Oscillators Procurement Notes

Verify the specific frequency tolerance and stability requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no lead package dimensions fit the available PCB footprint. Check for any specific operating temperature range limitations required by the application environment to guarantee reliable performance.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable pin allows for dynamic power control in battery-operated devices. Consider the physical size constraints as the 4-SMD package is compact. Verify that the 38.86 MHz frequency meets the precise timing needs of the target digital logic or communication interface.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, focusing on standard frequency control products. The manufacturer specializes in quartz crystals and oscillators established since 1973. This specific model represents a surface-mount solution designed for modern electronic assemblies requiring precise clock signals in minimal space.

Oscillators Replacement Considerations

Direct substitutes must match the 38.86 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as load capacitance and drive level. Cross-reference with other manufacturers offering similar surface-mount oscillators if availability is an issue.
