Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a stable 45.576 MHz clock source is required for LVCMOS-compatible digital circuits. Consider the 1.8V operating voltage as a primary constraint for power-sensitive applications. Evaluate the need for standby capabilities if power conservation is critical. Compare physical dimensions against available board space to ensure the 2.00mm x 1.60mm package fits within the designated area without interference.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, designed for surface-mount applications. The series typically offers various frequencies and voltage options. This specific model provides a standard XO solution with integrated power-down features, catering to modern electronics demanding both precision timing and efficient power usage in small form factors.

Oscillators Replacement Considerations

Direct substitutes must match the 45.576 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other Mercury models in the same series if availability is an issue, ensuring all electrical parameters remain identical.
