Programmable oscillators, or varicap-tuned oscillators, are electronic oscillators whose frequency can be easily programmed or adjusted without the need to modify other components in the circuit. The SIT9005ACR1D-28DG is one such oscillator. This oscillator is capable of accurately producing a wide range of frequencies from 3 kHz to 255 MHz with a dedicated 4-bit binary code.

The SIT9005ACR1D-28DG features a wide temperature range of -40 to +85°C, which makes it suitable for use in environments where temperature variations can range significantly. The oscillator also features very low phase jitter (~1 ps) and is inherently stable over a wide temperature range. This makes it ideal for applications requiring stable and reliable high performance clock signals over a wide range of temperatures.

The SIT9005ACR1D-28DG has an application field in various industries including telecoms, mobile phones and GPS systems, of which this oscillator is capable of providing reliable clock signals for. The programmable oscillator also finds use in test and instrumentation equipment, automotive electronics, aerospace applications, broadcasting equipment and video systems.

The SIT9005ACR1D-28DG oscillator has a simple working principle by using a varicap-tuned oscillator. It consists of an oscillator core section and a reference input voltage control section. The core section\'s circuit (as pointed out in its datasheet) consists of an amplifier, oscillator, output buffer and a set of series-connected 0.5pF varicaps. The reference voltage control section can adjust the ring voltage to one of 16 different reference voltage levels, which is used to adjust the capacitance of the varicaps. This changes the frequency of the oscillator in precise steps.

The digital control signals for an SIT9005ACR1D-28DG are supplied in a 4-bit binary code. This is used to set the reference voltage control section of the oscillator to a particular level, and thus set the precise frequency of the oscillator accordingly. The 4-bit binary code is transmitted to the oscillator when power is supplied to the oscillator.

The SIT9005ACR1D-28DG oscillator is an efficient and reliable programmable option for applications requiring precise high performance clock signals over a wide range of temperatures. It features very low phase jitter and high stability, making it suitable for high-speed data transmission systems in various industries including telecoms, mobile phones and automotive electronics.
