The device supports a supply voltage from 2.25 V to 3.6 V and features CMOS output format. It is housed in a 6-SMD, No Lead package with dimensions of 5.00 mm x 3.20 mm x 0.90 mm. The component functions across an operating temperature range of -55°C to +125°C.

Feature Summary

• Utilizes silicon MEMS technology for reliable clock generation
• Supports programmable frequency configuration within specified range
• Features enable/disable functionality for power management

Applications

• General clock source for embedded systems
• Timing reference for digital signal processing circuits
• Clock generation for communication interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm that the ±10 ppm stability rating aligns with system timing requirements. Ensure the operating temperature range covers the intended environmental conditions. Cross-reference the datasheet for pinout compatibility during integration.

Selection Notes

Select this component when a wide industrial temperature range and high frequency stability are required. Compare against other DSC8121 variants if different stability or package options are needed. Consider the CMOS output interface compatibility with the target load capacitance. Evaluate power consumption specifications against system battery life constraints.

Part Context

This part belongs to the DSC8121 series of unprogrammed MEMS oscillators. It shares the same core technology and package form factor as other models in the family, such as the DSC8121BI2 and DSC8121DM2. The primary distinction lies in the specific frequency stability rating and operational temperature limits defined for this variant.

Replacement Considerations

DSC8121BM5 is the non-tape version of this component. DSC8121BI2 offers similar performance but with different stability and temperature ratings. Verify package dimensions and electrical characteristics before substituting with other MEMS oscillator models.
