Multi-protocol industrial Ethernet switch reduces system integration time

Wed, Oct 12, 2022

To address the connectivity needs of industrial and process automation, motion control, transportation, and energy automation, Analog Devices (ADI) has introduced the ADIN2299. This is a multi-protocol industrial Ethernet switch designed to operate in a star, line, or ring topology. It supports ProfiNet, EtherCat, EtherNet/IP and Modbus TCP.

The ADIN2299 contains a communications controller, a two port 10/100Mbits per second Ethernet switch, memory, physical layer (PHY) and protocol stacks. The ADIN2299 hardware, coupled with its software and pre-certified industrial protocols, reduces system integration time while providing fast time to market, claimed ADI.

Time to design and debug time is reduced through the provision of the protocol stack but also the RTOS, file system, drivers and TCP/IP. An application processor can connect to the switch platform via a UART, SPI or Ethernet interface.

The ADIN2299 software enables the application processor to connect to a unified interface so that various industrial protocols can be used without requiring any changes to the application processor software. This eliminates the learning curve associated with incorporating additional protocols, said the company. Customers can now leverage a single field device hardware design to support multiple industrial protocols.

For cybersecurity, the ADIN2299 has a secure boot and secure update feature which ensures that only verified code is executed to reduce possible disruptions from cyber attacks.

An ADIN2299 evaluation kit is available for platform assessment and system development. An application example is provided to demonstrate end-to-end, host-to-network and interface-to controller communication. Once an application development board is connected via UART, SPI, or Ethernet interface with the ADIN2299 evaluation board, protocol communication can be evaluated using a PLC or controller simulator. This allows for a complete verification before integrating the ADIN2299 into a system, confirmed ADI.

The small form factor ADIN2299 has supplied in a 194 CSPBGA package.

The ADIN2299 is in full production now.

Analog Devices provides a suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies, serving customers in the industrial, communications, automotive, and consumer markets.

2K2K square resolution CMOS image sensor maximises vertical coverage

Wed, Oct 12, 2022

For security wide-field of view and AR / VR / MR pass-through cameras, Omnivision’s first 2K2K (2048 x 2048) square resolution CMOS image sensor introduces features to the industry. The OS04E10 is claimed to be the industry’s first image sensor with digital watermarking, a built-in anti-spoofing feature that ensures no tampering with the original video source takes place.

The 2.0 micron pixel image sensor is designed for 1:1 aspect ratio security systems to maximise vertical coverage in security wide-field of view (dome, fisheye, and doorbell) cameras as well as pass-through (AR / VR / MR) cameras. The sensor captures real-time fast-moving video and features always-on low power mode at 512p for pre-roll video recording capabilities.

Security has become the largest CMOS image sensor market segment after mobile and computing devices. From 2021 to 2027, according to Yole Intelligence’s Imaging for Security 2022 report, this market segment is expected to grow from $2.1 billion to $3.6 billion at a 9 per cent compound annual growth rate (CAGR).

“Pairing the OS04E10 with Omnivision’s OA7600 and OA8000 [ASICs] provides a total battery-powered camera system with always-on and pre-roll video recording capabilitie,” said Devang Patel, marketing director for the IoT and emerging segment at Omnivision.

The OS04E10 image sensor has a 2.0 micron pixel with a 1/3.11-inch optical format and is based on Omnivision’s PureCelPlus technology, which is claimed to reduce pixel crosstalk and noise for better colour reproduction under low-light conditions. Its onboard Nyxel near-infrared (NIR) technology ensures low to no ambient light image capture with IR source will result in clear and crisp images. It can also provide opportunities for camera designers to extend battery life. The sensor’s two-exposure staggered HDR mode increases dynamic range. The OS04E10 supports MIPI and LVDS interfaces.

Samples of the OS04E10 are available now, and it will be in mass production in the second half of 2023.
