- Includes hardware enable/disable control functionality
Applications
- High-speed data communication interfaces
- Industrial automation systems
- Consumer electronics requiring precise timing
Procurement Notes
Verify the specific suffix 'BI2' against official Microchip documentation to confirm the exact temperature range (-40°C to +85°C), frequency stability (±25 ppm), and package dimensions. Ensure compatibility with the target system's voltage levels and I2C programming requirements before integration.
Selection Notes
Select this component when a small form factor is required alongside programmable flexibility. It is suitable for designs needing CMOS outputs and moderate stability. Compare against the DSC8121AI2 or DSC8121AL2 if different temperature ranges or package sizes are necessary for the application.
Part Context
This part belongs to the DSC8121 series of programmable MEMS oscillators. It shares the same core architecture as other variants in the family but differs in packaging, temperature rating, and stability specifications. The series offers a drop-in replacement for traditional crystal oscillators with enhanced configurability.
Replacement Considerations
Publicly confirmed substitutes include DSC8121AI2 and DSC8121AL2. Verify pinout compatibility and electrical parameter alignment, particularly regarding operating temperature limits and frequency stability, when substituting these parts.
