• Embedded system synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct configuration. Confirm that the required frequency tolerance and load capacitance specifications align with the target circuit design requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 46.1578 MHz reference is required in space-constrained designs. Ensure the host circuit supports 1.8V logic levels and can accommodate the physical footprint of the 2.0x1.6mm surface mount package for proper integration.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which specializes in quartz-based frequency control products. The brand has decades of experience in manufacturing crystals and oscillators, positioning this part within their standard line of surface-mount clock generators.

Oscillators Replacement Considerations

Direct substitutes must match the 46.1578 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify electrical parameters and pinout compatibility with alternative manufacturers before implementation.
