Programmable oscillators are energy efficient, feature adjustable stability and frequency, and come in sizes that range from small SMD (SMT) to larger leaded packages. The SIT8008ACR3-33E is a particular type of programmable oscillator. It offers a wide frequency range with an adjustable output from 18 to 55 MHz and a precise stability of ∼20ppm over a range of 0° to +70°C. This device is well suited for consumer electronics, communications, office automation applications, as well as various industrial applications.

The SIT8008ACR3-33E is a crystal based PLL oscillator and uses a crystal to generate a specific frequency. This frequency is then fed into a phase-locked loop (PLL) placed inside the oscillator. The PLL multiplies the input signal, resulting in a higher frequency output. The device also features an integrated voltage controlled oscillator (VCO) which acts as a frequency multiplier and divides the output signal, resulting in a precise and accurate output frequency. Additionally, the SIT8008ACR3-33E has a wide frequency range and a precise stability of ∼20ppm ±5%.

The SIT8008ACR3-33E uses a varactor diode-based tuning voltage control input (VCTCXO) with a tuning voltage range from 5V to 10V. This allows for fine-tuning of the frequency output in order to ensure stable and accurate operation. The device has an enable/disable that allows the oscillator to be quickly deactivated in order to save power or switch to a different output frequency without having to power cycle the oscillator. Furthermore, the device has an integrated thermal regulation circuit that helps to maintain a constant temperature and minimizes drift during operation.

The SIT8008ACR3-33E has a wide operating temperature range of -20° to +70°C and can operate at the full voltage range from 3V to 5.5V. The device is provided in an SMT 16-pin LCC package with an impedance of 50 Ohms. It is ideal for applications that require small board space, low power consumption, high reliability, and accurate and stable frequency output. This device is appropriate for consumer electronics, office automation, communications and various industrial applications.

In conclusion, the SIT8008ACR3-33E is a crystal based PLL oscillator that offers precision frequency output over a wide range of operating temperatures. Its small size, wide operating temperature range, and adjustable frequency output make it an ideal choice for applications in consumer electronics, communications, office automation and various industrial applications.
