TriQuint expands SMT optical modulator driver portfolio with new 100-200Gb/s solutions

RF front-end component maker and foundry services provider TriQuint Semiconductor Inc of Hillsboro, OR, USA has introduced four new optical network products to its portfolio with miniaturized and integrated modules.

TGA4894-SL: TriQuint’s new lead-less SMT dual-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 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: 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. 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 16.5GHz. 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.
TriQuint representatives will be available at ECOC in London, UK on 25 September in Meeting Room 9.

“As we expand our optical product portfolio, we remain committed to improving the performance and lowering system costs for our customers,” remarks James L. Klein, VP & general manager for Infrastructure and Defense Products. “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.”

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,” says Infonetics’ Andrew Schmitt, principal analyst, Optical. “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.”
