Oscillators Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout to avoid soldering issues during assembly.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside precise timing needs. Consider the small 2.0x1.6 mm package size if board space is limited. The enable/disable feature makes it suitable for battery-powered applications requiring power conservation during idle states.
Oscillators 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, positioning this model as a standard solution for reliable clock signals in consumer and industrial electronics.
Oscillators Replacement Considerations
Direct substitutes include other 20.025 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as phase noise and stability before swapping.
