  • What is USB 3.1?

    Considerable time has passed since the finalisation of USB 3.1 specification in August 2013 where an announcement was made that it would double USB 3.0 theoretical transfer speeds to 10 Gbps and support scalable power delivery of up to 100 Watt using the USB Power Delivery spec. Here is the clarification of current situation:

    Quick points about USB 3.1

    • USB 3.1, at the moment, has two versions:
      Gen 1 - “SuperSpeed USB” - basically the same as USB 3.0 with 5 GBit/s bandwidth
      Gen 2 - “SuperSpeed USB 10 Gbps” - future upgrade that needs chips that are yet unavailable
    • All current USB 3.1 devices should be backward compatible with USB 3.0 and USB 2.0
    • USB 3.1 does not include the Type-C connector - it is optional
    • USB 3.1 does not include USB Power Delivery - it is optional
    • USB 3.1 refers to the transfer rates of USB products
    • USB3 Vision standard is not affected by USB 3.1 specification update.
    • Lambda Photometrics are shipping XIMEA USB 3.1 Gen 1 machine vision cameras

    Latest News

    • USB 3.1 Gen 2 will add an optional 10 Gbit/s transfer rate.
    • Gen 2 throughput is approximately 2.5 times higher than USB 3.0 due to more effective new data encoding scheme - actual rate of 1 Gigabyte per second.
    • For now, USB 3.1 Gen 2 cables have the maximum length of 1 meter.
    • USB-IF certified USB 3.1 Gen 2 devices will use a new SuperSpeed USB 10 Gbps logo which you can see below.
    • USB 3.1 1.0 specification was published July 2013.
    • Introduction of new connectors with enhanced EMI contact zones that are designed to minimise RF leakage. Radiated interference from the USB interface and susceptibility to other RF sources are improved. Backward compatible with previous ones.
    • Revision 3.x
    • USB 3.1 capable products will begin to ship in the first half of 2015, partly due to the backing of companies as Microsoft, Intel and Apple. Officials in the European Union and China have approved the verification procedures for USB 3.1 which should help the technology come to market sooner than expected.
    • At Computex 2015 Intel showcased that company has abandoned its proprietary connector replacing it with the super-fast Thunderbolt standard and adopted USB Type-C connectors to supercharge the reversible cable.
    • Intel’s Thunderbolt USB Type-C cable delivers 40Gbps  Comparison:
    Note: Not all USB Type-C cables will have equal parameters

    Note: Not all USB Type-C cables will have equal parameters

    • Thunderbolt 3 will be backward compatible with USB 3.1 Type-C ports by integrating USB 3.1 controller into the cable making it able to be used on any USB Type-C port.
    • There will several Thunderbolt 3 cable options:
      Passive 20Gbps copper cable based on the existing USB Type-C cable with up to 2 meter length,
      Active 40Gbps copper cable with up to 2 meters,
      Optical Fibre cable 40Gbps for lengths up to 60 meters (planned for 2016).
    • USB Type-C ports are able to support many different protocols using system aptly called “alternate modes”. This interesting feature means: you can have adapters that can output HDMI, VGA, DisplayPort, or other connections from single USB port (last Apple MacBook provides this with USB Type-C Digital Multiport Adaptor), which represents fewer types of ports on the host device in the future - further miniaturization.

    SuperSpeed+

    The full claim in distributed was that:
    "SuperSpeed USB 10 Gbps uses a more efficient data encoding and will deliver more than twice the effective data through-put performance of existing SuperSpeed USB over enhanced, fully backward compatible USB connectors and cables. Compatibility is assured with existing USB 3.0 software stacks and device class protocols as well as with existing 5Gbps hubs and devices and USB 2.0 products."

    As you can see in the logo, the new upgrade is referred to as "SuperSpeed+" and while a lot of work has already been done, there is still some time before this will transfer into products.

    USB Promoter Group already organized and will be holding continuous developer conferences to further promote the standard.

    XIMEA team was already present on several conferences and plans to keep this practice to follow the newest progress and ensure that our partners and customers receive the most up to date information and exceptional products based on the most modern technology that is available at the moment.

    Reversible USB Type-C connector

    In addition to previous USB Promoter Group announcements, there is a separate category which notified that design of the USB Type-C plug is finalised. This new type of USB plug deserves special attention since it is supposed to completely replace every USB connector type of any size that is currently available. Many people compare it to Apple's Lightning cables because the new connector is also reversible and can be used inserted in any orientation.
    After USB Type-C finalisation, which IT world quickly adopted, it is possible to see already available devices, cables, adapters and other accessories that support the new reversible connector. Few examples are: latest Apple MacBook has one, latest Chromebook Pixel  with two USB Type-C ports, HP Pavilion x2, Nokia’s N1 tablet etc.

    Reference footprint for a USB type-C mid-mount dual-row SMT receptacle (informative)

    Note: USB Type-C cables and ports may be used for USB 3.1, BUT, depending on the host controller and devices, the also may only be compatible with USB 2.0 or USB 3.0

    Summarising the USB-IF’s press release, the new connector is "similar in size" to current micro USB 2.0 Type-B connectors (the ones you use for most non-Apple phones and tablets). It is designed to be "robust enough for laptops and tablets" and "slim enough for mobile phones." The openings for the connector measure 8.4mm by 2.6mm.

    USB Type-C connector has 18 pins and is basically a unification of two USB 3.1 SuperSpeed connectors (these have four pins and additional five to enable 10Gbps). Simply put - if you plug the connector one way one set of pins is used and if you reverse it the other set is used.

    USB type-C to USB 2.0 standard-A cable assembly

    An important side-note is that cables and adapters connecting older Type-A and Type-B ports to Type-C devices will be readily available. Also, the USB Type-C connector is designed taking into consideration the possibility to scale when USB spec gets faster - increasing the bandwidth and length beyond USB 3.1 For further comfort, there will also be new USB cables that have a USB Type-C connector at both ends.

    Power

    A huge benefit, which is often neglected, is that USB Type-C connector allows delivery of up to 100 watts through the USB cable - that is enough to charge 4K monitor, most peripherals and in fact laptop itself. The USB Promoter Group claims the USB Type-C connector is rated as Micro-USB to 10,000 cycles. Another claim is that design is supposed to be future-proof so will be part and parcel of any USB versions in the years ahead.

    Note: USB Type-C can support USB Power Delivery if the device’s host controller and the cable itself support the standard, but the fact that you have USB Type-C does not mean you automatically have USB Power Delivery.

    The new USB Power Delivery specification had a parallel development to USB 3.1 which is also why, like the Type-C connector, USB Power Delivery is separate from the USB 3.1 specification.
    Together with the USB Power Delivery standard there will arrive new PD-aware cables.
    These will have an interesting feature called “handshake” - which will happen between a host and device. Device itself can request up to 20V at 5A from the host, but before the host can deliver more than 5v at 900mA, it will check if the cable is able to safely deliver the requested power.

    Note: Ports that will support respective USB Power Delivery profiles with voltages greater than 5V, or currents greater than 1.5A, would be marked with an according logo.

    Bandwidth

    USB Type-C supports USB 2.0, USB 3.1 Gen 1 (SuperSpeed USB 5 Gb/s), and USB 3.1 Gen 2 (SuperSpeed USB 10 Gb/s) data speeds.
    Note: USB 2.0 and USB 3.1 are defined under separate specifications.

  • XIMEA releases new camera models with Sony CMOS sensors and USB3

    XIMEA, the innovator of small size and high speed cameras, has released more models with Sony CMOS Pregius™sensors and USB3 Vision.

    It started with models based on IMX174, IMX252 and IMX250, and now XIMEA has made accessible to the general public the first units with Sony CMOS IMX255 sensor providing 8.9 Mpix at 43 Fps - MC089MG-SY / MC089CG-SY, as well as cameras using the Sony IMX253 sensor with 12.4 Mpix at 31 Fps - MC124MG-SY / MC124CG-SY. These newcomers are part of the xiC line of cameras enhanced with the ever popular USB3 interface.

    All Sony’s models from the IMX family based on the Pregius™ technology have Global shutter and are able to supply 8, 10 or 12 bit high quality pictures with the Dynamic range higher than 70 dB, extraordinarily low noise, exceptional light sensitivity and remarkable colour reproduction, at a speed much higher than Sony CCD equivalents.

    To leverage the impressive image quality of the newest Sony sensors and their high speed using USB3, XIMEA has cast these ingredients into an extra small form factor housing, measuring only 26x26x33 mm and weighing just 38 grams. Power requirements are as low as 3 Watt which allows the cameras to be bus powered directly through the USB3 cable.

    The interface is specified as “USB 3.1 Gen 1” and there is no practical difference from the well-known USB 3.0, still ensuring a high bandwidth of 5 Gbit/s. XIMEA offers various types of connectors - the default being standard USB 3.0 Micro-B, but it is also possible to supply camera variations with the new USB Type-C or Flex line connector ideal for embedded vision systems.

    Free of charge, the XIMEA API/SDK supports Windows, Linux, Mac OSX and the most popular Machine Vision Libraries including MVTec Halcon, National Instruments Labview, OpenCV and Mathworks Matlab. An interesting option is a combination these miniature cameras with Linux ARM boards to further enhance the mobility of the overall system package.

    Next level of speed, unbeatable form factor, attractive price, compatibility and customisability make XIMEA USB3 Vision cameras stand out from the crowd and will also make your applications shine.

  • Onefive releases a new 100W picosecond laser, the Genki – 10 XP, for advanced material processing

    Lambda Photometrics are pleased to announce release of the new Genki – 10 XP picosecond laser from Onefive GmbH, featuring 100W output power in a new and compact package for optimal and cost-effective workstation integration.

    The Genki – 10 XP platform further advances the industrialisation of high energy and high power picosecond lasers. Based on Onefive’s ultra-stable Genki seed laser, this new laser provides clean pulses shorter than 10 ps, which is an optimal pulse duration for many micromachining applications. To satisfy the increasing demand for picosecond laser workstations, the Genki – 10 XP has been optimised to provide up to 100 W of average power and 300 μJ pulse energy at the industry-standard wavelength of 1064 nm. Wavelength conversion options are available for 532nm and 355nm. Pulse repetition rates from single-shot up to 80 MHz can be achieved, together with burst-mode operation, and this laser can also be tailored to work at lower repetition rates with even higher pulse energies.

    The Genki – 10 XP has been designed to provide the simplest and most cost-effective possible system integration. It is an all-in-one design containing seed laser, amplifier and driving/timing electronics in one box. The laser can be completely controlled by RS232 offering full remote control capability. It offers excellent pointing stability and is maintenance-free.

    Picosecond laser-based micromachining and industrial production is proven to have several advantages for quality control, high-precision, and lack of post production needs. Nevertheless high-power pulsed lasers remain expensive and complex for many standard industrial processes. The Genki – 10 XP has been developed to remove these constraints offering a compact, cost-effective and long lasting product. It has been especially designed for micro-machining and several other industrial applications, and was shown for the first time at Photonics West 2017 in San Francisco.

  • Functional conductive nanomaterials via polymerisation in nano-channels: PEDOT in a MOF

    BSE-SEM images and EDS mapping were acquired on a Phenom ProX Desktop microscope with an accelerating voltage of 5–15 kV for BSE-SEM images and 15 kV for EDS mapping.

    Tiesheng Wang, Meisam Farajollahi, Sebastian Henke, Tongtong Zhu, Sneha R. Bajpe,a Shijing Sun,a Jonathan S. Barnard, June Sang Lee, John D. W. Madden, Anthony K. Cheethama and Stoyan K. Smoukov

    Reactions inside the pores of metal–organic frameworks (MOFs) offer potential for controlling polymer structures with regularity to sub-nanometre scales. We report a wet-chemistry route to poly-3,4-ethylenedioxythiophene (PEDOT)–MOF composites. After a twostep removal of the MOF template we obtain unique and stable macroscale structures of this conductive polymer with some nanoscale regularity.
