Procurement Notes
Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific handling instructions regarding ESD sensitivity during assembly.
Selection Notes
Select this component when a low-voltage, small-footprint oscillator is required for applications needing a 67.596 MHz reference. Consider the LVCMOS interface compatibility with your target microcontroller or FPGA. Evaluate the power consumption benefits of the standby mode if battery life is a critical factor in the end product design.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package. These components are designed to replace larger through-hole crystals or larger SMD packages in space-constrained modern electronic designs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users should consult official distributor databases for cross-reference information or contact the manufacturer directly for compatible alternatives.
