Programmable oscillators, such as the SIT9005ACT2G-25DP, are electronic components capable of producing repeating electronic waveforms such as clocks, frequency dividers, and waveform generators, as well as allowing an external user to program the frequency of the waveform. While traditionally, timing and waveform control were done at fixed internal frequency, the benefit of programmable oscillators is that they can generate waveforms over a wider range of frequencies, allowing engineers to customize and optimize their designs.

The SIT9005ACT2G-25DP is a high-performance dual phase-locked loop (PLL) clock, offering low jitter and phase noise performance in a small form factor. Particularly, it is designed to minimize electromagnetic interference (EMI). This makes it ideal for high-end consumer electronics and computing applications that have stringent EMI requirements, such as wireless and cellular phones, digital cameras, and medical imaging systems. It is also especially suitable for applications that require exact clock distribution, such as digital signal processors (DSPs) and ASICs.

The SIT9005ACT2G-25DP is a monolithic oscillator, which means that the component is a single integrated circuit of multiple transistors, resistors, or capacitors. This allows the device to be controlled by a single DC voltage supply. The device is equipped with two programmable references: a master reference clock input and a second reference clock input. An internal frequency multiplier circuit allows the user to program the frequency of the waveforms, while a set of external control inputs allow further flexibility.

The SIT9005ACT2G-25DP contains a wide selection of output frequencies, starting from 1MHz up to 25MHz. The device has two reference oscillators, a wide frequency range, and a wide range of output waveforms. The SIT9005ACT2G-25DP\'s basic function is to act as a frequency reference on a board, and it does this by generating a series of pulses at a predetermined frequency rate. These pulses determine the timing and frequency of the waveform generated by the component.

The SIT9005ACT2G-25DP uses a voltage-controlled oscillator (VCO) to create a waveform which is then fed into a phase-locked loop (PLL). The PLL takes the waveform from the VCO and analyzes it. The PLL compares the input waveform with a reference clock waveform generated internally, and continuously adjusts the output frequency of the waveform until it is perfectly in sync with the reference waveform. Once it finds the correct frequency, the waveform\'s phase and frequency remain locked to the internal reference waveform, meaning that the output waveform is generated with very low jitter and phase noise.

The SIT9005ACT2G-25DP is capable of producing both square and sinusoidal waveforms of up to 1.6GHz. Additionally, it also supports phase-shifted waveforms, allowing it to be used as a frequency divider, phase shifter, or noise generator. Furthermore, the device can be configured as a master-slave type PLL, where both outputs are synchronized with the input waveform. This is especially useful for applications such as fault-tolerant systems and communications where reliable timing signals are of the utmost importance.

The SIT9005ACT2G-25DP is versatile due to its wide range of output frequencies and can be used in many different applications. These applications range from high-end computing, networking and communication systems to embedded applications in industrial, automotive, and medical systems. As such, the SIT9005ACT2G-25DP is the ideal choice for today\'s demanding applications requiring precise control of frequency, timing, and phase.
