Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging configuration distinct from tube variants. Confirm that the blank programming state requires external initialization before operation. Ensure the selected frequency falls within the 10 MHz to 170 MHz operational limits defined for this specific part number.
Selection Notes
Select this component when a small form factor is required alongside programmable frequency capabilities. Consider the CMOS output compatibility with downstream digital logic circuits. Evaluate the 2.25V to 3.6V supply range against system power rails to ensure proper operation without additional level shifting.
Part Context
This part belongs to the DSC8121 series of programmable MEMS oscillators. It shares core specifications with other suffixes like CM5 but differs in packaging format. The series offers flexibility in frequency selection while maintaining low power consumption profiles suitable for portable and space-constrained electronic designs.
Replacement Considerations
Direct substitutes include other DSC8121 series variants such as DSC8121CM5 or DSC8121CM1, provided the packaging difference between tape and reel versus tube is acceptable for the assembly process. Verify pinout compatibility and electrical parameters match the design requirements.
