Maxim Integrated DS1086LU-21D+ Programmable Oscillator

The DS1086LU-21D+ is a versatile and programmable oscillator from Maxim Integrated, designed to offer a high degree of flexibility and precision for a wide range of applications. This innovative component is capable of generating frequencies from 260kHz to 133MHz without the need for external resistors or capacitors, simplifying the design process and reducing the overall component count in your circuit.

At the heart of the DS1086LU-21D+ is Maxim's proprietary Spread-Spectrum EconOscillator™ technology, which allows for frequency adjustment over a wide range with a simple serial interface. This feature is particularly useful for reducing electromagnetic interference (EMI), making the device an excellent choice for applications where EMI compliance is critical, such as telecommunications, networking, and consumer electronics.

The oscillator's frequency is programmable through an I²C-compatible serial interface, enabling on-the-fly adjustments without the need for hardware modifications. This programmability is essential for systems that require dynamic frequency management or need to operate at multiple frequency points.

Additionally, the DS1086LU-21D+ offers a spread-spectrum feature that can be enabled or disabled according to the needs of the application. When activated, this feature modulates the output frequency to further minimize EMI, which is particularly beneficial in densely packed PCBs where signal integrity can be a concern.

With its 3.3V supply voltage and low power consumption, the DS1086LU-21D+ is also an energy-efficient choice for portable and battery-operated devices. Its compact 8-pin µSOP package makes it suitable for space-constrained applications, ensuring that it can be integrated into designs without requiring significant board real estate.

In summary, the Maxim Integrated DS1086LU-21D+ programmable oscillator is a high-performance, flexible solution for generating precise frequencies while minimizing EMI. Its ease of use, combined with its power efficiency and small form factor, makes it an ideal choice for a multitude of electronic applications.
