The JTAG-HS2 is a high speed programming solution for Xilinx field programmable gate arrays (FPGAs). The cable is fully compatible with all Xilinx tools and can be seamlessly driven from iMPACT, Chip Scope, and EDK. The HS2 attaches to target boards using 6 pin, 100mil spaced programming header or Xilinx's 2x7, 2mm connector and the included adaptor. The PC powers the JTAG-HS2 through the USB port and will recognize it as a programming cable when connected to a PC, even if the cable is not attached to the target board. The HS2 has a separate Vdd pin to supply the JTAG signal buffers. The high speed 24mA three state buffers allow target boards to drive the HS2 with signal voltages from 1.8V to 5V and bus speeds of up to 30MBit/sec. To function correctly the HS2's Vdd pin must be tied to the same voltage supply that drives the JTAG port on the FPGA.
