Programmable oscillators are devices with a wide range of applications as they are simple to implement and can provide frequency stability across temperature and aging. Over the years, oscillators have continuously evolved and become more specialized in terms of their output and frequency range while also becoming capable of being modified electronically. The SIT9005ACB1G-XXDP is an example of these recent advances and is part of a series of programmable oscillators used for high frequency applications. In this article, we’ll take a closer look at the SIT9005ACB1G-XXDP and analyze its application field as well as working principle.

Application Field

The SIT9005ACB1G-XXDP by Sitronix Technology Corp is a programmable oscillator with a one gate package. It is suitable for a variety of high frequency applications including clocks for digital computers, mobile phones, and other telecom equipment. Since it is configurable, it can easily be adapted to various frequencies and output waveforms. It has a frequency range of 26MHz to 354MHz, which makes it suitable for a wide variety of applications.

The device utilizes a digitally controlled oscillator (DCO) architecture which provides precise output frequency control and very low frequency accuracy and stability specifications. This makes it suitable for time-critical applications, such as communications and navigation networks. Additionally, the device has low jitter, which reduces interference in communication systems.

The SIT9005ACB1G-XXDP also meets the requirements of many space-constrained systems due to its small size. The device has a one-gate, four-pin package which measures just 0.56 inch x 0.43 inch (14mm x 11mm). This, combined with its low power consumption, makes it ideal for use in portable and battery powered applications, such as smartphones and other mobile devices.

Working Principle

The SIT9005ACB1G-XXDP utilizes a digitally-controlled oscillator (DCO) architecture. This utilizes feedback to ensure precise output frequency control and stability. The device works by taking an input reference frequency and then using a digital loop to track and maintain the output frequency. This is done by continuously monitoring the output frequency and then adjusting the control voltage as needed to ensure the output frequency remains at the desired frequency.

The SIT9005ACB1G-XXDP can also be programmed over a wide frequency range in 1 to 3 ms increments. Up to four different operating frequencies can be programmed into the device and can be changed by simply toggling the CTL- and CTL+ pins. Additionally, the device has integrated pullability tuning which can be adjusted via the CTL+/CTL- pins. This allows the user to adjust the pull range as well as the range step, thus allowing for greater frequency accuracy.

The SIT9005ACB1G-XXDP has several other features which make it suitable for use in high frequency applications. It has a low-frequency jitter of 0.275ps and a high-frequency jitter of 0.400ps. The device also has an integrated output enable/disable function, which allows the user to quickly switch between different frequencies without having to power down the device. Additionally, the device is RoHS compliant, making it ideal for use in green products.

In conclusion, the SIT9005ACB1G-XXDP is an ideal choice for a wide range of high frequency applications. Its DCO architecture allows for precise frequency control and very low jitter. It also has a wide programming range, enabling it to be adapted to different frequencies, pull range and step sizes. Additionally, its small size and low power consumption make it suited for space-constrained and battery-powered applications. All these factors make the SIT9005ACB1G-XXDP a versatile device for use in today’s applications.
