Overview

The Joint Test Action Group (JTAG)-SMT2 is a compact, complete and fully self-contained surface-mount

programming module for Xilinx field-programmable gate arrays (FPGAs). The module can be accessed directly from

all Xilinx Tools, including iMPACT, Chipscope™, and EDK. Users can load the module directly onto a target board

and reflow it like any other component.

The JTAG-SMT2 uses a 3.3V main power supply and a separate Vref supply to drive the JTAG signals. All JTAG

signals use high speed, 24mA, three-state buffers that allow signal voltages from 1.8V to 5V and bus speeds of up

to 30MBit/sec. The JTAG bus can be shared with other devices as systems hold JTAG signals at high-impedance,

except when actively driven during programming. The SMT2 module is CE certified and fully compliant with EU

RoHS and REACH directives. The module uses a standard Type-A to Micro-USB cable available for purchase from

Digilent, Inc.

Users can connect JTAG signals directly to the corresponding FPGA signals, as shown in Fig. 1. For best results,

mount the module adjacent to the edge of the host PCB over a ground plane. Although users may run signal traces

on top of the host PCB beneath the SMT2, Digilent recommends keeping the area immediately beneath the SMT2

clear.

Note: Keep the impedance between the SMT2 and FPGA below 100 Ohms to operate the JTAG at maximum speed.
