RE: [IBIS-Users] How i use 100 ohm receiver resistence in my models

Model the inputs as a normal input buffer. Model the termination as a
series resistor between the two differential pins.

Subject: [IBIS-Users] How i use 100 ohm receiver resistence in my models

Hello Friends,

  I have LVDS RECEIVER cell in which a internal terminated 100ohm
resistence is present. How I will incorporate this resistence in my models.
    When I validate my DRIVER and RECEIVER independently then everythis
is fine but when I use a TX line between the driver and reciver the
swing is reduce in my SPICE due to this 100ohm resistence and my SPICE
and IBIS result become differ.

Regards
Akhilesh
