Hi, I have to establish a 50MHz serial communication with a Spartan3, so:
1) should I place termination resistors on data_in, data_out or clock pins? Value? 2) could I use somehow DCIs (I'm working with LVCMOS33 standard)? then on the pull-up/down: 3) which JTAG pins should I pull-up? With 10KOhms? 4) I'll need to use serial mode (slave or master) also on the configuration stage, so I could harware fix the mode pins as I'll always be able to connect with the JTAG, no matter how the pins mode are set, right? Thanks, Marco- posted
