LSF0108: IBIS simulation question

Part Number: LSF0108
Other Parts Discussed in Thread: LSF0101

Hi team,
My customer is using LSF0108. And they're trying to simulate its signal integrity. Could you help me to check whether their simulation topology is correct?
Thank you!

Simulation model:

B_lsf_ss line_lsf1710 line_lsf1610_r

+ file='lsf0108_changed.ibs' model='LSF0101_IO_33_S'
+ typ=typ buffer=16 ss_state=on all_sm=1

Hi Luke,

I'm not entirely sure if the IBIS model will work without the bias voltage - when I have used it, I set it up with the full bias circuit as explained here: Understanding the Bias Circuit for the LSF Family

And I didn't have any problems. I can take a look on Monday and see if I can get it to work without the added bias circuit (perhaps there are presets in the file?)

I just tested this and found that you can use the device without the bias voltage, you just have to select the correct Vcc from the options (use the lowest value from your system).
