JTAG-HS3 Programming Cable for Xilinx FPGAs

The JTAG-HS3 Programming Cable from Digilent is a high-speed, all-in-one solution for programming and debugging Xilinx FPGAs and SoCs on compatible development boards. This compact cable delivers exceptional performance and seamless integration, making it an essential tool for embedded design engineers and developers.

Fully compatible with the entire suite of Xilinx development tools, the HS3 cable works effortlessly with iMPACT, ChipScope™, EDK, and Vivado™. It connects to target boards via the standard Xilinx 2x7, 2mm programming header, providing a direct and reliable link. The cable is powered entirely through its USB connection to your PC, which recognises it as a Digilent programming cable upon connection—even when not attached to a target board.

A key feature is its separate Vref pin, which supplies the JTAG signal buffers. This, combined with high-speed 24mA three-state buffers, allows the HS3 to drive target boards with signal voltages ranging from 1.8V to 5V and achieve bus speeds of up to 30Mbps. For correct operation, the cable's Vref pin must be connected to the same voltage supply (VCCO_0) that drives the JTAG port on the FPGA.
