National Semiconductor to Demonstrate Energy-Saving Professional and Broadcast Video Products at NAB 2009

Apr 9, 2009

What: National demonstrates energy-saving, system PowerWise® solutions at NAB
Where: Booth SU2804 at Las Vegas Convention Center, Las Vegas, Nevada
When: April 20-23, 2009

April 9, 2009 – National Semiconductor Corp. (NYSE:NSM) will showcase its energy-saving products for the professional and broadcast video markets at the National Association of Broadcasters (NAB) show, April 20-23, 2009, in Las Vegas, Nevada. National will conduct live demonstrations that include a new 3 Gbps (3G) serial digital interface (SDI) adaptive cable equalizer, PowerWise® SDI distribution amplifier, triple-rate development kits for the leading field-programmable gate arrays (FPGAs), a video clock module for the Xilinx Virtex®-5 development platform and new chip-scale packages (CSP) for triple-rate (SD/HD/3G) SDI equalizer, reclocker and cable driver.

National Broadcast Video Demonstrations — Booth SU2804

  • PowerWise 3G-SDI Equalizer:National will demonstrate the advanced features of the industry’s most energy-efficient SDI equalizer (EQ) via a serial peripheral interface (SPI) control bus accessing the chip’s registers. Product features include an auto-sleep mode that delivers 85 percent power consumption savings, wider input amplitude range down to 400 mV, low-power LVDS driver with adjustable output amplitude, cable length indicator to detect the amount of cable at the input and settable output common-mode voltages for DC coupling to downstream blocks. The EQ offers two modes of operation: in pin-mode, the EQ is backward-compatible with existing solutions, while the register-mode offers access to a suite of advanced features to optimize energy-efficiency, detect operating parameters and customize performance.
  • PowerWise Distribution Amplifier (DA):Demonstration of industry-leading jitter performance across multiple cable lengths using a waveform monitor and jitter analyzer. National’s DA extends the reach of incoming signals up to 140m at 3G rates, 200m at high-definition (HD) rates and 400m at standard-definition (SD) rates to optimize connectivity of broadcast studio equipment. The DA consists of National’s new 3G-SDI adaptive cable EQ, LMH0356reclocker and LMH0303cable driver. In the event of cable detachment or loss of signal at the DA’s input or output, the system automatically enters a deep power-save mode, enabling a 90 percent savings in power consumption.
  • 3G-SDI Up-Converter:Demonstration of a high-performance SD-SDI to 3G-SDI up-converter that showcases scaling with a low-cost FPGA. The demo uses a video daughter card developed by Avnet and National (AES-EXP-SDI-G) along with a Xilinx Spartan®-3A development kit, National’s FPGA source code and proprietary third-party IP and hardware. The up-converter also converts SDI to HDMI, underscoring the complex processing achieved without the use of an expensive, high-end FPGA. The system transmits the video data through an Altera Stratix® III FPGA development board, validating cross-platform compliance and demonstrating simplicity in porting National’s FPGA code to different platforms.
  • Triple-Rate SDI Video Reference Design:Demonstration of a complete video reference design for triple-rate (3G/HD/SD) SDI applications using National’s ML571-1982CLKreference design clock module in combination with a Xilinx ML571 Virtex-5 development board. The ML571-1982CLK delivers the industry’s lowest clock output jitter of 40 ps peak-to-peak (at 148.5 MHz) to drive the Virtex-5 LXT FPGA’s integrated SerDes without the need for additional clock cleaning circuitry. The reference design module features National’s highly integrated LMH1982 multi-rate video clock generator and LMH1981 sync separator. The LMH1982 produces a top of frame (TOF) timing pulse output and can generate two simultaneous SD and HD output clocks genlocked to the recovered H and V syncs from either a Xilinx Virtex-5 LXT FPGA, or from the outputs of the LMH1981.
  • New Miniature Packages for National’s triple-rate SDI EQ, reclocker and cable driver. These packages reduce IC footprint up to 49 percent for increased port density and simplified layout in multi-channel or space-constrained applications such as video routers, switchers, cameras and distribution amplifiers.
