Figure 13.  Agilex™ 3 and Agilex™ 5 DisplayPort SST RX-only
  • To generate this RX-only variant, in the GUI, on the IP tab:
    • Turn on Support DisplayPort sink (RX_SUPPORT_DP).
    • Turn off Support DisplayPort source (TX_SUPPORT_DP).
  • The IOPLL drives video clock at a fixed frequency (in this case, 300 MHz by default).
  • The DisplayPort sink receives video from an external video source such as a GPU and decodes it for the parallel video interface.
