Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and thermal performance specifications to ensure reliable operation under intended environmental conditions.

Selection Notes

Select this model when a 74.92 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for low-power portable devices. Consider the enable pin feature if dynamic power management is necessary. Verify that the 4-SMD form factor meets space limitations. Compare alternative frequencies from the same series if the exact 74.92 MHz rate is not strictly mandated by the application protocol.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard frequencies. The series typically features LVCMOS outputs and support for different supply voltages.
