Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for precise electrical tolerances to guarantee signal integrity in your application.

Oscillators Selection Notes

Select this component when a 40.985 MHz timing source is required with LVCMOS outputs. The 1.8V supply requirement dictates compatibility with low-voltage digital logic families. The enable pin allows for power management integration. Consider the small 2.0x1.6 mm package size for space-constrained designs. Verify thermal performance within the specified operating temperature range for reliable operation.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with standardized LVCMOS outputs and 1.8V operation. The 'OE' suffix typically denotes specific packaging or ordering options defined by the manufacturer. This family targets applications needing precise timing in compact form factors.

Oscillators Replacement Considerations

Direct substitutes must match the 40.985 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD 2.0x1.6 mm package. Verify pinout compatibility and enable function behavior. Check if alternative manufacturers offer equivalent specifications for the same footprint and electrical parameters.
