Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Cross-reference the part number suffix to ensure the correct packaging and tape-and-reel specifications are obtained from authorized distributors.

Oscillators Selection Notes

Select this component when a precise 25.76 MHz reference is required for digital circuits operating at 1.8V. Consider the small 2.0x1.6mm form factor for space-constrained designs. Evaluate the need for power-down capabilities if battery life optimization is critical. Compare performance metrics such as phase noise and stability against other oscillators in the same family to ensure compatibility with your signal integrity requirements.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series is characterized by its small footprint and low voltage operation. The 'PD' suffix typically indicates the inclusion of power-down control features. This specific variant provides a fixed frequency output suitable for synchronizing data transmission and processing elements in modern electronic systems.

Oscillators Replacement Considerations

Direct substitutes within the same Mercury Electronics QHTF series may be available with different frequencies or voltages. Verify pin compatibility and electrical characteristics before swapping. Other manufacturers offering 4-SMD LVCMOS oscillators at 1.8V should be evaluated for equivalent size and performance. Ensure that any replacement supports the required standby function and maintains similar thermal and electrical specifications.
