Basestation simulator supports next-gen eCall tests

Fri, Jul 12, 2019

To support the next-generation emergency call system (NG-eCall), Anritsu has extended its eCall test. The company has combined a basestation simulator MD8475A/B and the eCall tester MX703330E software, to support the next-generation emergency call system (NG-eCall).

eCall is a pan-European emergency call system for sending information about road accidents to a public safety answering point (PSAP). The European Union (EU) made the fitting of 112-based eCall in-vehicle systems (IVS) to all new M1- and N1-category vehicles mandatory from 31 March 2018.

Current eCall deployments are based on ETSI and CEN standards using an in-band modem to transport eCall data (MSD) over circuit-switched (CS) GSM and UMTS networks. EU operators plan to phase-out support for GSM and UMTS in favour of all-IP infrastructures like LTE and 5G in the next 10 years. eCall support for IP networks has better stability and reliability, notes Anritsu.

Anritsu has added the NG112 LTE eCall option to its eCall tester MX703330E GSM-based eCall test to implement RFC8147-defined NG-eCall function tests and end-to-end voice evaluation.

Anritsu also offers test solutions to validate TCU with eCall functions by supporting 1.0Gbit LTE simulation and NG-eCall tests using one MD8475B unit, providing both optimum coverage for general telematics tests, and helping cut test costs.

Anritsu has provided communications test and measurement solutions for 120 years. It partners with customers to help develop wireless, optical, microwave/RF, and digital solutions for R&D, manufacturing, installation, and maintenance applications, as well as network monitoring and optimisation.

Anritsu also provides precision microwave/RF components, optical devices, and high-speed electrical devices for communication products and systems. The company develops advanced solutions for 5G, M2M, IoT, as well as other emerging and legacy wireline and wireless communication markets.

It has approximately 3,500 employees in over 90 countries.

Fanless touch panel computer installs HMI in tight spaces

Fri, Jul 12, 2019

The GOT107W-319 is a compact seven-inch fanless touch panel computer from Axiomtek which allows easy installation in space-constrained areas, says the company, as well as offers programmable on screen display (OSD) function keys for a variety of application access. The IP65-rated panel PC adopts a seven-inch WSVGA TFT LCD with a projected capacitive touchscreen, 320 nits of brightness and LED backlight. It is powered by the Intel Celeron processor N3350 or Intel Pentium processor N4200 (codename: Apollo Lake). The slim, noise-free, IP65-rated, seven-inch widescreen touch panel PC can be used for digital signage display, self-service kiosk, industrial control and IoT-related applications, advises Axiomtek.

In addition to the IP65-rated front bezel, the rugged GOT107W-319 is equipped with aluminium back chassis, which offers enhanced heat dissipation to ensure stable and reliable operation, says the company. The all-in-one touch panel PC also has five membrane keys on its front bezel, for convenience in LCD on/off, LCD brightness and volume control. It also features RS-232/422/485 with RI/5V/12V selectable by BIOS. There is no need to open the back cover to change jumper settings, adds the company.

I/O connectivity includes one RS-232/422/485 port, one RS-232 port, two gigabit LAN ports with Intel Ethernet Controller I211-AT and two USB 3.0 ports. For wireless network connectivity, the touch panel computer features one PCI Express Mini Card slot and one M.2 Key E slot. There is also one internal mSATA socket and one easily accessible MicroSD card slot to expand storage functionality. In addition, the seven-inch WSVGA panel PC features one 204-pin DDR3L-1600 SO-DIMM with up to 8Gbyte of memory capacity. There is also an easily accessible external switch for AT/ATX mode selection. Multiple mount options including panel mount, wall mount, VESA arm and desktop stand are available for diverse installation requirements. The GOT107W-319 also supports Windows 10.

Axiomtek’s GOT107W-319 will be available in August, 2019.

