We would like to use the AD9957 eval board to generate TDMA digital RF traffic. Is there a way to configure the board to periodically generate bursts (i.e. retransmit the data stored in the FIFO), either under control of an internal timer or an external pulse source? I realise that I can add some external logic to tristate the CPLD and then generate suitable TX_ENABLE and RTb signals; but since TDMA modulation is such a common use case for the AD9957, I'd hoped that there would be some support for it built in to the eval board.
Failing that, is the source code for the CPLD available? A minor modification to the CPLD logic is certainly all that's required for my application.
