• Integrated enable and disable control functionality
• Compact 4-SMD no-lead surface mount packaging

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly issues.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable pin allows for dynamic power control, making it suitable for battery-operated devices. Consider the operating temperature range specified in the documentation to ensure reliability under environmental conditions.
