Oscillators Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with design requirements. Confirm that the 1.8V supply voltage and LVCMOS output levels align with the target circuit specifications. Check for any required ordering suffixes or tape-and-reel packaging options if applicable to the production process.

Oscillators Selection Notes

Select this component when a precise 44.2368 MHz clock source is required for digital circuits. Ensure the design accommodates the 1.8V operating voltage and utilizes the standby feature if power efficiency is a priority. Verify that the 4-SMD no-lead package dimensions fit within the available board space constraints.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics 18QHTF21 series, which offers various frequency options in a small form factor. The series is designed for applications requiring stable clock signals with low power consumption. The 'PD' suffix typically indicates the inclusion of a power-down control pin for enhanced system energy management.

Oscillators Replacement Considerations

Direct replacements must match the 44.2368 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Consult the manufacturer's cross-reference list for verified substitutes. Ensure any alternative component supports the same standby functionality and meets identical electrical performance criteria.
