Programmable oscillators are frequently used components in many different industries, including medical devices, automotive systems, and a number of other embedded systems. They are available in a variety of sizes and frequency ranges, making them suitable for a wide range of applications. One such oscillator is the SIT9005ACR1H-33SN, which has become an increasingly popular choice for applications where a programmable frequency range and accuracy are important. This article will explain the application field and working principle of the SIT9005ACR1H-33SN programmable oscillator.

The SIT9005ACR1H-33SN is a single-output, all-digital programmable crystal oscillator with an operating frequency range of 100 kHz to 500 kHz. It can be used in a wide range of applications, including automotive systems, medical devices, industrial control systems, and more. The SIT9005ACR1H-33SN provides a high level of accuracy and stability, which is critical for many applications. Additionally, the oscillator can be programmed via an I2C or SPI interface, allowing for flexibility when selecting the correct frequency range.

The SIT9005ACR1H-33SN utilizes an internally regulated active oscillator that can be programmed via a three-wire SPI or I2C Interface. The oscillator is powered by a 3.3-volt supply, and features a 100 kHz to 500 kHz programmable frequency range, with a standard frequency accuracy of ±2.5 ppm. Additionally, the oscillator features an adjustable frequency accuracy of ±0.5 ppm or ±1 ppm, depending on the type of oscillator. The SIT9005ACR1H-33SN can be programmed using the same software and hardware as the standard SIT7000 models, which means that existing SIT7000 users can experience minimal disruption when upgrading to the new technology.

The SIT9005ACR1H-33SN also features an integrated Programmable Crystal Oscillator (PXO) core. The PXO core ensures that the oscillator operates in an optimal frequency range, while providing accurate frequency accuracy, excellent stability, and fast settling time. Additionally, the oscillator also features Reliability and Supportivity (R&S) certification, which provides assurance that the product is reliable, robust, and suitable for use in critical medical and automotive applications.

The SIT9005ACR1H-33SN can be programmed via a serial port interface. This allows the user to easily customize the frequency range, which can be adjusted in multiples of 100 KHz or 1 KHz. Additionally, the user can also modify the end-stop frequency, output enable enable, temperature sensor enable, and other parameters. The SIT9005ACR1H-33SN can also be configured for an open-loop operation, in which the reference frequency is provided by an external clock signal.

In summary, the SIT9005ACR1H-33SN is an all-digital programmable crystal oscillator, suitable for a wide range of applications. It features excellent accuracy and stability, as well as a programmable frequency range of 100 kHz to 500 kHz. The oscillator can be programmed via an I2C or SPI Interface, and offers flexibility when selecting the correct frequency range. Additionally, the oscillator can be configured for a variety of operating modes, and features Reliability and Supportivity (R&S) certification for critical medical and automotive applications.
