5.4.2. 3G-SDI (Level B) to HD-SDI Dual Link Conversion

To interface between 3-Gbps single link receiver and HD-SDI dual link transmitter equipment, perform a 3G-SDI (level B) to HD-SDI dual link conversion.

Note: This feature is only available for Arria V, Cyclone V, and Stratix V devices. You can enable this feature through the SDI II parameter editor.

This conversion takes a single 3G‑SDI signal and separates the signal into two 1.485 Gbps signals, which can either be a dual link 1080p signal or two separate co-timed HD data streams.

Figure 27. Example of 3G-SDI (Level B) to HD-SDI Dual Link ConversionThe figure shows the conversion of 3G-SDI (level B) data to two HD-SDI data streams.


Figure 28. Implementation of 3G-SDI (Level B) to HD-SDI Dual Link ConversionThe figure shows a block diagram of 3G-SDI (level B) to HD-SDI dual link conversion.
