Programmable Oscillators are able to keep high accuracy timing in various time ranges, regardless of the environment, and have wide applications across various fields including automotive, computer, health care and communication. SIT9003AC-3-28DO is a specially designed programmable crystal oscillator (PXO) and has been widely used in the production of high frequency, low power and stable AC circuits.

The SIT9003AC-3-28DO is a programmable oscillator module embedded with a tri-state digital output interface and an I/O port. It is designed with a wide operating frequency range from 1kHz to 20mHz and a wide supply voltage range from 3.3V to 28V. This oscillator module is available in three different packages, including SOT-23, PDIP, and SOIC.

The working principle of SIT9003AC-3-28DO is based on the principle of crystal oscillation. The crystal is mounted on the module and a voltage is applied to excite the crystal. The crystal oscillator module is then used to create a timing circuit to achieve a certain frequency. The module consists of an oscillator, a frequency divider and an amplifier. The oscillator changes the input frequency to an output frequency by passing current through the crystal. The frequency divider then divides the output frequency to a much lower frequency that can be used in the AC circuit. The amplifier then amplifies the voltage level so it can be used in the AC circuit without over-heating the components. The I/O port\'s bidirectional interface allows the user to program the desired frequency and duty cycle through an external chipset.

The SIT9003AC-3-28DO programmable oscillator has multiple applications due to its high frequency and stability. It is widely used in consumer electronic products such as home entertainment systems, laptop computers, and cell phones. It is also used in automotive electronics such as engine control systems, radio navigation systems, and ignition control systems. Furthermore, SIT9003AC-3-28DO is frequently used in medical field for devices such as ECG monitors, pacemakers, and biochemical sensors.

In conclusion, the SIT9003AC-3-28DO is a programmable oscillator module which is highly accurate, efficient, and stable. Its wide operating frequency range and low power consumption makes it suitable for various applications, ranging from consumer electronics, to automotive electronics and medical devices.
