- Integrated enable/disable pin for power control
- Compact 4-SMD no-lead surface mount package
Applications
- General clock signal generation
- Digital system timing references
- Embedded controller circuits
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside precise timing needs. The LVCMOS output ensures direct interfacing with standard digital logic without additional level shifting. Consider the enable feature if dynamic power saving is necessary for battery-operated or energy-efficient designs requiring periodic oscillator shutdown.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal oscillators. The manufacturer has decades of experience in frequency control products, including crystals, TCXOs, and VCTCXOs. This series represents their standard XO offerings designed for reliable performance in consumer and industrial electronics applications.
Replacement Considerations
Direct substitutes include other 10.209 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution. Cross-reference with similar models like the 18QHTF21-44.200-OE only if frequency differences are acceptable.
