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 package footprint matches the PCB layout requirements. Check for any specific handling instructions related to the no-lead surface mount construction.

Oscillators Selection Notes

Select this component when a precise 26.796 MHz timing source is required within a low-voltage 1.8V environment. The LVCMOS output ensures direct interfacing with standard logic families without additional level shifting. The integrated power-down feature allows for energy management in battery-operated or power-sensitive designs. Consider the physical size constraints due to the 2.0x1.6mm package.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and package dimensions. The 'PD' suffix indicates the inclusion of a power-down pin functionality. These oscillators are designed for applications demanding reliable clock signals in space-constrained environments.

Oscillators Replacement Considerations

Direct substitutes must match the 26.796 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent performance specifications including jitter and stability parameters. Cross-reference with other manufacturers offering similar SMD oscillators if Mercury Electronics parts are unavailable.
