High-Speed I/O

Xilinx Virtex-II Pro FPGAs offer a variety of high-speed I/O solutions. The ML310 Embedded Development Platform’s high-speed I/O is based on the XC2VP30-FF896 FPGA’s RocketIO multi-gigabit transceivers (MGTs) and LVDS capability. The high-speed I/O signals on the FPGA are accessible through two personality module (PM) connectors, PM1 and PM2, on the ML310 board. The ML310 is the host board, functioning as the development platform for Virtex-II Pro FPGA. The PM connectors on the ML310 board provide a means for extending the functionality of the board through high-speed I/O pins. Personality modules connect to the ML310 board using Tyco Z-Dok+ docking connectors, PM1 and PM2. In addition to having differential pairs and shielding ground connections, Z-Dok+ connectors include utility connections for power, ground, and sensing. Tyco Z- Dok+ high-speed connectors are rated to 6.25 Gb/s.

Figure 2-19shows a personality module connected to the ML310 board through the PM1 and PM2 connectors. The plug, located on the ML310 board, is referred to as the host board connector; the receptacle, located on the personality module, is referred to as the adapter board connector.
