SIT9003AC-3-18DD

Programmable Oscillators have become an increasingly essential tool across many disparate industries. The SIT9003AC-3-18DD is a prime example of the type of oscillator that can be used in a variety of applications, and it is a great choice to include in any engineer’s toolkit. In this article, we will discuss the application field and working principle of the SIT9003AC-3-18DD programmable oscillator.

The SIT9003AC-3-18DD oscillator is designed to generate an output frequency of 3.18 MHz while consuming very little power. It utilizes a crystal frequency of 3.18 MHz and a resonator, which is then amplified by an internal amplifier to create an output signal. The output frequency can be adjusted via a series of command and enable pins, allowing for external programming of the frequency. In addition, the SIT9003AC-3-18DD utilizes a variety of features such as a COS/MOSFET switch for compatibility with various clock-derived signals, and a power-down mode that allows for low power consumption when the oscillator is not in use.

The wide range of application fields that the SIT9003AC-3-18DD is capable of fitting in are numerous. It is most often used in the multimedia and audio communications markets, either as a clock source or as a frequency generator, as it allows for accurate timing of operations. Due to its low power consumption properties, it is ideal for use in applications such as mobile phones, PDAs, and portable navigation devices. Additionally, it can also be used in automotive systems, such as car stereo and onboard navigation systems, as well as in industrial settings such as in precision timing clocks and robotics.

The working principle of the SIT9003AC-3-18DD oscillator is based on a resonator and amplifier circuit. Initially, the oscillator receives a seed signal from a crystal frequency of 3.18 MHz. The resonator takes the signal and amplifies it to an acceptable level as it is fed through an amplifier stage. After passing through the amplifier stage, the signal is sent to a comparator and converted to a digital output. The digital output is then sent to the programming pins, which can be used to adjust the output frequency of the oscillator.

The SIT9003AC-3-18DD is an excellent example of a modern programmable oscillator. It boasts a plethora of features and is capable of providing an accurate output frequency in a variety of settings. As a practical tool, this device is capable of meeting the needs of any engineer in the field of multimedia, audio or automotive systems. Furthermore, as a result of its low power consumption, the SIT9003AC-3-18DD is a great choice for embedded applications as well.
