The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power management
• Surface-mount 4-SMD no lead package design

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable pin feature supports dynamic power saving strategies in battery-operated devices. Consider the 4-SMD form factor for space-constrained layouts where through-hole mounting is not feasible. Validate thermal performance within the specified operating temperature range for the intended environment.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The manufacturer has decades of experience in quartz crystal production. This specific model represents a surface-mount solution offering stable frequency generation for modern electronic systems requiring reliable timing references with minimal board space consumption.

Replacement Considerations

Direct substitutes must match the 58.8375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Cross-reference with other Mercury Electronics models or industry-standard equivalents ensuring identical functional parameters and physical dimensions for seamless integration.
