Procurement Notes

Verify the specific suffix '994' against official Renesas documentation to confirm factory pre-programmed configuration settings. Confirm current production status as some variants in this series may be subject to discontinuation notices. Ensure compatibility with the required VFQFN-56 package footprint during procurement planning.

Selection Notes

Select this component when eight independent outputs are required from a single reference source. Verify that the 40 MHz maximum input frequency aligns with the system's reference clock. Confirm that the 1 GHz output limit satisfies the target application's bandwidth requirements without necessitating higher-performance family members.

Part Context

This part belongs to the 8T49N281C series of Universal Frequency Translators. It utilizes FemtoClock technology to provide jitter attenuation and frequency synthesis capabilities. The device integrates alarm and monitoring functions suitable for robust communication network environments.

Replacement Considerations
