GigOptix GX3220 TIA for 40G and 100G applications

PALO ALTO, USA: GigOptix Inc., a leading provider of electronic engines for the optically connected digital world announced the availability for sampling of the GX3220, a 28Gb/s linear transimpedance amplifier (TIA) with integrated automatic gain control for 100G DP-QPSK and 40G DQPSK applications.

“The GX3220 is a very low power, small form factor solution that more than addresses customers’ functionality requirements,” commented Padraig O’Mathuna, Director of Product Marketing at GigOptix.

“The 100G transponder standardization is still under way and power dissipation is a major concern amongst the defining group. We feel that we have not only met the current low power dissipation requirement but have successfully surpassed it. The excellent performance and extreme low power of this TIA ensures that it is strongly positioned relative to our competition.”

Key features of the GX3220 include:
* Frequency range up to 28Gb/s.
* High linearity and low harmonic distortion compliant with the draft 100G OIF recommendations.
* Supports a variety of photodiodes from vendors.
* Very low power consumption.

Ovum's most recent WAN optical components market forecast projects that the volume of 40G receivers will grow from 20K units in 2009 to 183K in 2013 (CAGR 74 percent) with the 100G WAN optical component market showing similar growth rates starting from 2010.
