DS100MB203: Channel loss and Equalization

DONGHO YU
Prodigy 175 points
Part Number: DS100MB203
Other Parts Discussed in Thread: DS125MB203

Hi all,

I'm wondering about Equalization of DS100MB203 and DS125MB203.

I have some issues related to Equalizer of DS100MB203 and DS125MB203.

I want to check relationship between our channel loss and your Equalizer.

What kind of equalizer is it in DS100MB203 and DS125MB203?

And can I get their transfer functions?

And 

I know that values in the EQ table of datasheet is not absolute values but increment amount from starting frequency.

Can I get absolute value table including ones at starting frequency?

Thank you.

    Hi Dongho,

    Both the DS100MB203 and DS125MB203 use a multi-stage continuous time linear equalizer (CTLE).

    I have a graphic of the transfer functions.  It is the same for the DS100 and DS125 variations.  Please email me at lee.sledjeski@ti.com so can can send you the graphic.

    The DS125MB203 uses a starting frequency of 200MHz as a baseline.

    The DS100MB203 starting frequency is < 200MHz since it is used with a maximum frequency of 10.3125 Gbps.

    Regards,

    Lee
