GigOptix, a provider of high-speed electronic devices, has unveiled a new differential limiting amplifier, GX3240, for use in a 40G RZ-DQPSK receiver and with further applications in the microwave and instrumentation markets.

 

Limiting amplifier, in general, provides gain as well as level shifting and keeps the input voltage within a safe range, thereby making them useful for protecting circuitry that has a limited input range.

 

According to GigOptix officials, the company won this customer’s design based on company’s history of providing high speed, high performance amplifier designs in compact low power form factors.

 

GigOptix latest offering was developed in partnership with a Japanese telecom manufacturer. Available in a 3x3mm QFN form factor, this differential limiting amplifier features a 3dB bandwidth of over 27GHz, 700mVpp differential output as well as low power dissipation.

 

Chief Technology Officer at GigOptix, Andrea Betti-Berutto, said that GX3240 device’s QFN package makes it very manufacturing-friendly. Additionally, its 27GHz bandwidth enables a wide number of demanding applications for company’s customers.

 

GX3240 extends GigOptix’s plastic package QFN limiter family, which includes the iT3011E & iT3018E from 10 GHz bandwidth to 27 GHz bandwidth, added Betti-Berutto.

 

 “The device was designed for the 40G RZ-DQPSK telecom market which is seeing a lot of operator and vendor interest at the moment however, it can also be used in instrumentation markets where it provides a low power high speed buffer that is able to clean up and re-square high speed digital signals,” Betti-Berutto said.

 

According to Lightcounting’s newest Transceiver and Optical Interconnects Market Forecast, it is anticipated that a robust 70 percent CAGR can be expected in the 40G market segment through 2013.

 

“Telecom companies are continuing to invest in network infrastructure despite current economic conditions and are deploying 40G systems to support the increasing bandwidth demanded by consumers using bandwidth hungry applications such as Facebook and Hulu’s (News - Alert) ‘over the top’ IP TV,” Scott Schube, senior analyst at Lightcounting, said.

 

Recently, GigOptix announced that its GPPO connectorized 40G EO polymer Mach-Zehnder Modulator, LX8400, has been shipped in pre-production quantities to a number of defense, research and academic customers.

 

GigOptix said that it has a broad portfolio of high speed electronic devices, such as polymer electro-optic modulators, modulator drivers, laser drivers and TIAs for telecom, datacom, Infiniband and consumer optical systems - covering serial as well as parallel communication technologies from 1G to 120G.
