David,
The full part number for the Altera device is 5AGZME1E3H29C4N. If you need firmware to help you with your design we can provide some examples, both Altera and Xilinx based. The main purpose of the TSW14J56 is to allow customers the capability to test our JESD204B EVM's. Many customers contact the FPGA vendors for support on how to interface to these ADC's and DAC's. We are currently working with both Altera and Xilinx on coming up with ways to help customers design these interfaces with app notes, sample firmware, ect... This is currently work in progress.
Regards,
Jim
