Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply rail stability meets the oscillator's operational specifications to maintain signal integrity. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to avoid assembly issues.

Oscillators Selection Notes

Select this component when a stable 16.03495 MHz clock source is required for LVCMOS-compatible digital logic. The choice is driven by the need for low voltage operation and the ability to actively disable the oscillator to reduce power consumption during idle states. Consider the small form factor for space-constrained designs.

Oscillators Part Context

This part belongs to the QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's quartz industry. This specific model represents a standard XO variant within their portfolio, designed for general-purpose timing applications requiring reliable frequency generation.

Oscillators Replacement Considerations

Direct substitutes must match the 16.03495 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if availability is constrained.
