Procurement Notes
Verify the exact part number against official Mercury Electronics documentation to ensure compatibility with your specific design requirements. Confirm that the 1.8V supply voltage and LVCMOS output levels match your target circuit's electrical specifications. Check for any specific ordering suffixes or package variations that may affect mechanical integration or performance characteristics in your application.
Selection Notes
Select this component when a stable 83.31 MHz clock signal is required with low voltage operation. Ensure the host system supports LVCMOS logic levels and can provide a regulated 1.8V power rail. Consider the enable/disable feature if power efficiency during idle states is a priority for the overall system design.
Part Context
