GigOptix debuts low-power 14G VCSEL driver, TIA for SFP+

SEPTEMBER 9, 2010 -- GigOptix, Inc. (OTCBB:GGOX) has announced the sampling of its new pre-production chipset for short-reach 2- to 14-Gbps serial optical interconnects. GigOptix asserts its latest offering provides a complete serial link chipset for applications up to 14 Gbps.

The GigOptix chipset comprises the HXT4101A VCSEL driver and the HXR4101A multi-rate receiver. The chipset is designed to not only enable low power consumption of less than 150 mW for 100-m links and 250 mW for 300-m links but also minimize the components required to implement a transceiver in order to reduce costs.

The HXR4101A receiver is a limiting transimpedance amplifier (TIA) with pre-emphasis output designed to eliminate the need for the post amplifier required in current alternatives; it supports multiple rates from 2 to 14 Gbps, making it suitable for systems requiring backward compatibility.

The HXT4101A VCSEL driver supports up to 14-Gbps data rates while consuming less than 65 mW, delivering 7-mA average and 7-mA modulation current.

The designs enable applications to extend from datacom into avionic and consumer applications.

"We are very excited to introduce this new chipset solution that uniquely addresses the current and future datacom short-reach needs," stated Jörg Wieland, vice president and general manager of GigOptix-Helix, Zurich. "We developed these highly innovative products to address customer demand for high performance, lower power, and better cost-efficient solutions."
