• Embedded devices utilizing standard crystal oscillator interfaces

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 PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 14.835546 MHz timing source is required for low-voltage applications. The integrated power-down feature makes it suitable for battery-operated or energy-efficient designs. Consider the small form factor if space constraints are critical within the target electronic assembly.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies with standardized LVCMOS outputs and low-profile packaging. The 'PD' suffix indicates the inclusion of a power-down control capability, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct replacements must match the 14.835546 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that substitute components support the same power-down functionality and meet equivalent electrical specifications for reliable integration.
