National Semiconductor to Demonstrate Energy-Saving Professional and Broadcast Video Products at NAB 2009
What: National demonstrates energy-saving, system PowerWise(R) solutions at NAB
Where: Booth SU2804 at
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, LMH0356 reclocker and LMH0303 cable 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(R)-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(R) 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 ML571-1982CLK reference 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.
