Honored ContributorHi Giovanni,
The Texas Instruments ADC12D1800RF is probably an old National Semiconductor part. There is a signal processing group at Berkeley that uses these ADCs on some of their Xilinx based hardware, eg., https://casper.berkeley.edu/ https://casper.berkeley.edu/wiki/hardware There may be performance test results on that site that will indicate what level of performance you can achieve with that ADC. Personally I have used the e2v parts (previously from Atmel), eg., see this page http://www.ovro.caltech.edu/~dwh/carma_board/ (http://www.ovro.caltech.edu/~dwh/carma_board/index.html) Given that you want to use a TR4 and the TI part is already in an FMC form-factor, you will need an FMC-to-HMSC adapter. They exist, but I have not tried using one. The Arria V kit comes with an FMC connector, so that might actually be a better choice; http://www.altera.com/products/devkits/altera/kit-arria-v-gx.html Regarding the speed of the LVDS links and how many are required, just read the data sheet. I suspect you'll find that the 3.6GSps samples are demultiplexed by 4, so the LVDS data rate is 3.6G/4 = 900Mbps, which is not too bad for LVDS. The link I provided above has a document (digitizer_tests.pdf) that show Stratix II LVDS tested at 1Gbps. Cheers, Dave
