SIT9005ACR1H-25SG

Programmable Oscillators are electronic circuits with variable frequencies that are designed to quickly switch between different frequencies often on the order of one second or less. They are frequently used in applications where multiple frequencies are required such as in radio frequency (RF) communications, digital electronics, and in radar systems. SIT9005ACR1H-25SG is a type of programmable oscillator. It is well suited for applications that demand internal adjustment of frequency without external tuning and the need for post assembly tuning.

The SIT9005ACR1H-25SG Programmable Oscillator has a frequency range of 5 MHz to 25 MHz and is part of the series of Voltage Controlled Crystal Oscillators (VCXOs) from SITMI. It has a 10 mV/Volt tuning sensitivity and operates from a 3.3 Volt supply with an operating current of 15mA. The SIT9005ACR1H-25SG also features TTL output on its Pierce inverting buffer. This allows it to be used in many applications such as communication systems, automotive testing, frequency synthesizers and industrial equipment.

SIT9005ACR1H-25SG is based on the concept of controlling the oscillation frequency by applying a control voltage. The output frequency is produced by the Pierce inverting buffer which is driven by a current branch in the oscillator circuit. With the help of the Pierce inverting buffer, the SIT9005ACR1H-25SG supplies square waves with less than 12ns rise and fall times. Therefore, it has a high degree of accuracy and stability.

The SIT9005ACR1H-25SG Programmable Oscillator is designed to be used with a digital control circuit or an analog voltage control source. In the former case, the digital signal supplied is typically a binary coded four bit word which is fed to the oscillator directly. In the latter case, an analog voltage is used to control the output frequency by changing the current in the Pierce inverting buffer. The control range of the analog voltage is generally 0V to 5V.

The main application fields of the SIT9005ACR1H-25SG Programmable Oscillator include radio frequency (RF) communications, digital electronics, radar systems, as well as automotive testing, frequency synthesizers and industrial equipment. In RF communications, it can be used to generate multiple frequencies to transmit and receive signals. In digital electronics, the oscillator can be used to provide signals needed for clocking data. The oscillator can also be used in radar systems to produce a swept tuning signal for signal processing.

In conclusion, the SIT9005ACR1H-25SG Programmable Oscillator is an ideal component for applications that require both frequency flexibility and high degree of accuracy and stability. It is suitable for multiple types of applications such as RF communications, digital electronics, and radar systems. The oscillator can be used with a digital control circuit or an analog voltage control source depending on the specific application requirements.