Connector eliminates wire harness to make room in automotives

Wed, Jul 10, 2019

Panasonic has created a connector that allows direct connection between an automotive flexible printed circuit (FPC) and the board. It eliminates the need for wire harnesses previously needed for connection, allowing the use of fewer components and fewer assembly person-hours for vehicles, as well as making room in the vehicle.

Production of the board to FPC connector (CF1) begins this month. Recent changes in legislation around automotive LED lighting in Europe and Japan have led to an increase in the use of daylight running lamps (DLRs) and improved designs for vehicle compartment instrument panels, for example, in vehicles. As a result, says Panasonic, demand for automotive FPCs is expected to grow, accompanied by greater use in cable connection applications such as battery management systems (BMS).

Although FPCs and boards are conventionally connected mainly by using relay harnesses or by soldering FPCs and boards, there are drawbacks such as the additional weight and poor assembly workability of wire harnesses.

Panasonic has designed the connector with a proprietary metal terminal connection structure, which allows direct connection between the FPC and the board. It eliminates the need for relay harnesses, allowing the use of fewer components and assembly person-hours.

The connector’s double-clip contact structure achieves excellent resistance to vibration, says Panaconic, making it compatible with automotive applications such as LED lights and BMS. The double-clip contact structure grips the plug, i.e., the metal terminal (FPC side), and the receptacle (board side). The connector can also be used for FPCs for connecting BMS battery packs and boards, as well as for LED lights that require resistance to vibration.

The connector’s inertial lock structure prevents incomplete engagement for high reliability.

The connector is rated for 2.0A per pin and 50V DC. It operates in an ambient temperature range of -40 to +125 degrees C.

Contact resistance is 20 mOhm maximum and insulation resistance is 100 MOhm and above.

Maxim’s GMSL SerDes technology extends video transmission in vehicles

Tue, Jul 09, 2019

For video transmissions in vehicles, Maxim Integrated’s gigabit multimedia serial link (GMSL) serialiser and deserialiser (SerDes) technology is used by MediaTek in its Autus in-vehicle infotainment (IVI) platform.

MediaTek’s AUTUS I20 (MT2712) is a high-performance, hexa-core infotainment system and has a flexible interface to support multiple displays. It links drivers to their vehicles to improve the driving experience, passenger safety, connectivity and entertainment, providing information and content from the car’s sensors and multimedia sources.

Maxim’s advanced GMSL SerDes technology delivers robust video distribution for these surround-view applications, says the company. One MAX9286 automotive deserialiser and four MAX96705 serialisers provide synchronised video streams from four cameras via 15 meters of shielded twisted-pair (STP) or coaxial cable.

To support data transmission for auto sensors, entertainment content and navigation, designers required a higher-speed, higher-voltage memory technology. This was achieved using Maxim’s MAX20010 high-current, 6.0A buck converter with dynamic voltage scaling, reports Maxim. It enabled MediaTek to migrate to a higher voltage memory.

Maxim’s GMSL SerDes technology extends data transmission distance from 12 to 15 metres with the MAX9286, and also provides surround-view application support with a single chip via frame synchronisation on four input channels enabling higher system performance by offloading the SoC. Support for MIPI-CSI-2 output enables seamless interoperability with MediaTek’s SoC and spread-spectrum features reduce electromagnetic interference (EMI) to improve safety and performance.

The GMSL SerDes technology provides data integrity over 15 meters.

With dynamic voltage scaling (DVS), Maxim’s MAX20010 high-current buck converter allows Autus I20 designers to upgrade to fast, higher voltage 4Gbyte LPDDR4/DDR4 memory, for sufficient power to support multiple video-rich applications across in-car displays. Maxim’s buck converter also provides skip mode to save power consumption when the MediaTek IVI is running at light load.

Maxim Integrated develops analogue and mixed-signal products and technologies to make systems smaller and smarter, with enhanced security and increased energy efficiency. The company powers design innovation for customers in automotive, industrial, healthcare, mobile consumer, and cloud data centre markets.
