Hi,

Please see my responses to your latest inquiries specific to the XCVR dynamic reconfiguration:

1. Re-configuring only the transmitter datapath data rate (Data rate division in TX). In this no .mif generation required. Right ?

[CP] Yes, you are right. YOu can perfor data rate division by controlling the rate_switch_ctrl[1:0].

2. Re-configuring the TX and RX CDR PLL across SATA data rates .mif genetation required. Right ?

[CP] Yes, you are right.

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

Best regards,

Chee Pin
