Hi team,

Could you please give me the IBIS model of the I2C pins?

If it is not available, could you please share me the input pin capacitance of I2C pins(Typical and max)?

regards,

Hi Shinji,

Unfortunately, IBIS model is not available.

We have spec in datasheet for input capacitor. There is no spec for max and it should not affect the supply voltage drop due to higher ESR.

Best regards,

Hi Tanvee-san,

I understand that IBIS model is not available.

I would like to know the parasitic capacitance of the SCL(#13) and SDA(#12) pins which affect the signal integrity of the I2C bus.

It is normally modelled in IBIS, but if that is not available, could you please share me the design data?

regards,

Hi Shinji,

Thanks for details.

I will check capacitance value with design team and get back to you.

Thanks,

Tanvee

Hi Shinji,

Parasitic capacitance expected max around ~5pF. It should not exceed higher than this.

Best regards,

Tanvee
