SDI-ASI Combo - Auto Detect Reference Design for Stratix IV GX Devices
This reference design demonstrates the SDI-ASI auto protocol detector based on the combination of the current Altera SDI and ASI MegaCore® functions,and shows how to demonstrate the SDI-ASI combo block with the Stratix® IV GX
Stratix IV GX audio video development board.
The SDI-ASI_combo TX is able to transmit SD, HD, 3G and ASI video signal.
The SDI-ASI_combo RX is able to receive SD, HD, 3G and ASI video signal.
Software requirement: Quartus II 12.0 sp1 or later Quartus Version with using the SDI lib attached in this project.
Hardware Requirement : Stratix IV GX FPGA development board and SDI HSMC
Triple-Standard SDI in PMA DIRECT Mode Reference Design for Stratix IV GX Devices.
The reference design demonstrates how SDI can be implemented in PMA DIRECT Mode, which able to be fit at regular transceiver channel and CMU channel. There are total of 6 SDI in PMA DIRECT Mode successfully fit in this reference design.
Software requirement : Quartus II 10.0 sp1 or later Quartus Version with using the SDI lib attached in this project.
Hardware Requirement : Audio Video Development Kit, Stratix IV GX Edition Stratix IV GX FPGA development board and SDI HSMC
The parameters °ENABLE_DUPLEX_PMA_DIRECT" is only supported in this Lib.
This parameter is not exist if you are instantiating a new SDI Duplex Instance.
sdi_megacore_top_inst.ENABLE_DUPLEX_PMA_DIRECT = 1'b1, // Support for PMA DIrect
sdi_megacore_top_inst.ENABLE_DUPLEX_PMA_DIRECT = 1'b0, // Support for Regular Transceiver Channel
Starting Channel Number:
The starting channel number for each instance is incremented by factor 8, eg: 0,8,16,24,32,40
Limitation of this reference design:
-Only Support for SDI Duplex Instance
-Fitting Test is only done for one transceiver quad, as shown in this reference design.
Only SDI Channel 0 and Channel 1 on the design are completely tested. The behaviour of SDI in PMA Direct Mode can be demonstrated through the 2 channels of HSMC daughter card.
SDI Channel 2 to Channel 5 are designed for fitting test, to show that SDI in PMA Direct Mode can be fitted in 4 regular channels and 2 CMU Channel in the same Quad. Due to hardware limitation, not all transceiver quads can fully fit this design.
