The DS1090U-2/V+T from Maxim Integrated is a versatile, low-frequency, spread-spectrum EconOscillator™ designed to reduce electromagnetic interference (EMI) at the source. This innovative component is an ideal solution for applications that require a cost-effective method to improve system-level EMI performance. It is especially beneficial in environments where stringent EMI regulations are in place.

The DS1090U-2/V+T operates by modulating the output frequency to decrease the peak spectral energy of the fundamental and harmonic frequencies, spreading it over a wider bandwidth. This spread-spectrum modulation makes the overall EMI signature less concentrated and easier to filter, allowing for improved EMI compliance without the need for additional costly shielding or filtering components.

This device is highly configurable and features a user-programmable dither percentage and modulation rate, enabling designers to optimize the spread-spectrum profile for their specific application. The EconOscillator™ can generate frequencies from 130kHz to 66.6MHz, with the DS1090U-2/V+T variant specifically offering an output frequency range that is particularly suited for various low-frequency applications.

The DS1090U-2/V+T is available in a compact, 8-pin µSOP package, making it an ideal choice for space-constrained applications. It requires no external components for operation, simplifying the design process and reducing the bill of materials. The device is also fully integrated, meaning that it contains both the spread-spectrum control circuitry and the oscillator in a single chip, further streamlining the design and manufacturing process.

With its combination of spread-spectrum capability, configurability, and compact packaging, the DS1090U-2/V+T from Maxim Integrated is a powerful solution for engineers looking to enhance system EMI performance while maintaining design simplicity and cost-effectiveness.
