Programmable Oscillators are a type of timing device in which frequency and waveform parameters can be dynamically altered. They are well-suited for use in applications with high accuracy, low noise and low phase jitter requirements. There are a number of types of oscillators available, including phase locked loops (PLLs), phase modulation (PM) oscillators, direct digital synthesis (DDS) oscillators, and software-defined oscillators. SIT9005ACE1D-28DK is a type of DDS oscillators, a reliable, low-power, and inexpensive precision oscillator suitable for SONET/ SDH, optical networks, telecom, telecom-grade test and measurement, high-performance timer/counter cards, and high-resolution signal generators.
SIT9005ACE1D-28DK DDS oscillator is a modern, full featured, digital-controlled oscillator designed for vital timing applications in the telecom and data communications markets, as well as other life-critical areas. It provides a simple, cost-effective way to accurately program frequency and waveform parameters to achieve the most accurate desired results. The device includes a high-resolution, internal Digital-to-Analog (D/A) converter, along with a PLL, allowing the SIT9005ACE1D-28DK to generate outputs ranging from 28MHz to 6GHz. Additionally, the oscillator comes with low jitter performance of less than one picosecond and outstanding switching speed (<40 nanoseconds), making it ideal for a wide range of frequency applications.
One of the key features of SIT9005ACE1D-28DK is its ability to select the desired frequency output from a set of programmed frequencies over a wide range. This is accomplished through the use of a microprocessor and digital source that contain all of the necessary parameters for the oscillator to operate. The microprocessor is used to read the programming information, convert the information into a digital signal, and then send the signal to the oscillator. The oscillator then uses this digital signal to set the output frequency. This digital control allows for precise synchronization of the timing signals which is beneficial in telecom applications.
Another beneficial feature of the SIT9005ACE1D-28DK is its adjustable-frequency output, which can be programmed to adjust the output frequency to account for different real-world conditions. This helps increase the accuracy and reliability of the oscillator in telecom applications, as the output frequency can be adjusted to compensate for variations in temperature, pressure, and other environmental factors.
The SIT9005ACE1D-28DK DDS oscillator is suitable for applications such as PTP (Precision Time Protocol) switching and synchronization, telecom high-speed timing systems, optical and analog networks, Satcom applications, OTDR (Optical Time Domain Reflectometer) systems and HD video switching. The oscillator also works well with software-defined radios and other precision, real-time applications such as modem timing and synchronization. In addition, the device is also useful for field and bench testing, as it can be remotely programmed via RS232 interface.
The most difficult part of using this device is controlling the output frequency. Unlike most oscillators, which require manual adjustment of frequency, the SIT9005ACE1D-28DK requires computer control. Setting the proper frequencies can be a challenge, but the company Tecan provides software code that can control the frequency output, making it easier to set the correct frequency. Additionally, the oscillator has a wide range of frequency adjustments, so it can be used for both high- and low-frequency applications.
Finally, SIT9005ACE1D-28DK DDS oscillators have proven to be a reliable precision oscillator suitable for various time-critical applications. Its adjustable-frequency output and low jitter performance make it an ideal choice for any system that requires precise timing synchronization. The device is cost-effective and its programmable frequency settings allow for better control over the output frequency, making it a valuable timing resource for telecom, data communications and other applications.
