Extended FPGA Options
Figure 2-22 shows the Extended FPGA Options page.
• Digitally Controlled Impedance (DCI) – When selected, this option internally
terminates the signals from the QDR II+ SRAM read path. DCI is available in the High
Performance Banks.
• Internal Termination for High Range Banks – The internal termination option can be
set to 40, 50, or 60Ω or disabled. This termination is for the read datapath from the
QDR II+ SRAM. This selection is only for High Range banks.
