Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Cross-reference the part number suffix PD to ensure correct packaging specifications are met for manufacturing integration.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for clock generation. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the LVCMOS output level if interfacing with standard digital logic families. Verify thermal performance within the specified operating temperature range for the intended application environment.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics 18QHTF21 series, which offers various standard frequencies. The series provides options for different supply voltages and output types. The 41.666 MHz variant serves as a specific timing reference point within the broader product lineup, maintaining consistent package dimensions and operational characteristics across the family.

Oscillators Replacement Considerations

Direct substitutes may include other 41.666 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure equivalent supply voltage and output drive strength. Verify pinout compatibility and thermal characteristics. Check for any differences in phase noise or jitter specifications if high precision is required.
