Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Consult the official datasheet for detailed electrical characteristics and reliability data.

Selection Notes

Select this oscillator when a precise 49.5733 MHz clock signal is required in space-constrained designs. The 1.8V operating voltage makes it suitable for battery-powered or low-power systems. The enable/disable feature allows for dynamic power management. Consider the small 2.0x1.6mm package size for high-density PCB layouts. Ensure the LVCMOS output level is compatible with the receiving logic inputs.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes a specific pinout or packaging variant. These components are designed for general-purpose timing applications. They compete with similar low-profile oscillators from other manufacturers.

Replacement Considerations

Direct replacements must match the 49.5733 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility for enable/disable functions. Cross-reference with other Mercury parts like 18QHTF21-49.5133-OE only if frequency differences are acceptable.
