• Embedded systems with low-power constraints

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 4-SMD no-lead footprint matches your PCB layout specifications. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly and long-term performance stability.

Selection Notes

Select this component when a stable 100.0023 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage as a primary constraint for power supply design. Evaluate the physical dimensions of the 4-SMD package against available board space. Compare enable/disable features against power management strategies if dynamic clock gating is necessary for the application.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These components are designed for general-purpose clock generation in consumer electronics and industrial control systems where size and power efficiency are critical factors for integration.

Replacement Considerations

Direct substitutes include other 100.0023 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substitution. Alternative frequencies like 100.0025 MHz may require firmware adjustments.
