Programmable Oscillators represent a versatile, cost-effective solution to a range of applications that require an accurate and stable signal. These signal sources, often referred to simply as oscillators, have been a staple of operation and control electronics for decades. One particular oscillator, the SIT9005ACR2D-28NG, offers superior performance and a range of features which make it suitable for use in many applications. This article will provide an in-depth overview of the features, application field, and working principle of the SIT9005ACR2D-28NG.

Features of SIT9005ACR2D-28NG

The SIT9005ACR2D-28NG is a direct digital synthesis based programmable oscillator which features a frequency range of 8kHz to 8GHz. The output frequency is programmable in 1Hz steps and is also adjustable over a range of ±0.5%, ±1.0%, and ±2.0%, making it suitable for applications which require a highly accurate signal. The SIT9005ACR2D-28NG offers a low phase noise of -150dBc/Hz and harmonical suppression of up to -60dbC, making it ideal for use in applications which require a clean and un-distorted signal such as communications and radio frequency (RF) applications. The device is also available in a choice of packages, including SMD (Surface Mount Device), LCC (Leadless Chip Carrier), and CSP (Chip Scale Package), as well as numerous operating temperatures (from -40°C to 125°C) for compatibility with a wide range of applications.

Application Field of SIT9005ACR2D-28NG

The SIT9005ACR2D-28NG is suitable for a range of industrial and consumer applications. Its small size and wide operating temperature make it ideal for use in mobile and handheld devices, where the reliable signal is necessary to maintain communications. The SIT9005ACR2D-28NG’s highly accurate signal also renders it suitable for use in critical applications such as medical diagnostics, where an accurate and stable signal is essential. In addition, its low phase noise, low current consumption and wide frequency range make it ideal for use in communications applications such as satellite navigation, satellite communications, and radio astronomy.

Working Principle of SIT9005ACR2D-28NG

The SIT9005ACR2D-28NG uses a Direct Digital Synthesis (DDS) technology, in which a frequency-synthesized sine wave is generated using digital parameters to define the output signal. The device operates by taking a digital word from a higher-frequency reference signal, known as a derivative clock, and converting it into a pulse-width-modulated (PWM) control voltage. This PWM control voltage is then applied to an analog loop filter and a low-distortion VCO (Voltage Controlled Oscillator), which acts to synthesize a signal with the required frequency. The output from the VCO is then passed through a low-pass filter, in order to remove any higher frequency noise and produce a clean signal.The frequencies outputted by the SIT9005ACR2D-28NG are both programmable and adjustable, meaning it can be used in multiple applications which require a stable and reproducible signal. The device also contains integrated digital control circuitry which simplifies the programming of different frequencies, enabling tuning of the output frequency to the exact specifications necessary for each application.

Conclusion

The SIT9005ACR2D-28NG programmable oscillator is a versatile and reliable signal source which can be used in a wide range of applications. Its range of features, including an adjustable output frequency, low phase noise, harmonical suppression, and small size, make it suitable for use in communications, medical diagnostics, and handheld and mobile applications. The device uses Direct Digital Synthesis (DDS) technology to generate a sine wave of adjustable frequency, and also contains integrated digital control circuitry to simplify programming. As such, the SIT9005ACR2D-28NG is an ideal choice for many applications which require a stable and reproducible signal source.
