DESIGN & PRODUCTS MISCELLANEOUS Peraso aims WiGig reference design at smartphones Peraso Technologies has introduced what it claims to be the first mobile WiGig USB adapter reference design, based on its W120 phased array chipset. The reference design aimed at smartphone vendors enables users to add 802.11ad capability through a USB connector. The reference design enables a series of WiGig applications paired with the smartphone market, including Rapid Sideloading (which can be used to download an HD movie in under 10 seconds) and Mobile VR where WiGig can provide a wireless, private and secure connection between a smartphone VR headset and a remote device such as a laptop or tablet. This allows users to access significantly more content that can be stored on a smartphone, while utilizing the superior GPU horsepower of the remote system. The high data rates and excellent power efficiency provided by 802.11ad makes WiGig suitable for streaming 4K video but also for multi-Gigabit Wi-Fi networking. Peraso Technologies www.perasotech.com IP65-rated wire-to-wire connector supports 11A Molex’ ValuSeal wire-to-wire connector system is an IP65- rated, integrated wire-and-ring seal system capable of carrying 11A for consumer, nonautomotive transportation and lighting applications. The built-in seals moulded into the connector protect against water and dust ingress. Crimpand poke insertion simplifies wire assembly for added cost efficiency, and the integrated wire strain-relief in the connector body prevents leak-paths often found in other connector systems. The compact 4.00mm pitch offers design flexibility in limited space environments. The 2-circuit connector is currently available, and a 4-circuit version will follow by mid-2017. Molex www.molex.com DCM converters in a ChiP package The DCM in a ChiP package is an isolated, regulated DC-DC converter operating from an unregulated, wide range input to generate an isolated DC output. With its high frequency zerovoltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across the input line range. Aimed at a variety of applications, including UAV, ground vehicle, radar, transportation and industrial controls, Vicor has added a new 30V input nominal module (9 to 50V range) in a 3623 ChiP package measuring 38.6x22.9x7.4mm. This converter has an output voltage of 15V maximum power of 160W, achieving a power density of 404 W/in3. Also announced is a 375W module with a nominal input voltage of 275V (120 to 420V) and 24V output in a 4623 ChiP package measuring 48x22.9x7.4mm, achieving a power density of 775 W/in3. Vicor www.vicorpower.com 0.35mm thin haptic actuator operates at up to 200Hz TDK has expanded its portfolio of haptic components with a 0.35mm thin PiezoHapt actuator featuring a response time of just 4ms. PiezoHapt has a unimorph design consisting of a multilayer piezo element bonded to one side of a vibration plate. Much thinner than conventional eccentric rotary motors and linear resonant actuators, the device can be driven with low voltages under 24V and can produce a wide variety of vibration patterns, depending on the amplitude and frequency of the voltage applied. The PHUA8060-35A-33-000 type has a footprint of 80x60mm (vibration plate). At a frequency of 200Hz (sine-wave) and a voltage of 24V peak, the component offers a typical displacement of 55μm. PiezoHapt is suitable for providing haptic feedback to user actions in the displays of smartphones and tablets. TDK www.tdk.com “moth-eye” film improves displays’ visual appearance andersDX announced a cost-effective 7” PCAP touchscreen display module with a “moth eye” film surface treatment that increases the display’s readability over a wide viewing angle (50°x70°x70°x70° typical), even in high ambient light conditions. The moth eye film surface treatment mimics the microsized lenses in the eye of a moth, it reduces internal reflections between the display and the PCAP touchscreen, improving visual appearance and ensuring that the display looks completely black when turned off. The moth-eye film’s nanostructures achieve very low levels of reflectivity over the entire visible spectrum. The film can be applied to other TFT modules up to 10.1”, with no tooling cost or minimum order quantity. The 7” display module has a resolution of 800RGBx400 and a colour depth of 16M. The transmissive display includes a capacitive touch panel. andersDX www.andersdx.com 48 Electronic Engineering Times Europe March 2017 www.electronics-eetimes.com
