JULY 30, 2009 -- GigOptix Inc. (search Lightwave for GigOptix) has announced the availability for sampling of the GX3220, a 28-Gbps linear transimpedance amplifier (TIA) with integrated automatic gain control for 100-Gbps DP-QPSK and 40-Gbps DQPSK applications.
The company announced the device earlier this month as part of a new family of TIAs.
"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."
According to GigOptix, key features of the GX3220 include:
- frequency range up to 28 Gbps
- high linearity and low harmonic distortion compliant with the draft 100G OIF recommendations
- support of a variety of photodiodes from vendors
- very low power consumption
Samples of the GX3220 are now available in die form.
