Oscillators 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 no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly and long-term performance stability.

Oscillators Selection Notes

Select this component when a precise 14.152343 MHz clock source is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage as a primary constraint for compatibility with modern low-power processors. Evaluate the need for a standby feature if power efficiency during idle states is critical. Compare the physical dimensions against available board space to ensure the 2.0x1.6 mm package fits within the designated area without interfering with adjacent components.

Oscillators Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar small form factors. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from continuous-operation variants. Mercury Electronics is a specialized manufacturer of frequency control products, leveraging decades of experience in quartz crystal technology to provide stable timing solutions for electronic industries.

Oscillators Replacement Considerations

Direct substitutes must match the 14.152343 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Cross-reference with other manufacturers offering identical form-factor oscillators to ensure functional equivalence in the target application.
