Programmable Oscillators provide the flexibility of synthesizing many frequencies from only one reference frequency, such as from a crystal-based oscillator. They offer an alternative to crystal-based oscillators for applications that require a low-cost solution, an adjustable frequency, and a high degree of precision. The SIT9005ACB1D-25DN is a programmable oscillator which has an integrated crystal oscillator circuit, an analog-to-digital converter, a digital-to-analog converter and a programmable frequency-dividing unit. Its features make it applicable not just to high speed digital logic circuits, but also to low speed and real-time processing.

The SIT9005ACB1D-25DN is a low-cost solution for applications requiring set-frequency digital oscillator whose frequency can be modified without a major redesign project. It is ideal for applications where an adjustable frequency is desired while still retaining a high degree of accuracy. The ability to program the output frequency can be seen in both global and local designs. In a global design, the frequency can be set without any external referencing, while in a local design, the frequency can be adjusted based on a reference signal from an external device.

One of the main advantages of the SIT9005ACB1D-25DN is its precision. It is able to provide an accuracy range of ±50 ppm, which is higher than that of a crystal-based oscillator. Its low-power operation (drawing less than 130 mA at 5V) is also an advantage. The SIT9005ACB1D-25DN can operate over a wide range of temperatures and still retain a high degree of accuracy, making it attractive for applications that require tight frequency control over a wide temperature range.

The SIT9005ACB1D-25DN offers two operating modes - active and sleep. Three registers can be used to configure the oscillator’s behavior. The first register is used to select either active (normal) or sleep mode, while the second register can be used to choose between three frequency sources - crystal oscillator, internal or external clock. The last register can be used to adjust the output frequency from 0.5 MHz to 25 MHz.

The SIT9005ACB1D-25DN is able to precisely control a wide range of frequencies, making it applicable to various types of applications, such as clock recovery, phase detection and frequency synthesis. Its precision, low-power operation, high performance and efficient programmability make it an ideal solution for applications needing precision and versatility. The ability to quickly and precisely adjust the output frequency and control the operating mode makes the SIT9005ACB1D-25DN an attractive option for various types of applications, such as medical and industrial control and testing, communications and consumer electronics.
