The JTAG-HS3 programming cable is a high-speed programming/debugging solution for Xilinx FPGAs and SoCs. It is fully compatible will all Xilinx Tools, and can be seamlessly driven from iMPACT, ChipScope, EDK, and Vivado. The HS3 attaches to target boards using Xilinx’s 2x7, 2mm programming header.

The PC powers the JTAG-HS3 through the USB port and will recognize it as a Digilent programming cable when connected, even if the cable is not attached to the target board. The HS3 has a separate Vref pin to supply the JTAG signal buffers. The high speed 24mA three-state buffers allow the HS3 to drive target boards with signal voltages from 1.8V to 5V and bus speeds up to 30MBit/sec. To function correctly, the HS3’s Vref pin must be tied to the same voltage supply (VCCO_0) that drives the JTAG port on the FPGA.

The JTAG bus can be shared with other devices as the HS3 signals are held in high-impedance, except when actively driven during programming. The HS3 uses a standard Type-A to Micro-USB cable that attaches to the end of the module opposite the system board connector. The HS3 is small and light, allowing it to be held firmly in place by the system board connector.
