Informazione prodotto "Digilent: JTAG SMT2 (210-251)"

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 3.3 V main power supply and a separate Vref supply to drive the JTAG signals. All JTAG signals use high speed, 24 mA, three-state buffers that allow signal voltages from 1.8 V to 5 V and bus speeds of up to 30 MBit/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 Figure 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. The SMT2 improves upon the SMT1 with the addition of three general purpose IO pins (GPIO0 GPIO2) and support for interfacing IEEE 1149.7-2009 JTAG targets in both 2 and 4-wire modes.
