Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official documentation to confirm the Enable/Disable function and exact electrical parameters. Ensure the required frequency of 17.734454 MHz matches the system design requirements. Confirm that the 1.8V supply voltage and LVCMOS output levels are compatible with the target load circuit before procurement.

Oscillators Selection Notes

Select this component when a precise 17.734454 MHz clock source is required for low-voltage digital circuits. The choice depends on the necessity for the specific 2.0x1.6mm footprint and the requirement for active enable/disable control. Consider the -40°C to 85°C industrial temperature range suitability for the intended operational environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The '18QHTF21' prefix indicates the standard XO form factor, while the numeric suffix denotes the specific frequency. This model represents a specific variant optimized for 1.8V operation.

Oscillators Replacement Considerations

Direct substitutes must match the 17.734454 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package dimensions. Verify pinout compatibility and thermal characteristics. Other suffixes like '-PD' indicate different control functions and are not direct functional replacements without circuit modification.
