Programmable oscillators are electronic devices whose operating frequencies are generated according to programmed settings. The SIT9005ACU1G-28DF is a programmable oscillator manufactured by Sitronix. It is a dual frequency oscillator, with two separate output signals at different frequencies. Specifically, it can output frequencies of 1GHz and 28MHz, respectively. It is also possible to program the frequencies to allow for frequency hopping.

The SIT9005ACU1G-28DF is primarily used in devices that require the ability to communicate with multiple frequencies. This could include devices such as dual-frequency radios, global positioning systems (GPS), and devices that require precise frequency synchronization such as radar systems. Sitronix provides a range of applications for this programmable oscillator, including mobile communication, instrumentation, test and measurement equipment, and broadcast transceivers.

The SIT9005ACU1G-28DF operates according to the voltage-controlled oscillator (VCO) principle. A voltage is applied to the oscillator circuit to control the frequency of the output signal. The SIT9005ACU1G-28DF incorporates a dual-frequency VCO with two separate outputs. The output frequencies can be adjusted by varying the voltage applied to the VCO. The oscillator circuit also includes a phase-locked loop (PLL) which allows the frequencies to be synchronized, allowing for frequency hopping.

The SIT9005ACU1G-28DF is a compact and cost-effective solution for applications requiring precise frequency control and synchronization. It is integrated in a small BGA package, making it suitable for PCB integration. It is also designed to be RoHS compliant and is capable of operating in temperatures ranging from -40 °C to 85 °C. This makes it suitable for a range of industrial, automotive and consumer applications.

In summary, the SIT9005ACU1G-28DF is a programmable oscillator from Sitronix. It is capable of outputting two separate frequencies of 1GHz and 28MHz, and allows for frequency hopping. It is primarily used for applications requiring dual frequency communication, such as radios and GPS systems. It operates on the voltage-controlled oscillator principle, and includes a PLL for precise frequency synchronization. The oscillator is integrated in a small BGA package, RoHS compliant and can operate in a wide temperature range, making it suitable for a range of applications.
