Programmable Oscillators

Programmable oscillators are frequency-controlled oscillators (FCOs) that are programmed to a specific frequency by an external controller, allowing the user to accurately control oscillation frequency without the need to change the hardware. This makes programmable oscillators a valuable tool in applications such as medical equipment, scientific instruments, automotive systems, aerospace, and telecommunications. The SIT9005ACR1G-28EC is an example of a programmable oscillator and can be extremely useful in many of these applications.

SIT9005ACR1G-28EC Application Field

The SIT9005ACR1g-28EC is a triple-output programmable oscillator manufactured by Sitronix Corporation and specializes in low phase-noise, low jitter, and low power consumption. The frequency range for this device ranges from 2.000 to 2.450 GHz, making it an ideal choice for applications like broadband radio test sets, aerospace navigation systems and military radios.

The SIT9005ACR1G-28EC also features a 14-pin HSSOP (Highly-Integrated Standard Small Outline Package) interface with a negative logic, which allows the user to manually adjust the output frequency by changing the logic levels of the CS, CE and UP pins. This output adjustment range is from 63192 kHz to 32662 kHz, which is much wider than the range of conventional frequency dividers. In addition, the SIT9005ACR1G-28EC offers a new level of control and flexibility to the user, as it is able to support adjustable divide ratios, allowing the user to set the frequency with a resolution of 76.9 Hz.

SIT9005ACR1G-28EC Working Principle

The SIT9005ACR1G-28EC is a programmable oscillator with an internal voltage-controlled oscillator (VCO) that is designed to accurately generate the required frequency at any given input voltage level. The output frequency can be set to any desired frequency within the range of the SIT9005ACR1G-28EC by adjusting the input voltage, which is done by the user via the logic level inputs and can be adjusted in increments as small as 76.9 Hz. This allows for great precision in tuning the output frequency.

In addition to being able to adjust the output frequency, the SIT9005ACR1G-28EC also has a power-down mode that allows the output frequency of the oscillator to be disabled when not needed. This is an important feature, as it reduces power consumption, saving power and increasing efficiency.

The SIT9005ACR1G-28EC also includes an integrated temperature-compensated crystal oscillator (TCXO) that provides stable and accurate frequency-drive capability, which is crucial for mission-critical applications. This feature ensures that the output frequency does not vary over time as the ambient temperature changes, enabling the user to rely on the SIT9005ACR1G-28EC for continuous, stable operation.

Conclusion

The SIT9005ACR1G-28EC is an extremely useful programmable oscillator for applications that require accurate control of the oscillator frequency. It offers adjustable divide ratios, low power consumption and temperature-compensated crystal oscillators which ensure accurate and stable performance. As a triple-output device, it can be used to power multiple applications at the same time and is perfect for applications such as broadband radio test sets, military radios and aerospace navigation systems.
