2. SDI II Intel® FPGA IP Design Example Detailed Description
The SDI II Intel® FPGA IP core includes these design examples for Intel® Arria® 10 devices.
- Parallel loopback with external VCXO
- Parallel loopback without external VCXO
- Serial loopback
Features
- For HD/3G-SDI single rate and triple rate designs, you can choose either CMU or fPLL as the TX PLL.
- All designs use LED status for early debugging stage.
- The simplex serial loopback designs include RX and TX options. To use RX or TX only components, remove the irrelevant blocks from the designs.
User Requirement Preserve Remove RX Only RX Top - TX Top
- Transceiver Arbiter
TX Only TX Top - RX Top
- Transceiver Arbiter
Note: You can directly connect the Avalon-MM pins at the RX or TX Top as shown in the diagram below.
