Procurement Notes

Verify that the specific suffix OE matches the required enable/disable configuration and voltage specifications. Confirm the operating temperature range aligns with the target environment requirements. Ensure the 4-SMD no lead footprint corresponds to the PCB layout design. Cross-reference the frequency tolerance against system timing constraints before finalizing procurement orders.

Selection Notes

Select this component when a low-profile surface mount oscillator is required for 1.8V logic systems. Consider the ±50ppm stability specification for applications demanding moderate precision. Evaluate the 26mA current draw against available power budgets. Verify mechanical dimensions fit within the designated area on the circuit board assembly.

Part Context

This part belongs to the standard XO series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has extensive experience in producing crystals and oscillators since 1973. This specific model represents a surface mount solution designed for modern electronics manufacturing processes requiring small form factors.

Replacement Considerations

Direct substitutes include other 90.105 MHz LVCMOS oscillators in 4-SMD packages with compatible voltage levels. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers. Ensure replacement parts meet the same ±50ppm stability and temperature range specifications.
