• Embedded systems with low-voltage logic requirements

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout dimensions. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure joint integrity.

Oscillators Selection Notes

Select this component when a fixed 27.3067 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage as a primary constraint for power supply design. Evaluate the enable/disable feature if power efficiency during standby modes is critical. Compare physical dimensions against available board space constraints.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which focuses on standard frequency outputs for general-purpose timing applications. The manufacturer has extensive experience in quartz crystal production, providing reliability for industrial and commercial use cases.
