Multi-speed PoE injector supports Wi-Fi 6 infrastructure

Tue, Aug 03, 2021

The EKI-2701MPI-5G is a compact, industrial grade injector by Advantech which delivers Wi-Fi 6 network infrastructure, power over Ethernet (PoE) and advanced connectivity to existing infrastructure. It supports multiple data rates, i.e. 10M / 100M / 1G / 2.5G / 5G (data in) and IEEE802.3bt 90W PoE output. Advantech advised that it can be used for obsolete infrastructure applications requiring heavy network connectivity.

The EKI-2701MPI-5G supports downward-compatible 2.5 and 5Gbits per second data rates to deliver Wi-Fi 6 capabilities to existing wireless infrastructure. It also serves as a PoE power source, delivering up to 90W output to IP cameras, Wi-Fi 6 access points, and other connected devices. The injector’s PoE standard is downward- compatible for 15, 30, and 60W PoE power delivery (PD) devices, which can facilitate network infrastructure upgrades. Using the EKI-2701MPI-5G to upgrade infrastructure saves manpower while reducing cabling weight and cost, added Advantech. The downward-compatible data rate helps extend the life cycle of existing devices, the company said.

The compact, palm-sized form factor is adaptable to network infrastructure upgrades where space is limited. It is capable of delivering network service without overheating and supports a wide operating temperature range of -40 to +75 degrees C.

The injector’s force mode power supports up to 90W by DIP switch, power input of 54 to 57V DC and 90W.

The slim industrial grade metal housing is IP40-rated and is for DIN rail mounting.

Established in 1983, Advantech offers comprehensive system integration, hardware, software, customer-centric design services, embedded systems, automation products, and global logistics support. It co-operates closely with partners for a wide range of applications in diverse industries. The company’s mission is to enable an intelligent planet by developing automated and embedded computing products and solutions that facilitate smarter working and living.

Microchip unveils single chip for network synchronisation

Fri, Jul 30, 2021

Offering precise timing for 5G radio access equipment, the ZL3073x / 63x / 64x network synchronisation platform combines integration and performance in one compact, low-power device, says Microchip.

For 5G, time sources need to be synchronised throughout a packet-switched network 10 times more accurately than 4G requirements. The devices makes it possible to achieve 5G performance with what is claimed to be the first single chip, highly integrated, low power, multi-channel IC coupled with the company’s IEEE 1588 precision time protocol (PTP) and clock recovery algorithm software modules.

The ZL3073x / 63x / 64x network synchronisation platform implements sophisticated measure, calibrate and tune capabilities, which reduces network equipment time error to meet the most stringent 5G requirements, said Rami Kanama, vice president of Microchip’s timing and communications business unit.

Microchip’s measure, calibrate and tune capabilities ensure 5G systems achieve ITU-T Standard G.8273.2 Class C (30ns max|TE|) and the emerging Class D (5ns max|TEL|) time error requirements. The architecture offers up to five independent digital phase locked loop (DPLL) channels while consuming only 0.9W in a compact 9.0 x 9.0mm package that simultaneously reduces board space, power and system complexity.

There are five low-jitter synthesisers which offers 100 femto second root mean square (rms) jitter performance required by high speed interfaces in the latest 5G radio unit, distributed unit and central unit systems.

Microchip’s network synchronisation platform software includes its ZLS30730 high-performance algorithm coupled with its ZLS30390 IEEE 1588-2008 protocol engine. The network synchronisation platform combines seamlessly with Microchip’s family of precision 5G oscillators, adds the company. Its portfolio also includes clock generation, fanout buffer and jitter attenuator solutions as well as quartz and MEMS oscillators and Ethernet physical layer (PHY) devices.

A graphical user interface (GUI) and evaluation board are also available, along with application notes and other design-in support tools.

The ZL3073x / 63x / 64x network synchronisation platform is available in production quantities and offered with IEEE 1588 PTP and algorithm software modules, which are provided through license terms for download.

Neural network detects faces in 12milliseconds

Wed, Jul 28, 2021

Faces can be detected in video and still images at 12 milliseconds per inference in the Detectum neural network created by Xailient. The IoT face detection system uses Maxim Integrated’s MAX78000 AI microcontroller.

Xailient’s neural network draws 250 times  lower power (at just 280 microJoules) than conventional embedded solutions, and at 12 milliseconds per inference, the network performs in real time and is faster than the most efficient face-detection system available for the edge, claims Maxim.

Battery-powered AI systems that require face detection, such as home cameras, industrial grade smart security cameras and retail solutions, require a low power operation to provide the longest possible time between charges. In addition to supporting standalone applications, Maxim Integrated’s microcontroller paired with Xailient’s neural network improves overall power efficiency and battery life of hybrid edge / cloud applications that use a low power ‘listening’ mode which wakes up the more complex systems when a face is detected.

Xailient’s Detectum neural network includes focus, zoom and visual wake word technologies to detect and localise faces in video and images at 76 times faster rates than conventional software, at similar or better accuracy, says Maxim. The ability to localise a face means that it can be used for advanced applications which determine where a face is in the image’s field of view. Examples include person, vehicle and object counting, presence or obstruction detection, as well as path mapping and footfall heatmaps.

The network can be extended to other applications such as livestock inventory and monitoring, parking spot occupancy and retail or warehouse inventory levels.

Xailient’s neural network combined with the computational efficiency and low power sleep modes of the MAX78000 microcontroller extend the operating time of coin cell battery-powered, hybrid edge/cloud applications for many years, says Maxim.

“AI is on track to be the second largest carbon emitting industry,” said Dr. Shivy Yohanandan, Xailient chief technology office (CTO) and inventor of Xailient’s Detectum neural network technology. “Replacing 14 legacy internet protocol cameras that use traditional cloud AI with edge-based cameras equipped with the Maxim Integrated MAX78000 paired with Xailient’s neural network has the equivalent carbon impact of taking one gasoline powered car off the road,” he said.

The MAX78000 is available now and Maxim also offers the MAX78000EVKIT# evaluation kit.

The Detectum neural network, series models, tools, services as well as focus, zoom and visual wake word technologies are available directly from Xailient.

Eight-channel ReDriver has PCIe 4.0 interfaces

Wed, Jul 28, 2021

Extending its linear ReDriver ICs, Diodes has added the PI3UPI1608 with internal coupling capacitors. The IC can “significantly” extend PCB trace lengths while minimising power consumption and associated bill of materials costs, says the company.

It supports speeds of up to 20Gbits per second and is UPI 2.0 and PCIe 4.0- compliant with eight differential channels. Integral coupling capacitors save board area by reducing the number of external components required. can be avoided.

Key applications include AI servers, data storage equipment, 5G networking infrastructure and high-performance PCs as well as CPU-to-CPU and CPU-to-storage interconnects.

The PI3UPI1608 ReDriver compensates for channel losses at the transmitter and improves signal integrity at the receiver. It is also optimised for high-performance systems operating at elevated frequencies.

The programmable linear equalisation, output swing, and flat gain capabilities enable the PI3UPI1608 to reduce bit error rates (BERs) and lower intersymbol interference. Programmability can be carried out via the pin strap and I2C interface.

The PI3UPI1608 ReDriver IC runs off a 3.3V supply and has an operating temperature range of -40 to +85 degrees C. It is supplied in a 116-pin QFN package which measures 13 x 7.0mm.

Diodes delivers semiconductor products to companies in the consumer electronics, computing, communications, industrial, and automotive markets. Its product portfolio includes discrete, analogue and mixed-signal products and packaging technology to meet customers’ needs. There are 31 sites around the world, including engineering, testing, manufacturing, and customer service.
