Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards. Validate the part number suffix PD indicates the correct packaging configuration for your assembly line.

Selection Notes

Select this oscillator when a 13.2256 MHz reference is required with minimal power draw. Consider the LVCMOS output level for compatibility with downstream logic gates. Evaluate the small form factor suitability for space-constrained designs. Compare performance against other Mercury XO series parts if different frequencies or voltages are needed. Ensure the operating temperature range meets your environmental specifications.
