Procurement Notes

Verify the specific suffix code matches your design requirements, as packaging or temperature grades may vary. Confirm that the operating voltage and signal levels align with your system architecture before ordering. Ensure compatibility with your existing clock tree topology to avoid integration issues during implementation.

Selection Notes

Choose this component when a combined buffering and multiplexing function reduces board space and complexity. Evaluate the maximum frequency requirement against the fifty megahertz limit to ensure adequate performance margins. Consider the number of required outputs to determine if additional devices are necessary for larger systems.

Part Context

This part belongs to Renesas' clock and timing product family, which focuses on precision signal generation and distribution. It complements other oscillators and buffers by providing active routing capabilities. The series targets applications where signal integrity and timing accuracy are critical for overall system performance.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar input-output ratios. Verify that any substitute maintains the required frequency range and electrical characteristics to ensure seamless integration without redesign.
