DS1099U-BC

Clock Generators, PLLs, Frequency Synthesizers Overview

The DS1099U-BC is a low-frequency dual EconOscillator clock generator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 145 uA. The device features two outputs with a maximum output frequency of 2 Hz and supports input frequencies up to 1.048 MHz. It is housed in an USOP-8 package, suitable for surface mount installation, and functions reliably across an extended temperature range from -40°C to +125°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notices or obsolescence alerts prior to procurement planning. Ensure packaging specifications match assembly requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the DS1099U-BC when dual low-frequency outputs are required within a compact footprint. Verify that the 2 Hz maximum output frequency meets system timing needs. Ensure the 2.7 V to 5.5 V supply range aligns with available power rails. Consider the USOP-8 package constraints during PCB layout design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the DS1099U series of low-frequency oscillators. It shares core architectural similarities with variants like the DS1099U-WZ+ and DS1099U-CC+, differing primarily in suffix designations which may indicate specific temperature grades, packaging options, or compliance certifications rather than functional changes.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other DS1099U series variants such as DS1099U-WZ+ or DS1099U-CC+. Verify pin compatibility and electrical parameters before substitution. No alternative part numbers are explicitly confirmed as direct replacements in public documentation.
