3. Functional Description

The SDI MegaCore function implements a receiver, transmitter, or full-duplex
interface. The SDI MegaCore function can handle SD, HD, and/or 3G SDIs.

The SDI MegaCore function consists of the following elements:

Protocol blocks

SDI receiver

SDI transmitter

A transceiver

A transceiver controller

In the MegaWizard Plug-In Manager, you can specify either protocol or transceiver
blocks or both for your design. For example, if you have multiple protocol blocks in a
design, you can multiplex them into one transceiver. The transceiver can be either a
soft-logic implementation or a GX transceiver.
