Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance requirements against the official datasheet before procurement. Ensure compatibility with the target board's voltage levels and load capacitance specifications. Confirm that the 4-SMD package dimensions align with the PCB footprint design. Check for any specific handling instructions related to the no-lead package type during assembly.

Oscillators Selection Notes

Select this component when a precise 47.6 MHz reference is required for LVCMOS-compatible digital logic. Consider the 1.8V supply constraint and the availability of a standby feature for power-sensitive designs. Evaluate the thermal performance and operating temperature range against the application environment. Compare size constraints with other available packages if space is limited.

Oscillators Part Context

This part belongs to the series of surface-mount crystal oscillators produced by Mercury Electronics.
