DS1088LU-02A+W

Clock Generators, PLLs, Frequency Synthesizers Overview

The DS1088LU-02A+W is a fixed-frequency clock generator producing a square-wave output without external timing components. It operates on a 2.7V to 3.6V supply and features a power-down pin for power-sensitive applications. The device provides a factory-calibrated frequency of 2.048MHz with 1% tolerance over temperature and voltage. It utilizes an 8-pin µSOP package, includes a DNC pin internally connected to ground, and supports an operating temperature range from -20°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'A' against official documentation, as standard listings typically use 'DS1088LU-02+'. Confirm RoHS compliance status associated with the '+' designation. Check current availability as this component series may be subject to discontinuation or limited stock conditions.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for low-cost, fixed-frequency clock generation where minimal BOM count is critical. Ensure the load capacitance requirements (up to 50pF) are met by the target circuit. Verify that the 2.048MHz frequency aligns with system timing needs, as custom frequencies require direct factory consultation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the DS1088L EconOscillator family, designed to replace discrete crystals and ceramic resonators. It integrates the oscillator, prescaler, and control logic into a single CMOS IC, simplifying PCB layout and reducing assembly costs compared to traditional crystal-based solutions.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include DS1088LU-10+ (10.0MHz), DS1088LU-16+ (16.6MHz), and DS1088LU-66+ (66.6MHz). These share identical pinouts and electrical characteristics but differ in factory-set output frequency.
