Overview

The Digilent JTAG-HS3 is a high-speed programming and debugging solution designed specifically for Xilinx FPGAs and SoCs. It connects a PC to a target board via a standard USB cable and a 14-pin JTAG header, supporting target voltages from 1.65V to 6V.

Why Choose This Part

The JTAG-HS3 features a high-speed USB 2.0 interface capable of driving JTAG signals at up to 30 Mbps while maintaining compatibility with Xilinx Vivado and ISE. Its robust power design supports a wide I/O voltage range and provides up to 50mA of current sourcing/sinking capability for flexible integration with various logic levels.

Applications

Xilinx SoC Debugging
Utilizes the dedicated open-drain buffer on pin 14 to allow Xilinx software to reset the processor core of Zynq platforms.
High-Speed FPGA Configuration
Provides a high-bandwidth JTAG interface for rapid bitstream loading during development and production testing.
In-System Programming
Enables direct programming of on-board SPI or BPI flash memory through the JTAG interface for permanent firmware storage.

Getting Started

Connect the module to a host PC using a micro-USB cable and attach the 14-pin female header to your target board. It is natively supported by the Xilinx Vivado Design Suite and the Digilent Adept Toolset, requiring no additional driver installation on most modern operating systems.

Also Consider

JTAG-HS2 Programming Cable DGLDigilent, Inc. - A similar high-speed JTAG solution that uses a 6-pin interface instead of the 14-pin Xilinx-specific header.
