Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD No Lead package footprint matches the PCB layout to prevent assembly issues. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material declarations.

Oscillators Selection Notes

Select this component when a precise 16.044 MHz timing source is required within space-constrained designs. The choice is driven by the need for low-voltage compatibility at 1.8V and the integration of power-down capabilities. Consider the physical dimensions of the 2.0x1.6mm package to ensure adequate clearance on the printed circuit board. Evaluate the thermal performance and operating temperature range relative to the intended application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies tailored for modern digital applications. The 'PD' suffix indicates the inclusion of a power-down pin, enhancing system efficiency. These oscillators are designed to replace through-hole components in high-density electronics manufacturing processes.

Oscillators Replacement Considerations

Direct replacements must match the 16.044 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify that substitute parts support the same standby functionality and dimensional constraints. Check for equivalent electrical characteristics such as phase noise and jitter if specified in the original design requirements.
