TCAN1043A-Q1: Resistance, inductance & capacitance of pin in IBIS model

Sri Viswa Sathiamoorthy

Part Number: TCAN1043A-Q1

Hi,

I need the pin resistance, capacitance & inductance of TCAN1043ADMTRQ1 from IBIS model but the data is missing in IBIS model.

Please provide the following data for CANH & CANL

1)pin resistance

2)pin capacitance

3)pin inductance

Thanks,

Sri Viswa

Hi Sri,

Sorry that we don't have pin resistance and pin inductance included in IBIS model, instead we use package parameters. But you can find input pin capacitance as C_comp for CANH and CANL. Please see figure below:

Please let me know if you need more information, or you can also refer to this app note.

Hi Sean,

Thanks for your reply

Actually, I need the CANH and CANL pin capacitance, inductance and resistance for simulation purpose. If i were to take the R_pkg, L_pkg and C_pkg to model the CANH and CANL separately, whether it is correct? (screenshot attached). I added 1Meg at the end to denote the tri-state of the CANH and CANL pin.

Thanks,

Sri Viswa

Hi Sri,

It looks correct. This is the way we use R_pkg, L_pkg and C_pkg in TI's IBIS model.
