Greg,
What you call “IBIS file” should be “IBIS [Model]”. PKG can be in the “IBIS
file”, but for SerDes modeling is almost always replace with a “Broadband
ISS” model. The expectation is that IBIS 5.2 will include “Broadband ISS”
models.
In the Rx Jitter Model, I assume EQ1 is a CTLE (Peaking Filter), and EQ2 is
DFE. I believe that CDR should be included in the “algorithmic model”. It is
not clear to me if the CDR input should be after EQ2, or between EQ1 and
EQ2.
In slide 1, I have proposed adding Rx_Sj_Frequency, and
Rx_Clock_Recovery_Sj_Frequency. The ATM committee has requested that
Rx_Noise_Pad and Rx_External_Reference has been removed from BIRD123 –
although I would like to confirm this with the committee.

David,
Here's my latest drawing. I would like to talk about RX jitter next time.

Hi all,
Was there an update to Greg’s jitter model drawing, more recent than what
Arpad sent to the reflector on Tues. at 12:30 pm PDT?
Thanks,
