Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 3.3V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 4.897 MHz clock source is required with low-power standby functionality. The LVCMOS output is suitable for standard digital logic interfaces. Consider the 7.0x5.0 mm package size for space-constrained designs. Verify operating temperature range compliance if used in extreme environmental conditions.

Oscillators Part Context

This part belongs to the 3QHTF57 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 3.3V operation. The 'PD' suffix indicates the inclusion of a power-down pin or feature, allowing for active standby management in battery-powered or energy-efficient applications.

Oscillators Replacement Considerations

Direct substitutes include other 4.897 MHz LVCMOS oscillators in similar SMD packages from compatible manufacturers. Ensure equivalent supply voltage, output logic levels, and physical dimensions. Verify thermal and electrical performance characteristics match the original design requirements.
