DS1077U-100

Overview

The DS1077U-100 is a dual-output fixed-frequency oscillator from the Maxim Integrated EconOscillator family, manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.75 V to 5.25 V and draws a typical supply current of 50 mA. The device generates output frequencies between 12.2 kHz and 100 MHz and functions reliably across an industrial temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, this component provides stable clock signals for digital systems without requiring external timing crystals or resonators.

Feature Summary

• Dual-output fixed-frequency oscillator configuration
• Integrated frequency range spanning 12.2 kHz to 100 MHz
• Single-supply operation at 5 V (4.75 V to 5.25 V)
• Compact 8-SOIC surface-mount package

Applications

• Microcontroller system clock generation
• Digital signal processing timing references
• Communication interface synchronization

Part Context

The DS1077U-100 belongs to the DS1077 series of EconOscillators, which are designed as drop-in replacements for discrete crystal oscillator circuits. This series eliminates the need for external tuning components, simplifying PCB layout and reducing bill-of-materials complexity for standard frequency requirements.

Replacement Considerations

Verify that the target application requires a fixed frequency rather than a programmable one. Ensure the 5 V supply rail matches the new design constraints. Confirm that the 8-SOIC footprint is compatible with the existing board space.
