AFE7769: Channel Latency

Adrian Liu

Part Number: AFE7769

Hi Team,

              As the title, what's the total link latency of TX/FB/RX channel ? What's the full rate in the follow excel?

             

             Does the latency change with different interface data rate and LMFS parameters ?  How about Tx data rate = 491.51MHz and Rx data rate = 245.76MHz?

BR

    Hi Adrian

    we will have to ask the design team for guidance on the overall latency. Please advise the exact LMFS setting so the team can simulate the latency. Is this the same as the latest use case shared on Webex team? Please send out the exact requirement of JESD204C LMFS mode and also the lane rate so we can follow up on this.

    Hi Adrian,

    Please also advise their exact bandwidth/DDC/DUC setting. We may need to gather the latency of the DDC/DUC path as well for you to complete the latency calculation.
