IBIS model of DS25BR440, DS38EP100 and DS32EV400

Greetings -

IBIS models convey the V-I and V-T data of the output and are mainly targeted at single-ended (e.g. LVCMOS) and also Differential (e.g. LVDS) that are two active states.  Devices that include additional levels or waveshapes such as transmit equalization (Pre-emphasis, De-Emphasis) and receive equalization are not supported by standard IBIS modeling. 

Usually this type signal condition features requieres a HSPICE modeling, and for certain equalizers this is supported.  There is also a new standard being developed called IBIS-AMI.  This calls DLL models to model the signal conditioning features and also other blocks such as CDR.  Only a few models are available for this currently and usually at the higher data rates (10G and above).

I will contact you direct with the HSPICE models that are available.
