I have a question ADUM5240.
Do you have a IBIS models for ADUM5240.
(I can see that ADUM5200 IBIS models .)
If you have another simulation models ( S parameters ,SPICE models ),Could you sent?
HOD: I asked the designer and he said that we don't have an IBIS model specifically for the ADuM5240, but that you can use the IBIS model for the ADuM5200 as it uses equivalent circuits.
I have asked your question to the design engineer responsible for the ADuM5240, but there will be a delay in response because he is in China and they have a National holiday until next week. The ADuM5240 is older part, and we may not have an IBIS model, so I have also asked if the ADuM5200 IBIS model will do.
Thank you for your answer !
ADUM5200 will be considered as substitution.When a IBIS model was taken in, VIA, VIB, VOA and VOB could normally take it in.But VDD1, VISO, GND1 and GNDISO couldn't be taken in by an error.
If you know , please help .
What is the detailed information for the error?
I'll attach a picture of the error contents and a registered part.The one which could be imported, only at VIA, VIB, VOA and VOB.
VDD1, Viso, GND1 and GNDiso can't imported.
I have asked the designer to look at the error and then I will respond.
HOD: I asked the designer to look at your issue with using the ADuM5200 IBIS for the ADuM5420 and here is the response:
I go through the ibis model files. Most probably, this issue is caused by wrong port mapping, ADuM1200 is more similar with ADuM5240.
The port mapping information for ADuM5200 is attached.
The port mapping information for ADuM1200 is attached.
The customer could try the model of ADuM1200. If it doesn’t work, please let the customer to modify the port mapping information in ADuM5200.ibs, changes as below:
1 VDD power
2 VIA input1
3 VIB input2
4 GND GND
5 GNDiso GND
6 VOB driver
7 VOA driver
8 Viso power
