Hi,

I have a few questions about the FMCOMMS1 hardware initialisation sequence for the transmit path:

 

http://wiki.analog.com/_media/resources/fpga/xilinx/fmc/ad-fmcomms1-ebz/xcomm_block.png?w=600

 

Q01: In the above diagram, are all the devices (AD9122, AD9643, AD9548, AD9523-1 and ADL5380) controlled by a single SPI controller on the SPI bus, connected to the FMC card?

 

Q02: What is the sequence for configuring the transmit path?

 

Q03: What is the sequence for configuring the receive path?

 

Regards,

 

Elvis Dowson
