• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the OE suffix with official documentation to confirm any specific ordering or testing variations.

Selection Notes

Select this component when a precise 76.746869 MHz clock source is required with low-voltage operation. Consider the LVCMOS output level for direct interfacing with compatible digital logic families. Evaluate the enable pin utility if power conservation during idle states is a design priority. Verify thermal performance within the specified operating temperature range for your application environment.

Part Context
