Programmable oscillators are special oscillator devices that are designed to provide highly accurate timing signals. The SIT9005ACA2D-28NL oscillator is a perfect example of such a device. This oscillator is designed specifically to provide highly accurate, low-jitter, frequency agile timing signals in a wide range of applications.

The SIT9005ACA2D-28NL is a 4-pin oscillator with a frequency output range from 1 Hz to 80 MHz, adjustable via a serial I2C interface. The oscillator has an output jitter of 1ps (typical) and integrates an oscillator core, an I2C interface and a frequency-hopping algorithm with programmable frequency steps. This oscillator supports frequency control modes with variable step sizes as well as frequency control modes that use fixed time-delay periods.

The SIT9005ACA2D-28NL is ideal for a wide range of applications, including clock and timing management, board synchronization, and system synchronization. This oscillator is highly suitable for a variety of communication protocols such as Ethernet, USB, PCI Express and SATA. This oscillator can also be used to provide precision timing for RF synthesisers, where precise frequency control is necessary.

The SIT9005ACA2D-28NL works by using a frequency-hopping algorithm to sequentially change the frequency at precise intervals. The algorithm is programmed by loading a list of frequencies into the oscillator memory or memory map. The oscillator then uses this frequency-hopping algorithm to step through the frequency list and generate the precise timing signals required.

The SIT9005ACA2D-28NL also has an embedded temperature compensation feature. This feature ensures that over a wide operating temperature range, the oscillator maintains precise frequency and jitter performance. This feature also helps to reduce clock errors caused by temperature variations and improves system accuracy and reliability.

The SIT9005ACA2D-28NL also has an advanced power management system which is designed to minimise power consumption. The oscillator automatically reduces power consumption when it is running in low load conditions, and when no start-up or operation current is needed. This feature helps to reduce system power consumption and prolongs battery life.

Overall, the SIT9005ACA2D-28NL oscillator is a highly reliable and accurate device. Its features make it ideal for a wide range of applications requiring precision timing signals. Its frequency agility, low jitter, temperature compensation and power management features make it an essential tool for any system requiring precise timing control.
