Programmable oscillators come in different forms, serving various purposes. SIT9005ACR2H-30DG is a type of programmable quartz crystal oscillator, providing a wide frequency range of parameters for users to choose from. Generally, its application field is distributed in telecommunications and consumer electronics, such as telecom base stations, handheld devices, and cell phone handsets. Addtionally, projects involving radio frequencies and remote control application can also benefit from its flexibility.The SIT9005ACR2H-30DG is built on a 5x7 mm hermetically sealed package, and comes with an LVCMOS/LVTTL compatible voltage supply and output interface. It features a very low power consumption, excellent frequency stabilization, and a frequency range of 10-140Mhz. It is essential for frequency-sensitive applications, providing a stable frequency guarding against drift even in harsh environments.The SIT9005ACR2H-30DG operates on a simple working principle. It combines the usage of quartz crystals and temperature compensations to generate highly stable frequencies. The component in the oscillator utilizes a quartz resonator to achieve the step of frequency generation, while the following steps rely on a technique called “overtone” to achieve a higher degree of frequency scaling. Specifically, it employs an oscillator chip and three capacitors to accurately tune and adjust the frequency. Additionally, the oscillator utilizes an electrical phase locked loop (PLL) to track, alter rates, and facilitate reasonable phase changes. When there is a change of temperature, a voltage controlled crystal oscillator (VCXO) will be activated by the thermistor to compensate the pulled frequency. The high efficiency of the SIT9005ACR2H-30DG makes it very attractive in various applications, in particular wireless communication systems, music and audio applications, and ISM Band applications. It also plays an important role in global positioning systems, Bluetooth, broadcast satellites and cable TV systems. By combining the functional benefits of high stability and low power consumption, this oscillator is a perfect choice for projects that require reliable frequency and phase maintenance.
