Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable pin configuration matches your board layout to ensure proper operational control during integration.

Oscillators Selection Notes

Select this model when a 49.09058 MHz clock signal is required in a compact form factor. Consider the 1.8V operating voltage for compatibility with low-power logic families. Evaluate the need for active enable/disable control versus always-on operation based on system power management strategies and timing requirements.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO series, which specializes in quartz-based frequency control solutions. The manufacturer has produced such components since 1973, focusing on precision timing devices including crystals, TCXOs, and VCXOs. This specific part represents their standard LVCMOS offering in a small outline package.

Oscillators Replacement Considerations

Direct substitutes include other 49.09058 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Abracon or SiTime, provided they match the 1.8V supply and pinout. Verify electrical parameters and mechanical dimensions before substitution.
