Oscillators 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 4-SMD no-lead package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the power-down pin configuration with your schematic.

Oscillators Selection Notes

Select this component when a stable 16.768 MHz reference is needed for LVCMOS interfaces. Consider the 1.8V operating voltage as a primary constraint for power-sensitive designs. The integrated power-down feature makes it suitable for battery-operated applications where standby current reduction is critical. Evaluate the small 2.0x1.6mm package size for space-constrained layouts compared to larger oscillator packages.
