Programmable oscillators are electronic circuits that, when provided with a particular set of inputs, can generate precisely tailored output signals. The SIT9005ACA2H-28DE is a recent addition to the range of programmable oscillators available on the market. This device combines the convenience of a programmable oscillator with the versatility of an Application Specific Integrated Circuit (ASIC).

The SIT9005ACA2H-28DE is designed to provide a wide variety of possible oscillation frequencies across different input clock frequencies, spanning a range of 5 to 28 MHz. It is intended for use in applications such as frequency-hopping systems, GPS synchronization, infrared remote control and radio telemetry systems, among others. In addition, the device\'s programming flexibility offers the potential for lower power consumption, reduced package size and improved overall system performance.

The working principle of the SIT9005ACA2H-28DE is based on Direct Digital Synthesis (DDS). This type of oscillator uses a digital counter to generate a wave frequency within a range programmed by a digital ‘word’. The counter cycles through the values of the word, which represent discrete voltage levels, to produce a waveform. The DDS architecture allows for a wide range of possible frequencies to be generated, which is useful in applications such as frequency-hopping systems. It also enables the generation of signals corresponding to a specific frequency within that range; an important feature in applications that require precision.

The SIT9005ACA2H-28DE incorporates a PLL (Phase Locked Loop) that allows its frequency resolution to be tweaked in order to achieve higher accuracy. This is an advantageous feature that enables the device to be used in more applications, such as vibration monitoring and communications modulation. Other useful features of the SIT9005ACA2H-28DE include its resistance to environmental conditions and its immunity to electromagetic interference. This ensures that it can be used safely in a variety of situations.

In summary, the SIT9005ACA2H-28DE is a high-precision programmable oscillator. It is ideal for applications such as frequency-hopping systems, GPS synchronization, infrared remote control and radio telemetry systems. Its features, such as its phase locked loop, allow it to be used in more demanding applications that require high accuracy, and its resistance to environmental conditions and immunity to electromagnetic interference further enhance its versatility. As such, the SIT9005ACA2H-28DE can make a valuable contribution to a wide range of applications.
