Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm the enable/disable pin configuration matches your control logic to ensure proper operation during standby or active modes.

Selection Notes

Select this component when a precise 75.463 MHz clock source is required with low voltage operation. Consider the enable/disable feature if power efficiency is critical. Verify that the LVCMOS output compatibility matches the input requirements of the downstream digital components in your design.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies with standard LVCMOS outputs. The 18QHTF21 variant specifically denotes the package type and form factor within the manufacturer's product line, designed for space-constrained electronic assemblies.

Replacement Considerations

Direct substitutes include other 75.463 MHz LVCMOS oscillators with 1.8V supply and similar footprint. Check datasheets for compatible parts from manufacturers like Epson or SiTime. Ensure electrical parameters such as phase noise and jitter meet or exceed original specifications.
