Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct voltage and package configuration. Confirm that the OE suffix aligns with the required enable/disable functionality and LVCMOS output type. Cross-reference the part number with official Mercury Electronics catalogs to validate availability and technical specifications before procurement.

Oscillators Selection Notes

Select this component when a precise 25.92 MHz reference is required for LVCMOS-compatible digital circuits. Ensure the system design supports a 1.8V supply rail. Consider the enable/disable feature if power efficiency during inactive states is a critical design parameter. Verify footprint compatibility with the 4-SMD no-lead package dimensions.

Oscillators Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, which focuses on small-form-factor surface-mount devices. The series typically offers various frequencies and voltage options. The 18 prefix indicates the 1.8V operating voltage variant, while the 21 likely denotes the package or series code. This model serves as a timing source for synchronous digital systems.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-25.920-PD from the same manufacturer, which shares identical electrical characteristics and package type. Ensure any replacement maintains the LVCMOS output logic and 1.8V supply requirement. Verify pinout compatibility for the 4-SMD no-lead configuration.
