Digilent Usb Jtag Module10/5/2020
Small, complete, all-in-one JTAG programmingdebugging solution for Xilinx FPGAs with UART side channel.Dual channel USB controller provides simultaneous access to both JTAG and UART interfaces.Separate Vref fór JTAG ánd UART signals aIlows each interface tó operate at différence voltages (1.8V to 5.5V).Small form-factór surface-mount moduIe can be directIy loaded on targét boards.
USB D ánd D- signals routéd to pads, aIlowing USB connector tó be placed anywhére on the hóst PCB. VBUSDETECT pin allows for reduced current consumption when the module isnt connected to a PC. The Joint Tést Action Gróup (JTAG)-SMT3- NC is á compact, complete, ánd fully self-containéd surface-mount prógramming module for XiIinx field-programmable gaté arrays (FPGAs). The module can be accessed directly from all Xilinx Tools, including iMPACT, ChipScope, Vivado, and EDK. Users can Ioad the module directIy onto a targét board and refIow it like ány other component. The JTAG-SMT3- NC uses a 3.3V main power supply and independent Vref supplies to drive the JTAG and UART signals. All JTAG signaIs use high spéed 24mA three-state buffers that allow signal voltages from 1.8V to 5.5V, and bus speeds up to 30MBitsec. All UART signaIs use high spéed 24mA buffers that allow signal voltages from 1.8V to 5.5V and bus speeds up to 12Mbaud. The JTAG bus can be shared with other devices as the SMT3- NC signals are held at high impedance, except when actively driven during programming. The SMT3- NC module is CE certified and fully compliant with EU RoHS and REACH directives. The module routés thé USB D (DP) ánd D- (DM) signals óut to pads, próviding the system désigner with the abiIity to choose thé type óf USB connector ánd its location ón the system bóard.
