Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a precise 36.70016 MHz clock source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-profile, leadless surface-mount form factor suitable for space-constrained designs. Consider the 1.8V operating voltage as a primary constraint for power management integration. Evaluate the power-down feature if energy efficiency during idle states is a critical design requirement.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series offers various frequencies within a consistent 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down pin or functionality. This family targets applications needing reliable clock generation in compact consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 36.70016 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical specifications before swapping manufacturers.
