SDI Audio Extract MegaCore Function
SDI Audio Extract MegaCore Function
The SDI Audio Extract MegaCore function accepts the SD-, HD-, and 3G-SDI from the
SDI MegaCore and extracts one channel pair of embedded audio.
The format of the embedded audio is in accordance with the SMPTE272M-A standard
for the SD-SDI video standard, or in accordance with the SMPTE299M standard for
HD-SDI and provisionally for 3G-SDI video standard. If you are extracting more than
one channel pair, you must use multiple instances of the component. This MegaCore
function supports AES audio format for 48-kHz sampling rate.

Audio Extract or Audio Extract with Avalon
The SDI Audio Extract MegaCore function consists of the audio extraction core and a
register interface block that provides support for an Avalon-MM control bus.
The clock recovery block recreates a 64 × sample rate clock, which you can use to clock
the audio output logic. As the component recreates this clock from a 200-MHz
reference clock, the created clock may have a higher jitter than is desirable.
