• Standby (Power Down) capability
• Surface mount construction

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications. Confirm that the 1.8V supply voltage aligns with the host system's power rails. Ensure the 4-SMD package footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 14.395 MHz clock source is required for low-voltage digital logic. The LVCMOS output ensures compatibility with standard CMOS inputs. Consider the standby feature if power efficiency is critical. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies tailored for consumer electronics and industrial applications. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct replacements must match the 14.395 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Cross-reference with other manufacturers offering identical electrical characteristics and pinout configurations to ensure functional interchangeability without redesigning the host circuit.
