Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before procurement. Ensure the 1.8V supply rail stability meets the oscillator specifications. Confirm that the 4-SMD no-lead package dimensions align with the PCB footprint design to ensure proper soldering and mechanical reliability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 32.256 MHz frequency. The LVCMOS interface ensures compatibility with general-purpose digital logic families. Consider the standby feature if power efficiency is critical. Verify that the operating temperature range provided in the official datasheet covers the intended environmental conditions of the final product deployment.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in producing crystals and oscillators. This specific part represents a standard fixed-frequency solution within their portfolio, designed for reliable performance in consumer and industrial electronics requiring precise timekeeping.

Oscillators Replacement Considerations

Direct replacements must match the 32.256 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference pinouts and electrical characteristics carefully. Alternative models from other manufacturers require verification of thermal and electrical compatibility.
