Procurement Notes
Verify the specific ordering suffix to confirm the exact frequency, stability, and package variant required for your design. Ensure the selected part matches the necessary operating temperature range and supply voltage specifications. Confirm that the blank programming state aligns with your production workflow for enabling the oscillator. Check current availability status as lead times may vary based on manufacturing schedules.
Selection Notes
Select this component when a compact, low-power programmable clock source is needed for high-speed data interfaces. The ±10ppm stability suits precision timing requirements in networking equipment. Consider the 6-SMD package for space-constrained PCB layouts. Compare against other series members if higher frequencies or different stability levels are required.
Part Context
This part belongs to the DSC8121 family of programmable MEMS oscillators. These devices replace traditional quartz crystals with silicon-based solutions, offering better shock resistance and smaller form factors. The family provides flexibility in frequency selection through user programming, reducing inventory complexity for manufacturers deploying multiple clock speeds.
Replacement Considerations
DSC8121AL2: Similar package but different stability/frequency range. DSC8121CM1: Smaller 3.2x2.5mm package. DSC8121DI2: Different package type. Verify electrical parameters before substitution.
