SDI MegaCore Function
from Altera Corporation
Features and Description
The Altera® SDI MegaCore® function implements a receiver, transmitter, or full-duplex serial digital interface (SDI) at standard definition (SD), high definition (HD), or 3-gigabits per second (Gbps). The SDI MegaCore function also supports dual or triple-rate standards, which provide automatic receiver rate detection.
The Society of Motion Picture and Television Engineers (SMPTE) defined an SDI that video system designers widely use as an interconnect between equipment in video production facilities.
The SDI MegaCore function supports the following SDI data rates:
- 270-Mbps SD SDI, as defined by SMPTE259M-1997 10-Bit 4:2:2 Component Serial Digital Interface 1.485/1.4835 Gbps
- HD SDI, as defined by SMPTE292M-1998 Bit-Serial Digital Interface for High-Definition Television Systems
- SDI 3 Gbps, as defined by SMPTE425M-2006 3 Gb/s Signal/Data Serial Interface–Source Image Format Mapping
- Full support for dual-link SDI, as defined by SMPTE372M-Dual Link 1.5 Gbps Digital Interface for 1920 x 1080 and 2048 x 1080 Picture Formats
- Dual standard that switches between 270 Mbps and 1.485 Gbps
- Triple-rate SDI that switches between 270 Mbps, 1.485 Gbps, and 2.97 Gbps
Other SDI features include:
- Support for multiple SDI standards (see Table 1)
- Transmitter includes:
- Cyclical redundancy check (CRC) encoding (HD only)
- Line number (LN) insertion (HD only)
- Word scrambling
- Receiver includes:
- CRC decoding (HD only)
- LN extraction (HD only)
- Framing and extraction of video timing signals
- Word alignment and descrambling
- IP Toolbench interface
- Intellectual property (IP) functional simulation models for use in VHDL and Verilog HDL simulators supported by Altera
- Support for OpenCore Plus evaluation
Table 1 shows the SDI standard support for various devices.
