Procurement Notes
Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm the exact enable/disable configuration and packaging variant. Ensure the 1.8V supply requirement aligns with system design constraints. Cross-reference the 10.43 MHz frequency specification with application requirements to avoid timing mismatches. Confirm the 4-SMD package footprint matches PCB layout specifications before procurement.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside LVCMOS interface compatibility. The enable/disable feature allows for power management in battery-operated devices. The small 2.0x1.6 mm footprint is suitable for space-constrained designs. Consider the operating temperature range and load capacitance requirements relative to the target application environment.
Part Context
This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The OE suffix typically denotes specific packaging or enable features within the product line. Mercury Electronics specializes in frequency control products including crystals and oscillators.
Replacement Considerations
Direct substitutes include other 10.43 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as jitter and phase noise. Check if alternative manufacturers offer equivalent enable/disable functionality and package dimensions.
