GigOptix’s 45G differential limiting amplifier enters mass production

GigOptix Inc of Palo Alto, CA, which designs modulator and laser drivers and transimpedance amplifier (TIA) ICs based on III-V materials as well as polymer electro-optic modulators, says that its GX3440, a 45Gb/s differential limiting amplifier announced in April 2009, is now shipping in full production.

The GX3440 was designed to be used in 40G DPSK (differential phase-shift keying) and 40G DQPSK (differential quadrature phase-shift keying) telecom receivers and can also be used in instrumentation applications. GigOptix says that it is the first of its family of differential and transimpedance amplifiers to be released to production this year that comprehensively addresses customers’ requirements for telecom and datacom receiver amplifier solutions.

Key features of the GX3440 include: low power dissipation, high input sensitivity, broad bandwidth to accommodate up to 44.6Gb/s, and large differential output voltage.

“The design and development for this high-performance 40G DPSK balanced receiver was driven by a leading Japanese 40G ROSA [receive optical sub-assembly] manufacturer based on our proven history of producing high-speed designs,” says chief technology officer Andrea Betti-Berutto. “The GX3440’s high-performance design enables our customer to meet the exacting requirements of 40G telecom receivers.”

In its latest transceiver and optical interconnects market morecast, market research firm Lightcounting predicts strong market growth at a compound annual growth rate (CAGR) of 70% for the 40G market segment through 2013.
