Maxim Integrated DS1090U-8+ Low-Frequency Spread-Spectrum EconOscillator™

The DS1090U-8+ is a versatile, low-frequency, spread-spectrum EconOscillator™ designed by Maxim Integrated to provide a cost-effective solution for reducing electromagnetic interference (EMI) in various electronic applications. This precision silicon oscillator generates a dithered clock output, which effectively spreads the energy of the fundamental and harmonic frequencies over a broader frequency band, thereby minimizing EMI at any single frequency.

One of the key features of the DS1090U-8+ is its programmability. With an integrated, programmable nonvolatile (EEPROM) spread percentage and output frequency, this device can be tailored to meet the specific requirements of your application. The spread percentage can be selected from 0% to 8%, allowing for a fine-tuned approach to EMI reduction. The output frequency range is also adjustable, further enhancing its flexibility.

Designed to operate from a 3.3V supply voltage, the DS1090U-8+ is ideal for low-voltage applications. Its low-power consumption makes it suitable for portable and battery-powered devices. Moreover, it is available in a compact 8-pin µSOP package, which is beneficial for space-constrained designs.

The DS1090U-8+ is easy to integrate into existing designs, thanks to its simplicity and the need for only an external resistor to set the output frequency. This feature simplifies the design process and reduces the overall component count, which can lead to cost savings in both materials and assembly.

Applications for the DS1090U-8+ are diverse and include but are not limited to telecommunications, consumer electronics, and industrial systems where EMI compliance is critical. By using this EconOscillator™, designers can achieve the desired EMI performance without resorting to costly shieldings or filtering components.

In summary, the DS1090U-8+ from Maxim Integrated is a reliable and efficient solution for managing EMI in electronic systems. Its programmability, low power consumption, and ease of use make it an excellent choice for a wide range of applications where EMI could pose a challenge.
