Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct output logic and package type. Confirm that the PD suffix aligns with the required standby functionality. Cross-reference the frequency tolerance and operating temperature range with system requirements before procurement to avoid integration issues.

Selection Notes

Select this component when a 1.8V supply voltage is mandated by the system architecture. Ensure the PCB layout accommodates the 2.0x1.6mm footprint. Verify that the LVCMOS output swing matches the input thresholds of the connected load. Consider the standby feature if power efficiency is a critical design constraint.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series typically offers various frequencies within a small form factor.
