DS1090U-8+ Description

Short technical summary and product information.

The DS1090U-8+ is a low-cost, dithered oscillator designed for applications requiring reduced peak-radiated emissions, such as switched-mode power supplies, servers, printers, embedded microcontrollers, and industrial controls. This spread-spectrum EconOscillator™ features user-programmable output frequencies from 125kHz to 8MHz, with the specific DS1090U-8+ model covering 500kHz to 1MHz.

 

Key electrical specifications include a wide operating voltage range of 3.0V to 5.5V and CMOS/TTL-compatible outputs. The device allows for programmable dither percentage from 0% to 8% and programmable dither rates. It operates within an industrial temperature range of -40°C to +85°C.

 

The DS1090U-8+ is available in an 8-uMAX/uSOP surface-mount package. Its design integrates a resistor-programmed master oscillator, a factory-programmed clock prescaler, and a pin-programmed dither circuit, simplifying implementation for spread-spectrum clock generation needs.
