Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout silkscreen and pad dimensions. Cross-reference the part number suffix PD with manufacturer documentation to confirm availability and lead times through authorized distributors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The choice depends on the need for a small form factor via the 4-SMD package. Consider the standby feature if power efficiency is critical. Verify that the 19.66089 MHz frequency meets the exact timing specifications of the application without requiring external dividers or multipliers.
