Hi,
I have the AD9545 evaluation board configured through ACE, and working. It outputs what I need as long as the PC stays connected.
It receives 49.152 mhz and outputs 10 mhz
I want it to boot with the same configuration on its own, with no PC attached. What's the simplest way to do this?
Thanks.
HI,
for example, you can use your own controller to configure the AD9545. Here is what you need to do:
From ACE, save the register configuration by clicking on Save Registers button in the down left corner of the GUI.
Then connect a controller to the SPI port of the AD9545 as described in the attached paper.PDF
Follow the initialization procedure given in the rev C data sheet at page 164.
There is an EEPROM on the evaluation board (U601) that was put there so AD9545 can upload its own configuration into it. Then, after power up, the AD9545 could download its configuration from that EEPROM. But the ACE plugin does not have that feature. If you'll ever design your own board with a controller and the AD9545, you could follow the procedure in the application note AN-2072 (follow the link below) to upload the configuration into the EEPROM.
