supply is provided through the oscillator’s control voltage, allowing the user to select the optimum power supply voltage to meet the required frequency range.

The crystal oscillator will then convert the input frequency into a square wave output. This square wave output is then processed by the oscillator\'s two frequency dividers, producing a 3-bit digital frequency code. This digital code is then sent to a phase comparator, which produces an output signal that is used to control the voltage applied to the crystal oscillator. The oscillator remains in a stable state until the next frequency input is received when the process is repeated.

Once the oscillator reaches its desired frequency, it will enter a low power consumption mode. This mode ensures that the oscillator maintains its frequency without wasting energy or overheating. This is a critical feature when dealing with battery-powered devices or energy-intensive applications.

The SIT9003AC-2-33SQ is a highly versatile programmable oscillator with a wide range of applications. Its adjustable frequency range and excellent performance make it an ideal choice for many applications. In addition, its low power consumption mode ensures that power is conserved, making it an efficient choice for energy-intensive applications.
