SDI II Intel® FPGA IP Core

SDI IP Diagram in V Series
12G SDI Diagram in 10 Series

The serial digital interface (SDI) II intellectual property (IP) core implements a transmitter, receiver or full-duplex SDI at standard definition, high definition or 3G to 12G rate as defined by the Society of Motion Picture and Television Engineers. The SDI II IP core supports multiple standards. These modes provide automatic receiver rate detection and transceiver dynamic reconfiguration.

The SDI II IP core highlights the following new features:

  • IEEE encryption for functional simulation across a variety of tools
  • Dynamic generation of user simulation testbench that matches the IP configuration
  • Dynamic generation of design example that serves as common entity for simulation and hardware verification
