UCD9090A: Pulse generation

Part Number: UCD9090A

Hi team,

Is there a way to generate a pulse on a LGPO without using the system reset function?

In fact, my customer would like to generate two different reset signals.

Thanks in advance for your feedback.

    Hi Pol

    Yes, it is possible. what're the condtions to generate a pulse on LGPO, rail status or GPI status?

    Basically, you need to have define 3 LGPO, the first GPO is to follow the events, the 2nd GPO is to follow the events as the firs LGPO but with some extra delay(this is the pulse width), the third LGPO is to XOR the first two LGPO together which will be a pulse.

    Hi Yihe,

    Thanks for your feedback.
    If I understand correctly your reply, it's not possible to generate a pulse with only one GPO?
    Regards,

    Hi Pol
    For the first 2 GPO, they can be defined as virtual GPO, which means that they can be without any phyiscal pins.

    If you can let me know the conditons for the pulse, i can see what to do.

    Regards
