Procurement Notes
Verify the specific suffix against official documentation to confirm electrical characteristics and pinout configuration. Ensure the ordering part number matches the required frequency and package type exactly. Cross-reference manufacturer specifications for environmental ratings and reliability data before finalizing procurement decisions.
Selection Notes
Select this component when a low-voltage LVCMOS output is required for high-frequency timing applications. Consider the enable/disable feature for power-sensitive designs. Verify that the 4-SMD no-lead package dimensions fit the available PCB space and thermal requirements of the target application environment.
Part Context
This oscillator belongs to the Mercury Electronics 18QHTF series, which provides various frequency options within a standardized small footprint. The series supports multiple supply voltages and output types, allowing designers to maintain consistent mechanical footprints across different product lines while adjusting electrical parameters.
Replacement Considerations
Direct substitutes include other 83.125 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pin compatibility and voltage levels when considering alternatives from the same family, such as variants with different suffixes.
