TriQuint launches 1st 32G SMT differential modulator driver with low power consumption for extending reach of 40G optical networks

RF front-end product and foundry services provider TriQuint Semiconductor Inc of Hillsboro, OR, USA has released what is claimed to be first 32Gb/s surface-mount differential modulator driver amplifier with the lowest power dissipation available for ultra-long distance optical networks.

The new driver amplifier is designed to extend the reach of 40Gb/s optical networks; extended reach is a key benefit of the DP-BPSK (dual-polarization binary phase-shift keying) modulation format, employed for ultra-long-distance optical fiber networks, says TriQuint. The TGA4959-SL supports both DP-BPSK and the differential quadrature phase-shift keying (DQPSK) optical modulation formats.

TriQuint claims to have set the standard for 40Gb/s and 100Gb/s optical modulator drivers with its TGA4943-SL, the first high-performance surface-mount driver amplifier for metro and long-haul fiber-optic networks. Availability of the TGA4959-SL extends TriQuint’s portfolio to support new modulation formats while offering a modulator driver amplifier with differential output amplitude, adjustable from 6Vpp to 9Vpp. In addition to low power dissipation (just 2.2W for Vout = 8Vpp at Vd=5V), the TGA4959-SL also provides system-critical benefits including low rail ripple, high-voltage capability and very low output jitter, says the firm. Additive RMA jitter is 580fs, gain is 24dB at 16GHz, and rise and fall times are 13ps. The package size is 10mm x 7mm x 3.2mm. Samples and evaluation boards are available.

TriQuint is attending the European Conference and Exhibition on Optical Communications (ECOC 2011) in Geneva, Switzerland this week (19-21 September).
