AMC1303M0510: Regarding spice model for AMC1303M0510

Part Number: AMC1303M0510

Dear TI team,

Good morning.

TI has provided IBIS file for AMC1303M0510,which can't be simulated in TI for Pspice.

So we request you to provide spice model for AMC1303M0510.

Expecting positive response.

Thank you,

Caliber

  • Thank you for the post!  We do not have SPICE (analog models) for digital output devices like the AMC1303M0510.  The IBIS (I/O Buffer Information Specification) model is all we can offer you at this time.

  • Hi Caliber,

    Can you let us know what it is that you are trying to do?  We do not have TI Spice or other analog models for the modulator devices.  You have the same query regarding the AMC1306 and neither devices supports an analog model platform,  If you can provide more details on what it is that you are trying to do, we might be able to provide you with some guidance in your project.

  • Dear Tom,

    Good morning.

    Thank you for your reply.

    We are trying simulate it .

    Is there any we can convert IBIS file to spice model.

    Thank you,

    Caliber

  • Hi Caliber,

    Unfortunately no, the IBIS model is basically a clocking/signal IO verification tool, there is no way to extract the modulator detail from that file.  The second issue is the filter module you would need to complete the simulation.  The output of the AMC1303 and AMC1306 is a bit-stream.  You would need to take that bit-stream and put it through a decimation filter in order to have any useful information.  Most people use a SINC filter with our modulators - you ha\\can get more detail on filter types here.  To that end, we do have a Excel calculator that can be used in conjunction with the AMC1303 or AMC1306 if you'd like to see the response of oversampling ratio versus SINC order.  That tool is located at this link.
