GigOptix intros GX3101 universal transimpedance amplifier

Feb. 17, 2010
FEBRUARY 17, 2010 -- GigOptix Inc. (OTCBB:GGOX) has released the GX3101, a universal limiting transimpedance amplifier (TIA) designed for use in fiber-optic communication systems such as Fibre Channel, Ethernet, and SONET transceivers and in wireless backhaul.

FEBRUARY 17, 2010 -- GigOptix Inc. (OTCBB:GGOX) has released the GX3101, a universal limiting transimpedance amplifier (TIA) designed for use in fiber-optic communication systems such as Fibre Channel, Ethernet, and SONET transceivers and in wireless backhaul. The GX3101 is designed to enable one device to support a variety of optical reaches, speeds, and standards that require a limiting TIA.

Key features of the GX3101 include:

  • bandwidth selection to support operation from 2 to 11 Gbps
  • high sensitivity with 16 kOhm differential gain to support up to 80-km reaches
  • AGC and DC cancellation circuitry to ensure high performance over a large range of operating conditions
  • what GigOptix described as a large output voltage swing to eliminate the need for a post amplifier
  • low power consumption

The GX3101 is designed to help simplify ROSA manufacturers’ supply chains by enabling the use of one part to address a wide range of speeds, reaches, and standards that have previously been addressed by different TIAs from multiple vendors. The universal TIA also enables manufacturers to enjoy cost efficiencies by leveraging the combined purchase of high-volume/low data rate applications with the smaller but growing 10-Gbps network applications, GigOptix says.

“The GX3101 is being very well received by our optical transceiver customers. It was developed in close collaboration with a leading ROSA manufacturer to ensure that it would cover as wide as possible range of applications,” commented Julie Tipton, vice president, marketing at GigOptix. ”GigOptix initially developed the device for the Ethernet and Fibre Channel market segments, and we are now beginning to see significant demand for the device from 3G/4G wireless backhaul segment operating at [a] 6-Gbps data rate. This segment is moving to higher-capacity optical fiber implementations to satisfy consumers’ fast growing demand for mobile audio and video services.”

The GX3101 is now available for sampling and will be in full production in Q2 2010.
