Native SDI Signals - 2.0 English

These signals are available when the Video Interface is set to Native SDI in the Vivado IDE. The native SDI also supports an AXI4-Lite control interface. When the AXI4-Lite control interface is enabled, some ports are not available as noted in the following table. This configuration is similar to the transmitter of the SMPTE UHD-SDI IP core in terms of functionality, and therefore for further information, see the SMPTE UHD-SDI LogiCORE IP Product Guide (PG205).

Important: In Native SDI mode, the image data values must be constrained to avoid SDI prohibited codes. You must avoid the values from 00h to 003h and 3FCh to 3FFh. In Native Video mode and AXI4-Stream mode, the image data values below 004h (000h to 003h) are clamped at 004h, and the values above 3FBh (3FCh to 3FFh) are clamped at 3FBh internally, to avoid the SDI prohibited codes.

See the TX Ports section of the SMPTE UHD-SDI LogiCORE IP Product Guide (PG205) for more details on the signal descriptions. Enabled only when the Enable AXI4-Lite interface option is not selected in the Vivado IDE. Enabled only when the Insert ST352 in C stream option is selected in the Vivado IDE. Enabled only when Native SDI is selected as the video interface and 12G SDI 16DS is selected as the SDI standard.
