Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable and within the specified operating range. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to ensure proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a low-profile, low-power oscillator is required for 28.63636 MHz applications. Consider the LVCMOS output compatibility with your target logic family. Evaluate the thermal performance and environmental conditions to ensure the operating temperature range meets system specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages, designed for space-constrained applications. The PD suffix indicates the inclusion of a power-down pin for enhanced energy management in portable or battery-operated devices.

Oscillators Replacement Considerations

Direct substitutes must match the 28.63636 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as jitter and phase noise before substitution.
