Programmable oscillators are electronic components that generate a periodic electronic signal without the need for an external device or source to be driving it. This type of oscillator has the ability to be controlled and configured to generate any desired frequency from square wave, triangle wave, and sine wave. They are widely used in embedded systems for time base generation, bit clock generation, and for time-division multiplexing (TDM).

The SIT9005ACU2D-18DH is an all-digital CMOS programmable oscillator. It features low jitter performance and low power consumption by combining certain features of silicon and quartz technologies.

The main application field of the SIT9005ACU2D-18DH is in the generation of high- stability clock signals. It is particularly suitable for use in embedded systems, communications and broadcast systems, industrial control systems, and medical equipment. It has a wide range of applications in the test and measurement and automotive markets.

The SIT9005ACU2D-18DH is powered by an internal voltage regulator and requires no external power. It can generate a variety of square, triangle and sine waves from a single source. The frequency range of the output signals can be customized, and multiple oscillators can be cascaded for higher frequency applications.

The SIT9005ACU2D-18DH has an internal digital signal processing (DSP) unit which is used to control and configure the frequency, phase and amplitude of the signal. It also has an integrated voltage controlled oscillator (VCO) which is used to produce the output signal. The VCO can be programmed to produce different frequencies, and the DSP can be used to control the phase and amplitude of the signal. The SIT9005ACU2D-18DH also has an internal memory which can store the settings for the frequency, phase and amplitude.

The SIT9005ACU2D-18DH can be operated in either runaway or closed loop mode. In runaway mode, the internal DSP continuously monitors the output signal and adjusts the frequency, phase and amplitude accordingly to maintain the desired frequency and phase accuracy. In closed loop mode, the DSP adjusts the settings of the VCO to maintain the desired frequency.

The SIT9005ACU2D-18DH has an integrated temperature sensor which is used to compensate for temperature effects on the output signal. This ensures that the signal remains stable even when the ambient temperature changes. The temperature compensation can be programmed to achieve the most efficient and accurate performance.

In conclusion, the SIT9005ACU2D-18DH is an all-digital CMOS programmable oscillator. It offers excellent performance and low power consumption by combining certain features of silicon and quartz technologies. It is suitable for use in embedded systems, communications and broadcast systems, industrial control systems, and medical equipment. It has a wide range of applications in the test and measurement and automotive markets.
