Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range requirements against the official datasheet before procurement. Ensure that the 1.8V supply voltage aligns with the target system's power architecture. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications to ensure proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a 31.125 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint and the need for a power-down feature. Evaluate the 2.0x1.6 mm package size against available board space. Compare performance metrics such as phase noise and stability if available in the manufacturer documentation.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, which offers various frequencies within the same physical footprint. The series provides standard XO solutions with LVCMOS outputs and standby capabilities. Other variants in the series include different frequencies such as 8.3125 MHz, 50.000 MHz, and 96.768 MHz, sharing identical package and electrical characteristics.

Oscillators Replacement Considerations
