Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm that the 4-SMD no-lead package dimensions fit the PCB footprint constraints. Cross-reference the part number suffix to ensure compatibility with required operating temperature ranges.

Selection Notes

Select this component when a 65.36 MHz reference is required for LVCMOS-compatible logic families. Consider the 1.8V supply constraint and the need for a power-down feature. Evaluate the thermal performance within the specified operating temperature range. Compare package size against available board space to ensure proper placement and soldering reliability during manufacturing.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products.
