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 constraints. Request the official datasheet to validate operating temperature ranges and electrical characteristics for the intended application environment.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 13.514 MHz timing. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small 2.0x1.6 mm package size for space-constrained layouts. Verify compatibility with LVCMOS logic levels in the receiving circuitry.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystals and oscillators, offering various packages and frequencies. This specific model represents a surface-mount option designed for modern electronic devices requiring reliable timing signals.

Replacement Considerations

Direct substitutes must match the 13.514 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check equivalent models from other manufacturers for identical pinout and electrical specifications. Verify thermal performance and stability across the same temperature range.
