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 footprint matches your PCB layout constraints. Request official datasheets from authorized distributors to validate manufacturing specifications and quality certifications.

Selection Notes

Select this oscillator when a stable 80.1 MHz clock source is required for LVCMOS-compatible digital interfaces. Consider the low profile and small footprint for space-constrained designs. Evaluate the enable/disable feature if power efficiency during idle states is critical. Compare performance metrics such as phase noise and stability against alternative solutions in the same package type.

Part Context

This component belongs to the 18QHTF21 series of standard quartz oscillators from Mercury Electronics. The series offers various frequencies within a consistent 2.0x1.6mm SMD form factor. These devices are engineered for reliability in consumer electronics and industrial applications. The 'OE' suffix typically denotes specific packaging or testing configurations defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the 80.1 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before substitution. Consult manufacturer cross-reference lists for approved alternatives.
