Procurement Notes
Verify the specific ordering suffix matches the required frequency and package variant. Confirm that the supplier provides official datasheets detailing electrical characteristics and reliability data. Ensure compatibility with the target system's voltage levels and interface requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-profile oscillator is required for 1.8V logic systems. Consider the 2.0x1.6mm footprint for tight space constraints. Evaluate the need for power-down functionality to extend battery life in portable applications. Verify that the LVCMOS output meets the input specifications of the connected load.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature crystal oscillators. The series typically offers various frequencies and voltage options within a standardized small outline package format. Mercury Electronics specializes in frequency control products, including quartz crystals and oscillators, serving global electronics markets.
Replacement Considerations
Direct substitutes include other 13.5168 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and physical dimensions before swapping. Alternative parts must support the same power-down feature if required by the design.
