Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge protection during installation.

Oscillators Selection Notes

Select this oscillator when a stable 16.333 MHz reference is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage as a primary constraint for power supply design. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Evaluate the physical dimensions of the 4-SMD package against available board space.

Oscillators Part Context

This component belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small form factor. The 'PD' suffix indicates the inclusion of a power-down control pin or functionality. These oscillators are part of Mercury's broader portfolio of quartz-based frequency control products, which includes crystals, TCXOs, and VCXOs.

Oscillators Replacement Considerations

Direct replacements must match the 16.333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility if substituting with different manufacturers. Ensure equivalent electrical characteristics such as phase noise and stability are met for the specific application.
