Programmable Oscillators

Programmable oscillators are devices that generate electrical signals with specific frequencies, typically through the application of a voltage or current. They are used in a variety of applications, from embedded systems to medical devices to industrial and consumer electronics. The SIT9005ACR1D-28NM is a programmable oscillator designed to provide reliable and accurate signal frequencies and timing in a wide range of applications.The SIT9005ACR1D-28NM is a surface mount, programmable oscillator that produces a frequency of 26 to 28MHz with a typical accuracy of 1.4 parts per million (ppm). It supports a wide range of operating temperature, from -40°C to 85°C, and is replaceable with SITDEPS9005ACR-28NM and SITDEAM0011ACR-31NC models.The SIT9005ACR1D-28NM is based on a technology called Phase-Locked Loop (PLL) which is used in many types of electronic circuits for a variety of purposes, including synchronization, frequency modulation, and frequency Multiplexing. In order to achieve an accurate frequency output, the oscillator requires a stable source of power, with very little variation over time, temperature and current.When applied to the SIT9005ACR1D-28NM, the PLL works by using a voltage-controlled oscillator (VCO) to generate an input signal with a reference frequency. The reference frequency is divided down by the divider, which is controlled by the output of a digital-to-analog converter (DAC) that is addressed by a digital word. The value of the DAC determines the frequency of the output signal, thus it can be programmed to generate any desired frequency in the range specified by the oscillator.The output frequency can be adjusted to as close as one Hz, and the accuracy of the oscillator is due to the low temperature coefficient of the SITTL9005ACR-28NM, which ensures that the oscillator maintains its accuracy over a wide temperature range. The output is integrated with a crystal oscillator, which provides an additional level of stability for the output signal.The SIT9005ACR1D-28NM is widely used in embedded systems, especially for timing control or synchronization, such as in wireless communication, as well as in medical and industrial applications. The oscillator can also be used in consumer devices, as part of audio synchronization and timing control systems.The SIT9005ACR1D-28NM is a reliable and highly accurate programmable oscillator with a range of applications, and its wide temperature range makes it ideal for a variety of embedded systems and industrial applications. It is a great choice for applications that require reliable and highly precise signal frequencies and timing.
