Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm the 4-SMD package dimensions fit the PCB layout constraints. Check for RoHS compliance status if required by project specifications.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated standby feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD footprint for space-constrained layouts. Verify that the 25.8048 MHz frequency meets the system clock requirements without additional dividers.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration, though exact details require datasheet verification. Mercury Electronics specializes in quartz crystal components.

Oscillators Replacement Considerations

Direct substitutes must match the 25.8048 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functions. Ensure frequency stability specs meet original design margins.
