Oscillators Procurement Notes

Verify the specific ordering suffix 'R13' confirms tape-and-reel packaging requirements against your assembly line specifications. Ensure the 27 MHz frequency and ±50 ppm stability align with system timing budgets. Confirm that the 3.3V nominal voltage matches the target board power rail. Validate that the 2.5x2.0 mm footprint fits the designated PCB land pattern without clearance issues.

Oscillators Selection Notes

Select this model when AEC-Q100 certification is mandatory for automotive compliance. Choose this variant over lower-stability parts if the system requires ±50 ppm accuracy under extreme thermal conditions. Opt for this MEMS solution to replace quartz oscillators where physical robustness against shock and vibration is critical. Ensure the LVCMOS/LVTTL output logic levels are compatible with the receiving digital interface.
