Hi,

The current application scenario is that the 4xSGMII interface of PowerPC is connected to the low-speed 4port of the TLK10031. Our goal is to connect the SFP+ through the high-speed port of the TLK10031 and connect the 10G optical port to the outside. I don't know if I can achieve it, or what needs to be configured for TLK10031, please let me know. I appreciate it.

    Hi,

    Unfortunately, with further investigation this application TLK10031 will not work. When using SGMII there is no 8b/10b encoding of the data and the device will not be able to aggregate and serialize the data correctly. If you are able to use 8b/10b encoding then using TLK10022 or TLK10081 may be possible but furhter investigation will be needed.
