400G-capable optical transceiver increases 400G and 100G infrastructure

To address the demands of enterprises worldwide, seeking to deliver faster speeds and higher bandwidth, AddOn Networks has introduced the QSFP28-DD 2x100G optical transceiver. It increases network density, reduces infrastructure investments and solves interoperability issues between current and future infrastructure, claims AddOn.

“At a time when new technologies such as 5G are driving greater traffic onto networks, it is vital that enterprises and data centres deliver high-quality, large-capacity connectivity to meet the needs of businesses and consumers,” said Patrick Beard, chief technology officer at AddOn Networks. The QSFP28-DD 2x100G transceiver enables network expansion at a multitude of levels while keeping expansion costs to a minimum, he added.

The QSFP28-DD 2x100G transceiver provides enterprises facing scaling challenges the upgrade to a 400G PAM4 infrastructure. It is also suitable for customers who require an interim step as they wait for a more mature solution, advises AddOn. The QSFP28-DD 2x100G solves the interoperability problems that have been experienced between legacy infrastructures and newer systems by using two non-return to zero (NRZ) connectors for compatibility to deliver bandwidth and speed upgrades.

The QSFP28-DD 2x100G transceiver consists of a high-density CS connector and contains two 100G transceivers in one housing, enabling the subtending of two common 100G NRZ to the network. Two 100G transceivers offer flexibility for future-proofing infrastructure and allow enterprises to invest in the relieving of network bottlenecks at minimal expense, says AddOn. The transceiver is also interoperable with existing 100G-CWDM4, 100G-LR4 and 100G-4WDM10 transceivers.

Ethernet 800G Verification IP meets networking demands

Meeting the increases in bandwidth for video-on-demand, social networking and cloud services, Synopsys has introduced the Native System Verilog Ethernet VIP to complement its 112G high-speed SerDes PHY IP to enable high-performance cloud computing. It is claimed to be the industry’s first verification IP (VIP) and Universal Verification Methodology (UVM) source code test suite for Ethernet 800G.

The Synopsys VC VIP for Ethernet 800G is based on the Ethernet Technology Consortium (ETC) specification. It enables SoC teams to design next-generation networking chips for data centres with ease of use and fast integration, to accelerate verification closure and time-to-market. The VC VIP is used to verify Synopsys’ DesignWare 56G Ethernet, 112G Ethernet, and 112G USR/XSR PHYs for FinFET processes, which designers can integrate into 800G SoCs.

The ETC standard provides specifications for an 800G implementation based on eight lane x 100Gbits per second technology, enabling adopters to deploy advanced high bandwidth interoperable Ethernet technologies.

Francois Balay, president of MorethanIP, believes the Synopsys VC VIP will prove an advantage to developers. “Being first in the industry, Synopsys VIP, source code test suite and DesignWare IP for Ethernet 800G strengthens the ecosystem and facilitates early adoption of the technology and fast development of high-speed networking applications,” he said.

Synopsys VC VIP for Ethernet uses a native System Verilog UVM architecture, protocol-aware debug and source code test suites. It can switch speed configurations dynamically at run time and includes an extensive and customisable set of frame generation and error injection capabilities. Source code UNH-IOL test suites are available for key Ethernet features and clauses, to facilitate custom testing and accelerate verification closure.

Synopsys VC VIP and source code test suite for Ethernet 800G are both available today as early access standalone products. The DesignWare 56G and 112G Ethernet PHYs are available now and the silicon design kit for the DesignWare USR/XSR PHY IP in 7nm FinFET process is also available.

Differential WiFi oscilloscopes enable mobile measurements

Two differential WiFi oscilloscopes have been added to the WiFiScope series by TiePie. The high resolution WiFiScope WS6 Diff and WiFiScope WS4 Diff are everyday oscilloscopes, says the company, which can be used via an Ethernet connection (LAN, WiFi or WAN) and with a USB 2.0 / 3.0 connection.

They have a built-in battery which allows the WiFiScope the possibility to perform fully wireless differential measurements. Measurements can then be performed galvanically isolated and over long distances. The wireless, PC-based data acquisition instruments can be used for serial communication buses, switch mode power supplies, frequency converters and automotive measurements.

