DS250DF810: CTLE Boost Value

Part Number: DS250DF810

Hi,

I would like to know the CTLE Boost Value (dB) of Programmer's Guide (specified in Table 46. CTLE Boost Table (subset of 255 Available Settings)) is estimated, calculated or measured.

What is difference between CTLE limit and non-limit? When and how to use it?

Thanks.

    Hi Jerry,
    This data is based on simulations.
    In non-limit mode the final stage of the equalization works like an analog buffer. On the other hand, when it is in limiting mode the final stage is digital or limiting - the output is either one or zero.
