ALTGX Question

We are currently using the ALTGX module to transmit HD-SDI signal out on ARRIA II GX part. Using Quartus 9.1 every seems to work fine. However, this module does not have SD-SDI option available to transmit SD (270Mbps) video format. Is there anyway to get around the issue?

plus, what is the reason why SD-SDI option is missing from the module?

NOTE: There are only HD and 3G available from megaWizard !!

Thanks in advance,

JIMMY

    Have a look on the IP SDI.

    It's under interfaces and has what you're looking for.

    GXB are the physical transceiver and SD-SDI are serial that runs at only 270Mbit so they're "slow" for GXB.

    You can use a "normal" LVDS IO.

    Hope it helps.

    Best regards
