The Mictor connector single line model can be downloaded directly from the AMP web site. The closest available model is entitled MICTOR, .025" PITCH, 2 ROW, VERTICAL PLUG TO VERTICAL RECEPTACLE, 0.260" [6.6mm] HEIGHT .

The connector assembly (plug and receptacle together) can be viewed as a transmission line with an impedance of 45Ω and a propagation delay of 39ps. For more accurate modeling, multi-line models can be requested from AMP.

All traces are microstrips (on outer layers over ground planes).

All traces are designed to a target impedance of 50Ω ± 2Ω.

Trace lengths from Mictor to input buffers are 0.329 inches maximum and 0.193 inches minimum.

Average trace separation is 0.010 inches.

Er = 4.5.

The probe input buffers are a mixture of Fairchild FIN1104MTD and FIN1108MTD devices (4 channel & 8 channel devices respectively).

The datasheets, ibis and hspice models for these devices are available on the Fairchild web site.
