Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. 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. Validate the enable pin logic polarity with your microcontroller or FPGA outputs to ensure correct operation.

Selection Notes

Select this component when a 93.3 MHz clock source is required with LVCMOS signaling. Consider the 1.8V operating voltage for compatibility with modern low-power logic families. The small 2.0x1.6 mm package is ideal for space-constrained designs. Evaluate the need for an enable pin to manage power consumption during idle states. Compare performance metrics such as phase noise and stability against alternative oscillators if high precision is critical.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series is designed for applications needing reliable timing solutions in a minimal footprint. Mercury Electronics has a long history in quartz crystal manufacturing, providing industry-standard frequency control products. This specific model continues the tradition of compact, high-reliability oscillators for electronic systems.

Replacement Considerations

Direct substitutes include other 93.3 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6 mm package from compatible manufacturers. Verify electrical parameters such as supply voltage, output swing, and enable logic before substitution. Ensure mechanical dimensions and pinout configurations are identical to avoid PCB redesign. Check datasheets for equivalent performance specifications regarding jitter and temperature stability.
