Zipcores FMC-SDI Mezzanine Card
Zipcores FMC-SDI Mezzanine Card is a dual-channel SDI video-signal transceiver. The two SDI inputs are fully independent and can de-serialize all standard SMPTE serial video formats up to 2.97Gbps. Likewise, the two SDI outputs are fully independent and support all the standard SMPTE formats up to 2.97Gbps.
Example standards include 3G-SDI (SMPTE 424M), HD-SDI (SMPTE 292M), ED-SDI (SMPTE 344M), SD-SDI (SMPTE 259M) and also DVBASI stream. The card conforms to the ANSI/VITA 57.1 FMC™ mezzanine specification, allowing connection to a wide range of baseboards and FMC-compliant systems. Examples include development boards from AMD/Xilinx®, Intel/Altera®, Avnet®, Digilent® and Microchip®. The FMC-SDI card may easily be scaled up to provide four or more SDI video input and output channels for evaluation boards with two or more FMC connectors.
One key advantage of the FMC-SDI card is its simple LVDS interface with the baseboard or host system. This means the card is suitable for a wide range of FPGA and SoC devices that don’t feature high-speed serial transceivers. Examples include the lower-cost Zynq-7000 SoCs and Spartan-7 FPGAs from AMD/Xilinx and the low-cost, low-power Cyclone 10 series from Intel/Altera. In addition, the card features adaptive cable equalization to allow long cable lengths of over 30 meters at 3G-SDI speeds. Finally, the card also performs full recovery of the video pixel clock. This makes the card ideal for video processing, switching, and pass-through applications without needing a video frame buffer or external clock synchronization circuitry.
