Programmable Oscillators are used in situations where an oscillator with a precisely determined frequency is needed. The SIT9005ACE2D-18NC is one such oscillator, designed for telecommunications applications. It is a low cost, easy to use unit that offers superior frequency stability, superior reliability, and integrates an inter\'s internal components into one submodule.

The SIT9005ACE2D-18NC supports a variety of communications applications, including SONET/SDH, E1, GSM, and ADSL. It features a maximum frequency of 254 MHz and an input frequency range of 6 MHz to 240 MHz. The oscillator utilizes a PLL based, digital divider and phase locked loop to generate an accurate, adjustable clock frequency from 6 to 204 MHz, with an adjustable output frequency from 156 - 254 MHz. Additionally, the output frequency can be adjusted to meet the requirements of any system using a wide variety of communications applications.

The working principle of the SIT9005ACE2D-18NC is based on a phase-locked loop. This is a type of negative feedback system that locks a signal to a reference phase. The SIT9005ACE2D-18NC utilizes this technique to control the output frequency of the oscillator. First, the input frequency is received by the oscillator, and after a series of frequency divider and phase locked loop operations, the output frequency is generated. This output is compared to the reference phase to identify any differences, and the system then adjusts the output frequency until it is in line with the reference phase. This adjustment process continues to ensure that the output frequency remains stable and precise.

The SIT9005ACE2D-18NC are designed to be used in communication applications that require a high degree of frequency accuracy and stability, such as in telecom networks, radio communications, multimedia, and other broadcast applications. The oscillator can be programmed to generate a specific frequency, due to its digital stepsize based PLL design. Moreover, the oscillator can be used in a wide array of digital and analog systems, making it a reliable, cost-effective solution for many applications.

In addition to its robust frequency accuracy and stability, the SIT9005ACE2D-18NC also has a wide temperature range of -40°C to +85°C and a low ripple of approximately 0.5ps RMS. This ensures that the oscillator can operate in a range of environments, making it an ideal choice for applications where temperature or environmental conditions may vary significantly. It also provides a reliable, stable output in a wide variety of operational conditions.

The SIT9005ACE2D-18NC is an ideal solution for applications that require a reliable, accurate, and stable oscillator.
