Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct frequency tolerance and temperature range specifications. Confirm that the required operating temperature range aligns with the component's rated limits before procurement. Cross-reference the package outline drawing to ensure mechanical compatibility with the target PCB footprint design.

Selection Notes

Select this component when a precise 61.25 MHz reference is required for low-voltage digital systems. The choice depends on the necessity for an LVCMOS interface compatible with standard logic families. Consider the physical size constraints of the 2.0x1.6 mm package during layout planning. Evaluate power consumption requirements relative to the available standby mode capabilities.
