  • Page 7: On-Board Clock Capabilities

    On-Board Clock Capabilities (See Appendix B, Figure 19) The LatticeECP3 Versa Evaluation Board allows for several clock source options. Some of these options are con- trolled via the ispClock5406A programmable clock manager device. The ispClock5406A enables the reference clock from the PCI Express interface to provide a reference clock to the SERDES. This is true only when the board is in a PCI Express host socket.

  • Page 8: General Purpose Clock Source

    The PCI Express add-in card specification requires add-in boards to include capabilities to tell the host of its pres- ence. The LatticeECP3 Versa Evaluation Board allows this optional connection via a board jumper. The factory default will have two jumpers installed as shown below for the PRSNT connection to the PCI Express host.

  • Page 9: General Purpose Leds

    (See Appendix B, Figure 18) The LEDs provided on the LatticeECP3 Versa Evaluation Board are connected to general purpose FPGA I/Os. These LEDs provide status for user designs and must be included in the design. The LEDs illuminate when the FPGA output is driven LOW.
