Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 2.0x1.6mm footprint matches the PCB design constraints. Check for any specific operating temperature range limitations required by the application environment.

Selection Notes

Select this component when a 72.727 MHz clock source is required with low voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. The small form factor suits space-constrained designs. Verify that the enable pin functionality meets power efficiency needs compared to always-on alternatives.

Part Context

This part belongs to the 18QHTF series of oscillators from Mercury Electronics. The series typically offers various frequencies and package sizes. The 'OE' suffix indicates the presence of an enable control pin. This model specifically targets applications requiring precise timing at 72.727 MHz with minimal board space usage.

Replacement Considerations

Direct substitutes include other 72.727 MHz LVCMOS oscillators in 2.0x1.6mm packages. Verify pinout compatibility and electrical specifications such as jitter and phase noise. Cross-reference with similar models like 18QHTF21 variants from the same manufacturer or compatible industry-standard equivalents.
