Programmable oscillators are the devices with frequency setting ability, which could be programmed through an external device and works to generate a specific frequency for an indefinite time.

SIT9005ACA2D-33DP is a type of programmable oscillator, manufactured by Sitronix Technology Corporation to provide customers with a reliable solution and a range of sizes, frequencies, and applications available. It is offered in SMD packages, such as 2.0 x 1.6mm, 2.5 x 2.0mm, and 3.2 x 2.5mm, respectively, and works on a frequency range of 1.00 MHz to 66.0 MHz. The product ensures stability and reliability with the help of a built-in crystal oscillator and low noise features, which make it ideal for a variety of applications.

The applications for SIT9005ACA2D-33DP include USB communication, DVD/VCD playback, point-of-sale terminal, handheld device, video game economy, and peripheral. In USB communication, the oscillator helps establish a connection to the PC, with output frequency in the operating range of between 8 and 11MHz to accomplish this. The SIT9005ACA2D-33DP can also be used in DVD/VCD playback, as it is able to maintain crystal-clear audio output levels for long duration. It also offers a low power consumption feature, which makes it suitable for point-of-sale terminals and handheld devices. Furthermore, the oscillator can be used in video game economy, such as Playstation and Xbox, to maintain a smooth framerate as per specific gaming needs. As for peripherals, the SIT9005ACA2D-33DP is able to provide controllers and sensors with stable high-speed signals.

As for the working principle, the oscillator is based on a frequency setting circuit, which is a highly integrated design, with multiple small size components combined together to achieve the frequency setting function. It includes an integrated quartz crystal oscillator, an external frequency-setting pin, and a frequency setting ADC/DAC (Analog to Digital Converter/Digital to AnalogConverter) circuit. Together, these components enable the oscillator to generate accurate and repeatable frequencies within the specified range with minimal error.

The frequency setting ADC/DAC circuit helps to determine the frequency of the output. It is responsible for digital to analog conversion by transferring the input digital signal into an analog output value. It also responsible for analog to digital conversion, which converts an analog input into a digital output. This is achieved with the help of several integrated voltage references, which enable the oscillator to accurately and precisely adjust its output frequency. On the other hand, the quartz crystal oscillator provides the stability and reliability of its frequency by maintaining the desired accuracy of the frequency-setting pin.

To sum up, SIT9005ACA2D-33DP is a type of programmable oscillator, manufactured by Sitronix Technology Corporation to offer customers reliable solutions. Its applications include USB communication, DVD/VCD playback, point-of-sale terminal, handheld device, video game economy, and peripherals, while its working principle is based on a frequency setting circuit, with the help of an integrated quartz crystal oscillator, an external frequency-setting pin, and a frequency setting ADC/DAC circuit.
