Oscillators Procurement Notes

Verify the specific operating temperature range and frequency stability parameters against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with the target system's power rails. Ensure the 4-SMD no lead package footprint matches the PCB design constraints to guarantee proper soldering and mechanical reliability during assembly.

Oscillators Selection Notes

Select this component when a precise 16.9048 MHz reference is required with low voltage operation. The LVCMOS output is compatible with standard digital logic families. Consider the standby feature if power efficiency is critical. Verify that the package size fits within the available board space and that the manufacturing tolerances meet the application's jitter and stability requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronic. The series typically offers various frequencies and voltage options. The -PD suffix likely indicates a specific pinout or packaging variant within the standard product line. These components are designed for high-reliability applications requiring stable frequency generation in small form factors.

Oscillators Replacement Considerations

Direct substitutes include other 16.9048 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify equivalent frequency stability and phase noise specifications. Check compatibility with existing PCB footprints and thermal requirements. Alternative brands may offer similar performance but require validation of electrical characteristics.
