| - | The Sword board includes several oscillators and crystals, of which one is connected to the FPGA. One differential LVDS 200MHz oscillator is connected to MRCC GPIO pins AD12/AD11 in bank 33. The clock can drive MMCMs or PLLs to generate clocks of various frequencies and with known phase relationships that may be needed throughout a design. Some rules restrict which MMCMs and PLLs may be driven by the 200MHz input clock. For a full description of these rules and of the capabilities of the Kintex-7 clocking resources, refer to the “7 Series FPGAs Clocking Resources User Guide” ([[http://www.xilinx.com/ | + | The Sword board includes several oscillators and crystals, of which one is connected to the FPGA.

| Xilinx offers the Clocking Wizard IP core to help users generate the different clocks required for a specific design. This wizard will properly instantiate the needed MMCMs and PLLs based on the desired frequencies and phase relationships specified by the user. The wizard will then output an easy-to-use wrapper component around these clocking resources that can be inserted into the user’s design. The clocking wizard can be accessed from within the Vivado and IP Integrator tools. | Xilinx offers the Clocking Wizard IP core to help users generate the different clocks required for a specific design.

| The pins on the shield connector typically used for I2C signals are labeled as SCL and SDA. When using these signals to implement an I2C bus it is necessary to attach a pull-up resistor to them. On the Sword, this can be done by placing two shorting blocks horizontally across the J4 header. | The pins on the shield connector typically used for I2C signals are labeled as SCL and SDA.
