October 21, 2008 -- GigOptix LLC, provider of electronic engines for the optically connected digital world, today announced that it has sent the final design for its 100G parallel VCSEL [Vertical Cavity Surface Emitting Laser] drivers and TIAs [Transimpedance Amplifiers] to fabrication. Parts will be available for delivery in January 2009.
The run represents new 12-channel PMDs: the HXT4112A (12 x 10G) VCSEL driver and the HXR4112A (12 x 10G) TIA. The parallel VCSEL drivers and TIAs will enable a new generation of low cost active cable products, note company representatives, who say the 100G PMDs are ideally suited to the growing market for chip-to-chip and board-to-board applications that require very high data throughput that cannot be serviced by copper.
Other traditional applications include: IEEE 802.3ba (pre-standard) Ethernet transceivers; InfiniBand QDR transceivers and active cables; and backward compatibility with DDR applications at 5 and 6 Gbits/sec.
According to the company, discussions with key customers led to improved performance and optimized power consumption in all designs for this run. The power consumption for the HXR4112A has been reduced to 56mW per channel, while the HXT4112A power consumption has been reduced to 63mW per channel--representing an overall reduction of approximately 30% per channel. In addition, four different power output settings were added to the TIA to allow the device to serve multiple reaches and PC board fanouts. The 10G TIA will also have the ability to be used in both limiting and linear modes, allowing it to be used in the widest number of applications, GigOptix contends.
"We are excited to be leading the industry and supplying customers for production early in 2009Iwith 100G silicon," reports Julie Tipton, vice president of marketing at GigOptix. "By using our signature parallel technology and design, we have created parts that facilitate the transition from copper to optical connections in chip-to-chip and board-to-board applications."
