SPICE model of ADG2188

Hi Saril,

Unfortunately we do not have a spice model for this device at the moment. 

On the other hand, we have available EVAL-ADG2188 which you can use to evaluate the part.

Hi May, Thanks for your reply. Somehow I did not have any notification and was not able to check it back. I did test using another board which we use the same xbar and passed the signal I am interested of. it looks promising.

is there a chance we can get a encrypted HPSICE model?

Also could you please tell me the propagation delay from x to y if the connection is always made ON. I could not find this information on the datasheet. Only TON and TOFF are provided.

Hi Saril,

Apologies, an HSPICE model is also not available.

With regards to the propagation delay of x to y question, it should be same as Ton/Toff as this is measured after the 3-byte write (8-bit device address & two 8-data bits). Kindly see page 20 of the ADG2188 datasheet.

Any changes to x and y channels will be read after all address and data bits are written.

Let me know if this helps.

Best Regards,

May

Hi May, I am curious after we set the connection X to Y on reset of the unit we will not change this set up as long as the unit is powered on. Meaning once the connection is established we will not make the change through I2C transaction. In this scenario what would be the propagation delay for a signal to travel from X pin to Y pin or vice versa.

Hi Saril,

It should be less than ton/toff.

Thanks Maya. Do you have a rough estimate on how much the pd will be?

Thanks,

Saril
