Communications Technology

Connectivity is a key feature of modern embedded products. There’s a wide range of communications modes that can be used, but which is the best for your design? Should you use a wireless technology such as Wi-Fi or Bluetooth and, if so, which one should that be? Or would wired communication, such as Ethernet, be the best way forward?

In this section, New Electronics reviews the latest communications technologies and brings visitors to the website information on how these technologies are being applied.

Intersil announces isolated RS-485 transceiver

An isolated RS-485 differential bus transceiver has been designed by Intersil to provide 4Mbit/s bidirectional data transmission for industrial IoT (IIoT) networks. The ISL32704E delivers electromagnetic interference and common-mode transient immunity in a 4 x 5mm QSOP package that is said to be 70% smaller than competitive devices.

Bluetooth low energy portfolio expanded

Delivering more available memory, Bluetooth 5-ready hardware, automotive qualification and an ultra-small wafer-chip-scale package option, the CC2640R2F and CC2640R2F-Q1 have been added to Texas Instruments’ scalable SimpleLink Bluetooth low energy CC264x wireless MCU family.

Bluetooth and NFC module for rapid EIoT development

Alpha Micro has begun distributing a certified Bluetooth Low Energy v4.2 and near field communication module, the Laird BL652. The compact stand-alone module is said to offer multiple interfaces and an easy-to-use application development environment for secure connectivity integration without impacting power budgets or space limitations.

Yokogawa updates optical spectrum analysis portfolio

With a diffraction grating based monochromator delivering high-precision measurement performance and accuracy, an enhanced user interface and an air purging feature, the AQ6374 from Yokogawa is a wideband optical spectrum analyser said to be a powerful benchtop tool for general purpose measurements over wavelengths ranging from 350 to 1750 nm.

Anritsu launches BER test solution for 100G-EPON

Anritsu has launched a plug-in modular bit error rate (BER) tester for measuring a range of interfaces up to multichannel 64Gbit/s. Called the MP1800A, the device supports BER measurements of Optical Line Terminal (OLT) and Optical Network Unit (ONU) for the latest 100G-EPON standard.

Bluetooth 5 compatible silicon RF IP

A Bluetooth Low Energy (BLE) RF from CSEM is said to have been fully validated as Bluetooth 5 compatible. The IcyTRX silicon RF IP was developed through a partnership with Rohde & Schwarz.

Binder snap-in, waterproof, modular connectors

The Binder 620 and 720 sub-miniature and miniature all-plastic snap-in modular connectors are available from Foremost Electronics. The lightweight and compact non-connected closed (NCC) design features internal seals that provide protection to IP67 industrial and medical connectors.

GTK offers flat flexible cables

GTK has enhanced its flexible connectivity solutions to include Flat Flexible Cables (FFC). These cables are primarily used to connect two PCBs and are said to be versatile, cost-effective and to take up minimum space in OEM equipment.

Home automation reference designs

Two wireless occupancy sensor and smart outlet reference designs from Silicon Labs address the home automation market. According to the company, the designs – pre-certified by the US FCC and UL – include all the hardware, firmware and software tools required to create connected home products based on its ZigBee ‘Golden Unit’ Home Automation (HA 1.2) software stack and the EFR32MG Mighty Gecko SoC.

Modular connector for CAN based networks

A Controller Area Network (CAN) module has been added to HARTING’s range of Han-Modular ID smart connectors. CAN is a bus system for automation and control which features a number of advantages such as high functional reliability and the ability to operate in harsh conditions.

Artesyn launches 700W DC/DC converter module

Artesyn Embedded Technologies has launched the ADH700 series, a 700W half brick DC/DC converter module. The first model to be made available will offer a 28V nominal output and has been designed to support the popular use of LDMOS technology used in high power wireless base station deployments.

Wideband signal analysis solution

The RSA7100A wideband signal analysis solution from Tektronix can store up to two hours of data from an 800MHz bandwidth feed. Covering frequencies ranging from 16kHz to 26.5GHz, the device is said to address a broad range of analysis needs.

Plessey extends beam-forming LED module family

Plessey has added to its range of ultra-slim Orion LED modules based on its Stellar beam forming technology, with new beam angles opening the technology up to a wider range of applications in both industrial and architectural lighting design.

Long range receiver for the IoT

The latest radio chip for the IoT from STMicroelectronics is said to deliver high energy efficiency allowing smart connected objects to operate for up to 10 years without replacing batteries. With receiver sensitivity of -130dBm, the chip can operate over distances up to several hundred kilometres.
