To implement an UHD-SDI interface in a 7 series
GTX FPGA, perform the following steps:
- Generate a GTX wrapper, a GTX common wrapper, and a CPLL railing module using the 7 Series FPGAs Transceivers Wizard.
- Generate the SMPTE UHD-SDI core.
- Instance the UHD-SDI wrapper from this application note into the application. The UHD-SDI wrapper instances and interconnects the GTX wrapper, the UHD-SDI core, and the SDI control logic. The GTX common wrapper must be instantiated separately and connected to all UHD-SDI wrappers in the same GTX Quad.
- Apply proper timing constraints to the UHD-SDI interfaces.
