Programmable Oscillators

Programmable Oscillators (POs) are devices that allow users to program the frequency, phase and other parameters of an oscillator circuit based on their specific needs. Among them, SIT9005ACA1D-30SI is a low power programmable ceramic oscillator module (PO) with a wide range of frequency operation. It is designed to be compact and provide wide frequency coverage from 32.768kHz to 63.8MHz with low power consumption. This makes it suitable for varied applications in areas such as timekeeping, broadcast, communications and computer components.

Application Fields

SIT9005ACA1D-30SI can be used in many fields such as:

• System timing of broadcast equipment and communications equipment.
• System timing of workstations, servers and computers.
• Video, audio and other broadcast equipment.
• Mobile phones and other telecommunications equipment.
• Air defense systems, military communications, radar and other defense equipment.
• Network control devices and networking equipment.

Working Principle

SIT9005ACA1D-30SI works in two basic modes — frequency synthesizer mode (FSM) and frequency divider mode (FDM). In FSM mode, an input clock signal is fed into the oscillator module, which then creates a series of output clock signals with frequencies from 32.768kHz to 63.8MHz. Essentially, it is a voltage-controlled crystal oscillator (VCXO). In FDM mode, an external signal is fed into the oscillator module, which then creates an output signal with a frequency that is a specific divider of the reference signal.

Advantages

SIT9005ACA1D-30SI has several advantages such as:

• Low power consumption, making it suitable for portable devices.
• Small size and light weight, allowing easy mounting and installation.
• Wide frequency range, covering almost all the frequencies used in broadcasting and communications.
• Programmable, allowing users to adjust its settings according to their specific requirements.

Conclusion

SIT9005ACA1D-30SI is a low power programmable ceramic oscillator module with a wide range of frequency operation. It is designed for applications in areas such as timekeeping, broadcast, communications and computer components. It has the advantages of low power consumption, small size and light weight, wide frequency range, and programmability.
