ON DIE TEMINATION RESISTOR VALUE SELECTION IN IBIS MODEL

Question asked by 9dc1212f-cb89-8a24-0100-014e727abccf on Jun 23, 2016

While selecting FPGA driver ibis model it either comes with a series or parallel termination, like sstl12_rtpio_g120c_r60_lv  and there are various variants of ODT resistors like

 

sstl12_rtpio_r40c_lv

sstl12_rtpio_r34c_lv

 

Can anyone help me is there any criteria for selection of particular series or parallel termination. How to select exact series or parallel ODT ibis model.
