SIT1602ACL2-25E

Programmable Oscillators are widely used to generate precision sinusoidal signals at specific frequencies. The SIT1602ACL2-25E is a highly efficient oscillator in this category. It is a low-cost, low-power programmable oscillator which provides excellent performance for frequency synthesis applications.

Application Field

The SIT1602ACL2-25E should be used in applications that require high accuracy, low cost, low power and small size. It is designed primarily for use with digital logic and FPGAs. The frequency stability is superior to that of conventional oscillators, providing a reliable frequency source for use in precision test and measurement systems. Additionally, the SIT1602ACL2-25E can be programmed to operate at any frequency in its range without requiring any additional external components. This makes it ideal for use in clock and timing applications.

Working Principle

The SIT1602ACL2-25E is based on a programmable oscillator technique which takes advantage of a state-of-the-art LC oscillator circuit. The oscillator is then modified with a parallel capacitance array to adjust the oscillation frequency. This is done by selectively connecting/disconnecting the capacitors based on the user-configured frequency. By adjusting the capacitance, the oscillator frequency can be precisely controlled, offering a frequency stability of 10 parts-per-million (PPM).

The frequency accuracy of the SIT1602ACL2-25E is further enhanced by the addition of a step-lock circuit. This circuit keeps the oscillator frequency locked, even when the supply voltage or temperature drifts significantly. The step-lock circuit also allows the SIT1602ACL2-25E to be used as a direct replacement for conventional quartz oscillators.

The SIT1602ACL2-25E is designed to provide excellent performance in a cost effective package. It operates from 1.8V to 3.3V, making it ideal for embedded applications. It is also RoHS compliant, further extending its utility in a variety of systems.

The SIT1602ACL2-25E is an ideal affordable oscillator for any application that requires precise and reliable frequency control. Its highly efficient design and integrated step-lock circuit make it a perfect choice for designs where reliability and repeatability are required.
