Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 48.002 MHz clock source is required with low power consumption capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if power management during idle states is critical for the application. Verify that the operating temperature range meets the environmental conditions of the final product deployment.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO series, which provides standard frequency solutions. The company has a history of manufacturing quartz crystals and oscillators. This specific model represents a surface-mount option for applications requiring reliable timing signals without the need for differential outputs or spread spectrum modulation features found in other series.

Oscillators Replacement Considerations

Direct replacements must match the 48.002 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as jitter and phase noise before substituting.
