I build the configuration of AD9545 by the ACE and dump the memory and apply *.txt in FBGA.
In our board,the OUT0A and OUT0B could generate 125MHz and 156.25MHz signal as we wish.
But there is no signal (30.72MHz) in OUT1A.
Could you help to check if the configuration is correct?
REF A=125 MHz
REF AA = 156.25 MHz
REF B = 30.72 MHz
REF BB = 1 Hz (from the GPS)
Please send me your cso file you obtained with ACE to check it.
There are multiple steps you have to make sure you take after you obtain a configuration file from ACE. Please make sure you follow them…
There are multiple steps you have to make sure you take after you obtain a configuration file from ACE. Please make sure you follow them. They are outlined in Initialization sequence section at page 160 in rev B data sheet.
Make also sure the driver of OUT1A (that is HCSL or CML) matches the hardware.
Make sure you generated a SYNC operation.
There may be other reasons, but I need to see the cso file first.
Sorry,I don't know what is the HCSL,but I attache the schematic of AD9545.
Yes,there is SYNC signal (30.72MHz)
Thanks a lot
In attachement,I upload the cso file in zip file and schematic of AD9545
