Procurement Notes
Verify the specific suffix against official documentation to confirm functional differences. Ensure the ordering part number matches the required enable/disable configuration and voltage specifications. Cross-reference the manufacturer's latest datasheet for accurate electrical parameters before integration into design schematics.
Selection Notes
Select this component when a low-voltage LVCMOS output is required for high-frequency timing applications. The enable/disable feature allows for dynamic power management in battery-operated or energy-efficient designs. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a small form factor. The -OE suffix indicates a specific configuration variant within this product line, distinct from other suffixes like -PD which may denote standby modes.
Replacement Considerations
Consult the manufacturer's substitution guide for verified alternatives. Ensure any replacement part matches the 87.654 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify that the substitute component also supports the Enable/Disable control function if required by the circuit design.
