function and the accompanying SDI Audio IP cores.
The SDI MegaCore function implements a receiver, transmitter, or full-duplex SDI at
standard definition (SD), high definition (HD), or 3 gigabits per second (3G). The SDI
MegaCore function also supports dual standard (HD-SDI and SD-SDI) and triple
standard (SD-SDI, HD-SDI, and 3G-SDI). These modes provide automatic receiver
rate detection.
You can instantiate the SDI Audio IP cores with the SDI MegaCore function.
1 For more information about the SDI Audio cores, refer to “SDI Audio IP Cores” on
page 4–1.
