Virtex-6 CXT - What is the Virtex-6 CXT device family?
The 11.2 ISE Design Suite shows a part selection for Virtex-6 CXT FPGA. What is this family and where can I obtain more information?
Virtex-6 CXT FPGAs provide designers needing cost-optimized 3.75 Gb/s transceiver performance an optimized ratio of built-in system-level blocks. These include 36 Kb block RAM/FIFOs, up to 15 Mb block RAM, up to 768 DSP48E1 slices, enhanced mixed-mode clock management blocks, advanced configuration options, Gen 1 PCI Express compatible integrated blocks, a tri-mode Ethernet media access controller (MACs), up to 241K logic cells, and strong IP support.
Customers needing higher logic or transceiver performance, more block RAM, additional DSP capability, Gen 2 PCI Express, additional Ethernet MACs, or over 241K logic cells should use the Virtex-6 LXT family instead.
If Spartan-6 LXT FPGAs capabilities are sufficient (speed, DSP count, block RAM size, logic count, transceivers), then Xilinx recommends the Spartan-6 family as the lower cost option.
