Oscillators Procurement Notes

Verify the specific frequency tolerance and stability specifications against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system requirements. Ensure the 4-SMD package footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 31.08 MHz clock source is required with low voltage operation. Consider the LVCMOS output compatibility with downstream logic families. Evaluate the physical size constraints against the 2.0 x 1.6 mm package dimensions. Assess the need for power-down features if energy efficiency is a critical design parameter for the application.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystals and oscillators, offering various frequency options within the same package family. This specific model represents one of many available frequencies in the 18QHTF21 series, sharing common electrical and mechanical characteristics with other variants.

Oscillators Replacement Considerations
