Procurement Notes
Verify the specific suffix 'I2' against official Microchip documentation to confirm package type and pinout compatibility. Ensure the selected variant matches the required LVPECL output format and voltage range. Confirm that the blank programming state aligns with the intended system integration workflow before finalizing procurement orders.
Selection Notes
Select this component when an LVPECL interface is required within the specified frequency range. Consider the 6-SMD package dimensions for PCB layout constraints. Verify that the ±25ppm stability meets the system timing requirements. Ensure the operating temperature range covers the expected environmental conditions of the target application.
Part Context
This part belongs to the DSC8122 series of programmable oscillators. It shares the family's MEMS architecture but differs in output format and package compared to other variants like the CMOS-output DSC8121. The series provides flexible clock solutions for various high-performance applications.
Replacement Considerations
Check for direct substitutes within the DSC8122 series that match the LVPECL output and 6-SMD package. Verify if alternative packages or output formats are acceptable for the design. Consult official substitution guides for confirmed compatible replacements.
