Hi,

As I understand it, you have some inquiries related to reconfiguring the CV XCVR between 1G and 2G. For your information, you can make use of the TX local divider and RX channel reconfiguration to switch between these two data rates since one is x2 of the other. I have shared with you a simulation example previously from wiki on CV dynamic reconfiguration between 800Mbps and 1600Mbps for your reference. This simulation uses embedded streamer to ease the rate change.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin
