 designers a two-chip, end-to-end solution that simplifies design and reduces cost in security DVRs. Direct connection is made possible through the MAX9530's integrated memory controller, which assembles four channels into a single optimally formatted data stream for H.264 compression. Unlike other four-channel decoders that rely on the compression engine to reformat all four channels separately for compression, the MAX9530 performs this function automatically in advance to preserve critical video processor performance.
Analogue-to-digital conversion (video decoding and audio conversion) is the first step in the signal path for any system that accepts analogue video/audio inputs and incorporates digital processing. Video decoders and audio ADCs are therefore critical in determining the level of video and audio quality available downstream for compression and further processing. The MAX9530 features a 54MHz 10-bit ADC, differential inputs, video equaliser and interchannel crosstalk of greater than 60dB. The differential analogue inputs improve noise immunity on dense digital boards, easing system layout and design. Its four-channel digital EQ function restores high-frequency losses on each video input to maintain signal integrity in applications with long cables.
Tektronix has announced the DPO/DSA/MSO70000C Series of digital and mixed signal oscilloscopes to offer more accurate signal integrity measurements for high-speed serial standards. These devices now deliver 100GS/s sampling rate performance; enabling lower noise along with increased data points on 5x over-sampled 20GHz acquisitions. High-performance oscilloscopes with a bandwidth greater than 4GHz are used in a variety of high-speed serial, wideband radar, fast optical communications systems, high-end embedded systems and high-energy physics applications.
The DPO/DSA/MSO70000C Series can provide the performance and signal fidelity designers need to ensure that their latest components and systems meet design specifications. Along with a two-fold increase in sampling rate compared to the 'B' Series it replaces, the DPO/DSA/MSO70000C Series features a faster compute platform. This new platform offers faster processing for longer data records such as jitter, noise, BER (bit error rate) measurements and statistics. Boot and application start-up times are also much quicker.
In any digital oscilloscope, there is a strong correlation between sampling rate and internal noise - a high sampling rate results in less noise, which in turn leads to more margin for the user. As shown by comparison testing, the DPO/DSA/MSO70000C Series with 100GS/s operation delivers up to 20 per cent reduction in noise compared to the 50GS/s setting on the same instrument. Modern radar designs use frequency and phase modulation within the radar pulses to increase a radar's range resolution and target identification capabilities. Maintaining the same modulation characteristics from pulse to pulse is key to the system's operation.
Performance oscilloscopes are the tool of choice for radar pulse measurement, but must have a stable timebase able to stay on frequency for long captures. The DPO/DSA/MSO70000C Series meets this requirement with a new high-stability timebase that provides for lower long-term jitter, phase and frequency stability. When combined with the pulse and frequency settling measurement capabilities of SignalVu vector signal analysis software, the DPO/DSA/MSO70000C Series gives designers of frequency agile radios and radars the ability to accurately verify system performance.
The DPO/DSA/MSO70000C Series oscilloscopes provide the bandwidth and sampling rates needed to debug serial data signals up to 12Gb/s on all channels simultaneously - ideal for multi-lane applications including PCI Express 3, SATA 6Gb/s, Superspeed USB, HDMI, Displayport and 10Gb Ethernet. The Fastacq acquisition mode provides a capture rate greater than 300,000 waveforms per second - delivering both critical insight into signal behaviour and in-depth analysis.
Rogers Corporation's Poron Shockseal foams are engineered to meet the cushioning, sealing and protection requirements of large LCD displays. Poron Shockseal foam is available as thin as 0.5mm and conforms to some of the smallest and most intricate manufacturing designs. Poron materials help safeguard electronic devices and the Poron Shockseal series offers even greater impact protection for sensitive applications.
Poron Shockseal foam reduces impact force by more than four times that of competitive materials, according to Rogers. These foams have the same compression set resistance as other Poron materials and the same compressibility as the Poron 92 formulation. This allows them to maintain spring forces over time and effectively seal out dust and other harmful particles.
