Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the exact enable/disable pin configuration and output drive strength. Ensure the 1.8V supply requirement aligns with the target circuit's power rails. Confirm the 4-SMD footprint dimensions match the PCB layout constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 17.5025 MHz timing source is required for 1.8V logic families. The ±50 ppm stability suits applications tolerant of moderate frequency drift. Consider the enable feature if power management or clock gating is necessary within the design architecture.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for general-purpose timing applications. The 18QHTF21 series typically offers standard performance levels suitable for consumer electronics and industrial control modules where space efficiency and low voltage operation are prioritized over high-frequency precision.

Oscillators Replacement Considerations

Direct substitutes must match the 17.5025 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify that any alternative component supports the same enable/disable control mechanism and meets the ±50 ppm stability requirement to ensure functional equivalence.
