Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency tolerance and temperature range match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint corresponds to the 2.0x1.6mm SMD package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for the clock source. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 2.0x1.6mm package size for space-constrained designs. Verify that the enable pin functionality meets the system's power sequencing needs.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard crystal oscillators for various timing applications. The manufacturer specializes in quartz crystals and frequency control products, offering components like TCXOs and VCTCXOs alongside standard oscillators for diverse electronic market needs.

Oscillators Replacement Considerations

Direct substitutes must match the 38.13986 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference other manufacturers' offerings with identical electrical specifications and mechanical dimensions to ensure functional interchangeability without redesigning the host circuit.
