Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a stable 25.006 MHz clock source is required for LVCMOS-compatible devices. The choice is driven by the need for a low-profile surface-mount solution with power-down capabilities. Consider the 1.8V supply constraint and ensure the application does not require higher voltage levels or different output logic families such as HCMOS or LVDS.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics 18QHTF series, designed for high-frequency timing applications. The manufacturer specializes in quartz crystals and oscillators, offering various packages and frequencies. This specific model represents a standard XO variant optimized for space-constrained designs requiring reliable clock signals.

Oscillators Replacement Considerations

Direct substitutes must match the 25.006 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers' equivalent series ensuring identical electrical parameters and mechanical dimensions.
