Programmable Oscillators are frequency control devices with one or more flop-flops that are sensitive to change either logic levels or frequency from an internal or external source. Among the various programmable oscillators, SIT9005ACE2H-30SI are especially designed for mission critical applications. The type of programmable oscillator minimizes the impact of temperature variations to the frequency stability for a wide temperature operating range.

The SIT9005ACE2H-30SI programmable oscillator provides excellent performance in the form of low jitter and high phase noise, stability over temperature, and voltage. Featuring a frequency range of 500 kHz to 850 MHz, this type of oscillator is suited for applications in wireless, wireless LANs/WiMAXs/satellite communications, military grade systems, RF/IF synthesisers, embedded systems, video surveillance and mission-critical communication systems.

In terms of construction and operation, the SIT9005ACE2H-30SI programmable oscillator is based on a hybrid circuit containing a phase locked loop (PLL) and a multi-output divider. It also includes a control circuit to receive digital instructions and control signals. The input of the control circuit is accessible via an external control interface. When the input control signals and digital instructions are received, these signals are converted into analog signals that are passed to the PLL and multi-output divider. The PLL then controls the oscillator frequency by adjusting its output voltage. The digital instructions are used to configure the oscillator to its desired operation mode, while the control signals are used to adjust the output frequency.

In terms of performance, the SIT9005ACE2H-30SI programmable oscillator has a frequency range of 500 kHz to 850 MHz, with a low jitter of 0.32ps typical and high phase noise of -150dBc/Hz@1Khz offset. The frequency stability of the oscillator is excellent, with stability over temperature of ±0.03ppm/°C for -40°C to +85°C. The supply voltage of the oscillator is also adjustable, allowing for an input voltage range of 2.5V to 3.3V. It also has a low current consumption of 55mA typical.

Overall, the SIT9005ACE2H-30SI programmable oscillator is an excellent choice for a wide range of applications due to its excellent frequency stability and quality. With its ability to operate within 500 kHz to 850 MHz frequency range, low jitter and high phase noise, and low power consumption, it is suitable for mission critical applications such as military grade systems, RF/IF synthesisers, embedded systems and more.
