Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your environment.

Oscillators Selection Notes

Select this component when a precise 14.74 MHz clock source is required for LVCMOS-compatible circuits. The choice is driven by the need for a low-profile surface-mount solution with active enable capabilities. Consider the 1.8V supply requirement as a primary constraint. Evaluate the package dimensions against available board space. This part is suitable for applications prioritizing size and power management over high-frequency performance.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized small outline package. The series provides options for different clock speeds while maintaining consistent electrical characteristics and form factors. This specific model represents one of the many frequency variants available in the lineup, sharing common pinouts and mechanical specifications with other members of the family.

Oscillators Replacement Considerations

Direct replacements must match the 14.74 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as jitter and phase noise if critical. Cross-reference with other manufacturers offering similar SMD oscillators only if they meet all specified technical requirements.