With a WAN connection, worldwide differential measurements can be performed. Specific knowledge on networks is not required, says TiePie. The Multi Channel software gives an overview of the available USB instruments and network instruments.

The differential WiFi oscilloscope provide fully wireless differential measurements via WiFi and mobile differential measurements (e.g. on transport systems and moving installations) are also possible. LAN and WAN data acquisition is available for long distance differential measurements.

The e.g. on transport systems and moving installations also provide continuous real time high speed data acquisition over both WiFi and LAN/WAN and USB differential measurements for standalone applications. High speed data acquisition is up to 200Msamples per second.

According to TiePie, the WiFiScope is so transparent that it appears that the Ethernet connected instrument is connected directly to the computer. All hardware and software functions of the oscilloscope, spectrum analyser, data logger and voltmeter remain available via the network.

The differential WiFi oscilloscope can now be used where previously it was difficult to place a complete measurement setup, says TiePie. The WiFi connections enable electrical, physical, mechanical and acoustic signals to now be measured remotely. With the WiFi oscilloscope, high speed real time continuous data acquisition rates of 5Msamples per second can be achieved with a resolution of 8- to 16-bits and, via LAN / WAN connections, high speed real time continuous data acquisition rates of 20Msamples per second can be achieved with a resolution of 8 to 16-bits. Via USB connections, high speed real time continuous data acquisition rates of 200Msamples per second can be achieved with a resolution of 8 to 16bits.

When combined with the free Multi Channel oscilloscope software, the WiFiScope WS4 Diff and WiFiScope WS6 Diff turn a PC into a high resolution differential oscilloscope, precision spectrum analyser, EMI pre compliance analyser, high performance multimeter, very fast differential data logger and comprehensive protocol analyser. The Multi Channel software allows the user to share data and analyse it without the need of an instrument. The software’s data analysis capabilities, via user configurable data processing I/O blocks, show the analysis results in graphs, tables and/or meter displays. Complicated instrument setups are no longer required as the Quick Setup accomplishes the measurement task in up to four mouse clicks from a selection dialogue that gives access to over 700 set ups, containing settings, example signals and background information on how to connect the instrument.

A software development kit (SDK) for writing PC-based data acquisition software is available, as well as examples in C, C++, C#, Python, Matlab, Node.js and Visual Basic.NET.

It has a full speed (12Mbits per second) USB 2.0 interface. The USB connectivity interface enables low-latency and high-bandwidth communication with a range of host devices, such as PCs, smartphones, and gateways. The connectivity also makes device firmware updates (DFU)-over-USB practical. In addition to the main supply regulators, the USB peripheral in the nRF52820 includes a dedicated regulator for converting the 5V Vbus signal to the 3.3V needed for the USB signalling interface, which negates the need for an external regulator, saving both cost and space.

Based on a 64MHz 32bit Arm Cortex-M4 processor, the SoC includes 256kbyte Flash and 32kbyte RAM. This, says Nordic, makes it particularly well-suited as a single-chip option for commercial and industrial wireless applications including professional lighting, asset tracking, high intensity discharge lighting and gaming products.

When paired with an application microcontroller, the nRF52820’s multi-protocol radio and +8dBm output power enables its use as a network processor for gateways and other smart home applications that require advanced wireless connectivity.

The nRF52820 is qualified for operation across an extended industrial temperature range of -40 to 105 degrees C.

The nRF52820 includes up to 18 general purpose I/Os and a range of analogue and digital interfaces such an analogue comparator, SPI, UART, TWI, and QDEC.

The supply voltage covers a 1.7 to 5.5V input range, allowing the nRF52820 to be powered by coin-cells and rechargeable batteries.

The nRF52820 is supported by the S112 and S140 SoftDevices (Bluetooth 5.1-qualified protocol stacks), and the S122 (alpha version) SoftDevice. The S112 and S122 are memory-optimised peripheral and central stacks respectively, while the S140 is a feature-complete Bluetooth 5 protocol stack for central and peripheral, including long range and high-throughput.

Nordic also offers the nRF5 software development kit (SDK) v16.0.0, with the full nRF5 SDK support to follow in Q2 2020. The nRF52833 development kit can be used to emulate the nRF52820 and as a basis to start nRF52820-based designs.
