National Semiconductor to Feature New, Industry-Leading Low-Jitter Analog Products for Professional and Broadcast Video at IBC 2007

What: National demonstrates its high-performance analog chips at IBC

Where: Booth No. 441 in Hall 11, at RAI Center Amsterdam, Netherlands

When: September 7-11, 2007

Aug 29, 2007

August 29, 2007 - National Semiconductor Corporation (NYSE:NSM) will showcase its latest low-jitter digital and analog video products for the professional and broadcast markets at the International Broadcasting Convention (IBC), September 7-11, 2007, in Amsterdam, Netherlands.

National will demonstrate several new, industry-first analog technologies in its booth, including 3 Gbps (3G) serial digital interface (SDI) products addressing the new Society of Motion Picture and Television Engineers (SMPTE) 424M specification; the industry's first discrete 3G multi-rate SDI serializer and deserializer (SerDes); a high-bandwidth analog video switcher that extends video resolution to QXGA and beyond; a triple operational amplifier and buffer, and low-voltage differential signaling (LVDS) and analog crosspoint switches.

National Broadcast Video Demonstrations - Booth 441 in Hall 11

  • 3G SDI Serializer and Deserializer: With the industry's first discrete 3G multi-rate SDI serializer and deserializer (SerDes), National highlights the exceptional jitter performance of this new chipset interfaced with both Xilinx Spartan 3E and Altera Cyclone III field-programmable gate arrays (FPGAs).  
  • 3G SDI Small Router Chipset: National demonstrates its entire 3 Gbps SDI serial signal path consisting of an equalizer, 4 x 4 LVDS crosspoint switch, reclocker and cable driver.  A signal generator will drive a video signal over a long length of coaxial cable and a variety of board conditions.  The signal will attenuate and accumulate jitter after traveling over the cable at high serial data rates. National's chipset will automatically detect the incoming data rate and adapt to provide optimum levels of signal conditioning to reconstruct the waveform integrity and display the ultra-low jitter waveforms on a signal analyzer.  
  • Analog Video Switcher: Designers can increase picture resolution in various wideband video applications, including routers, matrix switchers, security/surveillance systems and video distribution. The 16 x 8 analog crosspoint switch provides the industry’s highest bandwidth (500 MHz), giving systems the bandwidth needed to extend video resolution to QXGA (2048 x 1536) and beyond. In addition, the low channel-to-channel crosstalk of -48 dBc at 100 MHz improves picture clarity by minimizing video artifacts and shadows from adjacent channels.  
  • High-Definition Analog Video Over CAT-5 Cable:  Utilizing National’s new 500 MHz crosspoint switches and 1 GHz triple amplifiers, National demonstrates a high-definition 4:1 CAT-5 multiplexer.  The demonstration will utilize two 8 x 4 crosspoint switches expanded into a 16 x 4 configuration, demonstrating the ease of expansion with the devices’ diagonally symmetrical pinout.  Customers will see high-definition video transmitted differentially over CAT-5, through the crosspoint switches, over another CAT-5 cable, and onto an LCD display, demonstrating the products’ ample bandwidth for high-definition and high-resolution video CAT-5 applications.  
  • Low-Jitter Sync Separator: The LMH1981 multi-format video synchronization separator offers the industry’s best jitter performance, allowing designers to accurately and precisely extract horizontal and vertical sync signals without extra filtering and jitter-cleaning stages. The chip performs all the necessary sync separation to generate low-jitter horizontal and vertical sync signals for NTSC, PAL, 480i/p, 720p and 1080i/p video formats. The demonstration’s close-up view of the H-sync output’s falling edge highlights the low peak-to-peak jitter performance.
