Hi,

 

I assembled the device with CY68013 that is based on schem (http://www.analog.com/media/en/technical-documentation/evaluation-documentation/AD9548_schematic.pdf) of the PCBZ9548 and flashed the EEPROM with original code that is accepted by this software http://www.analog.com/media/en/evaluation-boards-kits/evaluation-software/AD9547_AD9548_USB%20EEPROM.zip. After that I installed the http://www.analog.com/media/en/evaluation-boards-kits/evaluation-software/AD9547_AD9548_Evaluation_Installation.zip  and driver from these location: C:\Program Files\Analog Devices\USB Drivers\LRF. Next I connected AD9548 that is mounted on my board with CY68013 over I2C only without Reset and IRQ signals. Everything is fine because I can calibrate the AD9548, set DDS frequency, look at the status but the software identifies AD9548 like AD9547 (the green legend in bottom near STATUS and IRQ). So I see only two outputs and can not load stp file because this one was saved for AD9548 but software thinks that I work with AD9547. Are there special features probably hardware or software that I did not take into account?

 

Sincerely, Dmitriy
