Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a precise 10.752 MHz reference is needed in space-constrained designs. The 1.8V operation makes it suitable for modern low-power digital interfaces. Consider the enable pin requirement if dynamic power saving is necessary. Compare performance against other Mercury Electronics XO series parts for similar form factors.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies within a standardized small outline package. Mercury Electronics has been active in the frequency control industry since 1973, providing components for global electronic markets.
Replacement Considerations
Direct substitutes may include other 10.752 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with Mercury Electronics' own product line for alternative frequencies or voltages.
