B2B Connector Pinout (VI Tracker T120 Board and VITUD FT2232H Board)

• Need to connect main VI Tracker FPGA Board (T120) and VITUD Usb debugger Board (FT2232H) with:

  • CDI1
  • CDI0
  • CCK
  • SS
  • CONDONE
  • CRESET_N
  • TCK
  • TDI
  • TDO
  • TMS
  • 5V?
  • GND
  • etc

  

Crystal:

Channel A - MPSSE (JTAG, SPI, I²C), UART, FIFO

Channel B - MPSSE, UART, FIFO, Bit-bang

NEED BOTH JTAG AND SPI

JTAG Channel A used for flashing

SPI Channel B is used for communication with the FPGA after it has run (logging, command interface,telemetry)

VPLL/VCORE LC Filter

• Need to be high impedence during USB transceiver harmonics (100–500 MHz.)
• Low DC Resistance
• High impedence in 100-500MHZ range
