- Communication equipment
Procurement Notes
Verify the specific frequency tolerance and stability requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations if used in extreme environments.
Selection Notes
Select this component when a small form factor XO is required for 1.8V logic systems. Consider the enable/disable feature if power efficiency is critical. Compare frequency stability specifications against other Mercury oscillators to ensure timing accuracy meets application needs. Verify compatibility with LVCMOS input thresholds of downstream components.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and package sizes. The 'OE' suffix typically denotes the presence of an output enable pin. This specific model provides a 10.244 MHz clock signal suitable for microcontrollers and data converters.
Replacement Considerations
Direct substitutes include other 10.244 MHz LVCMOS oscillators in 2.0x1.6mm packages from Mercury or compatible manufacturers. Ensure replacement parts match the 1.8V supply requirement and have identical pinout configurations for the enable function.
