The SIT9002AI-03H25DO is a Programmable Oscillator (POS) designed for the embedded applications. The POS device is constructed with a 25 MHz crystal blank and has a frequency span of 0.1 - 4 MHz. It is designed to provide a highly reliable and low power consumption accuracy and can be used in a wide variety of applications including frequency control, system synchronization and timing control.POS devices are characterized by their ability to vary their frequency in accordance with an external command. The SIT9002AI-03H25DO device is able to switch from one frequency to another and provides a stable and accurate frequency control. This is made possible through the use of a precision microcontroller-based design.The oscillation inside the SIT9002AI-03H25DO is generated by a small crystal blank, which is loaded with a pre-calibrated calibration resistor. This allows the oscillator to operate within a predetermined frequency range. The crystal is connected to the microcontroller and an oscillation frequency is generated when a signal is given through an external command. The external command is sent from a CPU or other device and is read by the oscillator.The SIT9002AI-03H25DO has two main ways in which it can operate:1. Parallel mode: The oscillator operates in parallel in this mode, where the frequency output is controlled by an external command and an internal counter. The internal counter is used to track the number of clock cycles for each cycle of the oscillator. This prevents the frequency from changing too quickly and helps to maintain a consistent frequency.2. Serial Mode: The oscillator works in serial mode where the frequency is changed by a series of external commands sent to the microcontroller. The frequency changes are controlled by the microcontroller and are transmitted to the crystal through a serial link. The serial link uses UART (Universal Asynchronous Receiver-Transmitter) to communicate with the device.No matter which mode is used, the SIT9002AI-03H25DO is designed to deliver an accurate frequency with a low power consumption. It is able to provide a frequency ranging from 0.1 to 4 MHz and can maintain a consistent frequency under a wide range of temperatures. The artificial intelligence (AI) functionality enables the POS to maintain its clock accuracy even when there are large changes in the surrounding conditions.The SIT9002AI-03H25DO device is ideal for applications where precision timing and low power consumption are important. Some of the applications for this device are radios, navigation systems, and other embedded applications. It can also be used for frequency control, system synchronization, and timing control in a variety of applications.Overall, the SIT9002AI-03H25DO is an excellent choice for a wide variety of applications that require precision timing with low power consumption. With its highly reliable, AI-based clock accuracy, the SIT9002AI-03H25DO is sure to provide an effective solution to many timing problems.
