Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's official datasheet to ensure compatibility with the target design. Confirm that the 1.8V supply requirement aligns with the system's power rails. Check for any specific handling or storage requirements detailed in the product documentation before integration.
Selection Notes
Select this component when a 64.000 MHz clock source is required with LVCMOS compatibility. Ensure the design supports the 1.8V operating voltage and can accommodate the 4-SMD no-lead footprint. Consider the enable/disable feature if power management during idle states is necessary for the application.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co. Ltd. The series offers various frequencies and voltage options within a small form factor. The 18QHTF21-64.000-OE specifically targets applications needing a precise 64 MHz clock signal with low power consumption capabilities.
Replacement Considerations
Direct substitutes may include other 64.000 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package from different manufacturers, provided they match the 1.8V supply and pinout configuration. Verify electrical specifications and thermal characteristics before substitution.
