Procurement Notes
Verify the specific suffix OE against the manufacturer's current datasheet to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement aligns with the target design. Confirm the 4-SMD package footprint matches the PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a 79.075 MHz frequency is required within a 2.0x1.6 mm form factor. Consider the 1.8V operating voltage constraint during power budgeting. Evaluate the LVCMOS output drive strength against load requirements. Verify that the enable/disable feature meets system power management needs.
Part Context
This part belongs to the 18QHTF21 series of surface mount crystal oscillators from Mercury Electronics. The series offers various frequencies with standardized packaging. The OE suffix typically denotes specific ordering or compliance variations. Mercury Electronics specializes in quartz-based timing solutions including crystals and oscillators.
Replacement Considerations
Check for direct substitutes such as the 18QHTF21-79.075-PD variant if available. Ensure any replacement maintains the 79.075 MHz frequency, 1.8V voltage, and 4-SMD package dimensions. Verify pinout compatibility and electrical specifications match exactly.
