Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints. Check for any specific soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a 26.4 MHz frequency is required with LVCMOS outputs. The 1.8V supply voltage makes it suitable for modern low-power applications. The integrated standby feature offers energy savings during idle periods. The small SMD package aids in space-constrained designs. Verify compatibility with the host circuit's input impedance and drive strength requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized 2.0x1.6mm footprint. The 'PD' suffix likely indicates a specific packaging or tape-and-reel configuration, though exact details require datasheet confirmation. These components are designed for general-purpose timing applications.

Oscillators Replacement Considerations

Direct substitutes must match the 26.4 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering similar low-profile oscillators. Ensure pinout compatibility if pin assignments differ among alternatives. Verify that replacement parts meet the same electrical specifications and mechanical dimensions.
