Phabrix Limited used Xilinx, Inc. (Nasdaq: XLNX) low-cost, low-power programmable solutions to enable their handheld 3G-SDI test signal analyzers. The multi-format instrument is the first portable test signal analyzer to support standard definition (SD), high definition (HD), and emerging 3G serial digital interface (SDI) standards. Phabrix combined the Spartan-3A FPGA with National Semiconductor’s 3G-SDI serializer and deserializer to create an optimized and cost-effective SDI solution.
The Phabrix design team leveraged the integrated features of Xilinx Spartan(R)-3A field programmable gate arrays (FPGAs) and CoolRunner(TM)-II complex programmable logic devices (CPLDs) to integrate audio and video functionality with rugged reliability into their latest generators, analyzers, and monitors.
Field programmability not only played a vital role in enabling Phabrix to adapt to the rapidly evolving standards and feature requirements of the broadcast market, Xilinx FPGAs made it possible for Phabrix customers to receive automated firmware upgrades through the Phabrix website.
Both the Phabrix-Sx handheld and Phabrix-Rx 2U rack mounted systems incorporate a wide range of advanced functions, including: SDI test signal generation and TX; zone plate generation, video RX analysis and capture; video scaling for all 3G/HD/SD SDI video formats on a 4.3″ TFT display; video keying and mixing; EDH/CRC insertion and analysis; scrambling; word alignment; waveform monitor and vector display; PLL control and clock generation; audio embedding, de-embedding and processing.
