Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and package configuration. Confirm that the required operating temperature range aligns with the system environment specifications. Check for any recent updates to the datasheet regarding pinout or electrical characteristics before finalizing the bill of materials.
Selection Notes
Select this component when a low-voltage 1.8V supply is available and LVCMOS signaling is required. The 4-SMD no-lead package offers a compact footprint compared to larger through-hole alternatives. Ensure the application does not require spread spectrum features, as this model is specified as a standard oscillator without modulation capabilities.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on surface mount quartz crystal oscillators. The series typically covers various frequencies and voltage levels, providing standardized timing solutions for consumer electronics and industrial equipment. The PD suffix indicates the inclusion of a power-down control feature.
