TriQuint expands industry’s largest SMT optical modulator driver portfolio with 100-200 Gb/s solutions

September 25, 2013

TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, announced four new optical network products that expand the company’s industry-leading portfolio with miniaturized and integrated modules.  TriQuint high performance optical components reduce overall system costs, simplify RF design and shrink board space for today’s 100 Gb/s optical fiber networks and future 200/400G systems.

In a market once dominated by connectorized modules four or five times the size of TriQuint’s surface mount technology (SMT) modulator drivers, it’s easy to see why smaller, more economical solutions continue to win market share. While legacy ‘gold brick’ modules once met needs, they were complex to assemble, burdened by high cost and power dissipation, while also demanding substantial PCB real-estate.

TriQuint introduced the first SMT modulator drivers for high-capacity optical networks, and has since built the industry’s largest product portfolio. TriQuint solutions offer higher performance, ease of manufacturing, greater efficiency and integrated functionality. TriQuint’s unique semiconductor passivation technology enables modulator drivers and other products to endure harsh conditions better than any other, which lowers maintenance and extends operational lifetimes.  

“As we expand our optical product portfolio, we remain committed to improving the performance and lowering system costs for our customers. TriQuint solutions continue to set RF performance and reliability standards for current 100G and next-generation high capacity networks required to support the exponential growth in video and data demand,” remarked James L. Klein, Vice President and General Manager for Infrastructure and Defense Products.

Infonetics Research forecasts continued growth for 100G networks and components, particularly for lower cost formats such as CFP2. “Operators no longer view 100G as an exotic technology and the market is entering a new stage of growth where lower equipment cost is a critical catalyst to wider adoption. Lower cost 100G networks will accelerate adoption of the technology into higher volume parts of the market, such as the metro. High performance, surface-mount solutions like TriQuint’s continue to play key roles in the transition to 100G systems and beyond,” said Infonetics’ Andrew Schmitt, Principal Analyst, Optical.

New TriQuint Solutions

TGA4894-SL– TriQuint’s new lead-less SMTdual-channel linear driver reduces part counts by half compared to single-channel devices while meeting the higher order 16 QAM (quadrature amplitude modulation) requirements for 200/400G systems; it is based on TriQuint’s proven single-channel solutions. The new TGA4894-SL exhibits high gain, low Total Harmonic Distortion (THD) and high channel-to-channel isolation. The TGA4894-SL’s high gain (33dB) is a key benefit. When paired with commonly utilized / low-power DACs, it provides sufficient gain to deliver more than 7Vpp to industry-standard modulators; this results in low THD (<3%), a key requirement for 200/400G systems.

TGA4957-SM– TriQuint’s TGA4957-SM is designed for 40/100G long-haul and regional markets as well as ultra-long haul (1000-4000+km) systems employing DP-BPSK modulation. It reduces the device footprint by 50% compared to prior generations.

TGA4840-SM– This new modulator driver provides world-class power dissipation not exceeding 165mW for 32G baud rates in a miniaturized form factor. This enables TriQuint to grow its portfolio into short-reach / access network applications including those connecting smartphones and tablets. The TGA4840-SM is ideal for ‘hot pluggable’ modules supporting the CFP2/CFP4 standards that are one-half to one-quarter the size of standard CFP modules.

TGA2565-SM– TriQuint’s new SMT wideband clock driver covers three key frequencies: 11.3, 14.5 and 16.5 GHz. The TGA2565-SM integrates analog gain control (AGC) that eliminates an off-chip component and utilizes industry standard plastic encapsulated SMT packaging. This solution reduces part counts while covering three frequencies with one product.
