DS280DF810EVM: The question about the CTLE

Dear Sir.

I wonder if there is any way to turn the CTLE off, because I found that the minimal boost value of the CTEL is 6db @14Ghz.

there is what i do, but still didn' work.

1. I change to the adaptive mode 0 and disable the DFE, set the CTLE's boost value manually to 0.

2. Then i chose the pre-lock output to the raw data mode but  i found that the data isn't what i send into, it may be reconstructed by the CTEL.

Because i want to compare the data reconstructed by the CTEL with the original data i send into.

Any suggestion?

Thanks.
