Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for any specific handling instructions regarding the no-lead package during assembly processes to maintain component integrity.

Oscillators Selection Notes

Select this component when a 41.2081 MHz clock source is required for LVCMOS-compatible digital logic. The choice is driven by the need for a low-profile 2.0x1.6mm SMD package and integrated power management features. Consider the 1.8V supply requirement and ensure the application supports the standby functionality. Validate thermal performance within the specified operating temperature range for the intended environment.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount oscillators. The series offers various frequencies with standardized LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down feature.
