Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm that the enable pin logic levels are compatible with the controlling microcontroller or FPGA to prevent unintended oscillator states during operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The 4-SMD package offers a small footprint compared to larger through-hole alternatives. Consider the enable feature if power management or clock gating is necessary within the system architecture to reduce standby current consumption.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in producing crystals, oscillators, and filters. This series represents their standard XO offerings designed for reliable performance in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 39.2 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution. Cross-reference with similar models like the 18QHTF21-37.200-OE or 18QHTF21-44.200-OE only if frequency adjustments are acceptable.
