Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD No Lead footprint matches the PCB layout design requirements. Cross-reference the part number suffix to confirm the exact packaging configuration.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for clock generation. Consider the 2.0x1.6 mm package size for space-constrained designs. Evaluate the need for standby functionality if power management is critical. Compare performance metrics such as phase noise and stability against application requirements using official specifications.

Oscillators Part Context

This model belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration. This family provides standard clock solutions for consumer and industrial electronics requiring precise timing signals.

Oscillators Replacement Considerations

Direct substitutes include other 25.0012 MHz LVCMOS oscillators with 1.8V supply and identical 2.0x1.6mm footprints. Verify pinout compatibility and electrical characteristics before substitution. Check manufacturer documentation for equivalent part numbers within the same product line.
