Single-chip 14G VCSEL driver and dual-path limiting amplifier

Maxim has introduced the MAX3799, a single-chip VCSEL driver and dual-path limiting-amplifier solution targeted at SFP+ Ethernet and Fibre Channel applications. Fabricated using Maxim’s MBiC3 IC technology, this device delivers up to 14Gbps performance, a wide range of programmable receiver and transmitter features, and only 320mW of power consumption. Packing the functions of two chips into one, the MAX3799 provides a low-cost, low-power solution optimized for Ethernet 1000BASE-SR/10GBASE-SR and 2x/4x/8x/16x Fibre Channel transmission systems, thus simplifying transceiver BOM for module manufacturers.

A 3-wire digital interface provides a wide range of programmable features to optimize performance. Programmable receive functions include data rate, LOS threshold, LOS squelch, LOS polarity, CML output level, signal-path polarity, slew-rate control, deemphasis, and mode-select change time. Programmable transmit functions include modulation current, bias current, polarity, deemphasis, eye-crossing adjustment, and eye safety control.

The MAX3799 is fully specified for operation over the -40 degrees Celsius to +85 degrees Celsius extended temperature range, and is available in a 5mm x 5mm, 32-pin TQFN package.

Rio de Janeiro announcement from The City of Rio de Janeiro and X, The Moonshot Factory, Taara announced a trailblasing new partnership to deploy the world’s first mesh network of high-speed wireless optical links to deliver fast, abundant and secure connectivity to schools, hospitals and city offices in Rio. Our goal is to bridge connectivity gaps across the city and provide fast, affordable connectivity to critical services like schools, hospitals, government centres, and in disaster response situations. In the same way traditional fibre uses light to carry data through cables in the ground, Taara uses narrow, invisible beams of light to transmit information at speeds as high as 20 gigabits per second, up to distances of 20 kilometres per link. Taara connects into existing fibre networks and bridges the gap where fibre and other technologies can’t reach. Instead of waiting months or years to dig up the earth and lay new fibre cables, Taara’s links can be established within hours. In Rio de Janeiro, Taara will install 20+ links to deliver service to communities where connectivity is spotty or unreliable. The links will create an invisible mesh network over parts of the city that will serve as a single responsive system – connecting community institutions like schools and hospitals and helping facilitate emergency response. A new approach for urban connectivity in Rio Although Brazil ranks among the world’s five largest internet economies, connectivity remains spotty – more than half of the population uses smartphones to get online, and existing cellular infrastructure varies by community. In Rio, some of the most stubborn, hard-to-connect areas are also the city’s most populated. Built of brick, concrete, and steel rooftops through a labyrinthine tangle of narrow streets and uneven terrain, it’s nearly impossible to connect these communities via traditional broadband fibre. Taara’s links, which can be mounted flexibly on rooftops, towers, and poles, are well suited to these challenging terrains and combine the reliability and speed of fibre infrastructure with the flexibility of wireless technologies. To date, Taara has successfully delivered reliable, abundant internet to people in more than 20 countries. This includes providing access in dense urban communities in India and Africa, delivering fast affordable connectivity to island nations in the Pacific and the Caribbean after natural disasters, and beaming connectivity over rivers, sea straits, and other places where laying fibre is too impractical or costly. Taara is honoured to be supporting Rio’s AI City vision and its mission to transform the region into a global innovation hub. We hope Taara’s first mesh network in Rio can serve as a blueprint for urban connectivity and inspire a more connected, intelligent, and inclusive world.
