Hi,

Can you tell me how to program 2 CDCE949 on the same I2C bus with the clock pro software?

Thanks,

Norman

    Hello Norman,
    The devices have re-programmable LSBs of the slave address. You can save this setting in the EEPROM and you solve the collision on the bus.
    You have several options like using an I2C multiplexer or an I2C buffer to gate the signals.
    When the units are already assembled and you are trying to solve an in-system conflict: When you have the option you can try to individually power the devices.

    Best regards,
    Patrick