Aitech Defense Systems has introduced a 6U VPX SBC suitable for radar system boot computers, sonar processors, video and graphics engines and single-board process and machine control applications. The SBC offers the selection between PCI Express or Serial Rapid IO (SRIO) and a host of on-board I/O ports. Using an integrated dual-core PowerPC processor, the single-slot C110 combines low power performance with increased memory capabilities.
It is built to OpenVPX (VITA 65) and VPX (VITA 46.0) specifications and is fully compliant with legacy VME operations, such as VME64 per VITA 46.1, while supporting advanced VME protocols including 2eSST and 2eVME. Four ports, configurable to either Serial RapidIO (SRIO) or PCI Express (PCIe), make up the VPX core backplane fabric. Via the I2C bus, the VPX connectors also provide system level management monitoring of the board's status, including monitoring key rail voltages and temperatures.
The C110's on-board I/O resources include four Gigabit Ethernet, four USB 2.0 ports, two SATA 2.0 ports, six asynchronous serial ports and eight GPIO (general-purpose discrete I/O) channels. The board comes with two PMC/XMC slots and an optional Aitech I/O module (AIOM) slot for the installation of user-customised I/O interfaces. The MPC 8640D processor features dual e600 cores operating at 1.25GHz, each with 64kB of L1 and 1MB of L2 on-chip, high-speed cache. Additional memory includes a large, fast 2GB bank of dual-channel DDR2 SDRAM with ECC, 128MB of user Flash for firmware, user application and data storage functions as well as 8GB of high-density NAND Flash memory for mass storage.
Withstanding extreme military shock and vibration over an extended temperature range of -55C to +85C (Mil-Spec), the C110 remains reliable in extreme environmental conditions. The board's thermal management design enables optimal heat dissipation across the board and heat rejection from the card edges, regardless of whether the board is conduction or convection cooled. Real-time operating systems (RTOS) are available for the C110 include Wind River VXWorks, Green Hills Integrity and Linux.
BI Technologies offers a series of custom thin-film resistor networks in hermetically-sealed metal or HTCC (high-temperature cofired ceramic) packages. The Model 144 Series high-reliability resistor networks can be specified with custom schematics, non-standard resistance values and ultra-tight resistance and TCR tolerances to meet the requirements for military electronics systems, avionics and aerospace circuits.
According to Mike Torres, fixed-film product manager for BI Technologies Electronic Components Division, the Model 144 Series thin-film custom resistor networks provide tighter resistance tolerances and TCR tracking performance than other precision networks. 'We can produce custom networks with up to 25 resistors that mix and match resistor values based on the customer's requirements,' he said. 'And, through our processing and packaging, we can achieve ratio tolerances between individual resistors in the network to less than +/-0.01 per cent and TCR tracking tolerances to less than +/-1ppm/C,' he added.
The networks' construction and packaging is designed specifically for high-reliability applications where plastic packaged devices cannot be specified due to elevated temperatures or other harsh environmental conditions. Available in hermetically sealed through-hole DIP and surface-mount flat-pack packages with three to 28 pins, the Model 144 Series networks also features a passivation coating over the precision nichrome resistive elements to protect against humid environments, and the package cavity is filled with inert nitrogen.
The custom high-reliability resistor networks are suitable for a wide range of applications, including instrumentation amplifiers, precision voltage dividers, measurement bridge circuitry, ladder networks and other precision analogue circuits in aerospace and military electronic systems. The Model 144 Series custom resistor networks feature resistance values from 10ohms to 3Mohms, in tolerances down to +/-0.025 per cent (ratio tolerances to +/-0.01 per cent), in ratio values up to 1:1,000.
Typical TCRs are +/-25ppm/C, with tracking between resistors available to +/-1ppm/C. Operating temperature range is from -55C to +175C. Screening and testing to MIL-STD-883, MIL-STD-1835, MIL-PRF-38534, MIL-STD-38510 and MIL-STD-202 is available on request. The Model 144 Series networks can also be ordered in RoHS-compliant versions. Typical lead times for the Model 144 Series custom resistor networks are from 10 to 16 weeks, with no minimum order quantity required.
