GigOptix Inc. has started sampling two new chip sets for short-reach 14GB/s serial optical interconnects.

GigOptix said the 4- and 12-channel 14Gb/s link chip set solutions for next generation Infiniband Fast Data Rate (FDR) Active Optical Cables (AOC), which operate up to 168Gb/s as well as 40G and 100G Ethernet transceivers, are designed datacom, avionics and consumer markets.

The chip sets are comprised of a 4-channel HXT5104 VCSEL driver and HXR5104 receiver amplifier chip set and a 12-channel HXT5112 VCSEL driver and HXR5112 receiver amplifier chip set.

GigOptix said the chip sets are designed to enable ultra-low power consumption of less than 450mW for a 40G link over 100m as well as minimize the components required to implement a transceiver, which results in lower costs.

The HXT/R5 family incorporates programmable equalization and pre-emphasis circuitry to facilitate various trace lengths in addition to providing full programmable control via fully integrated Analog to Digital Convertors (ADC) and Digital to Analog Convertors (DAC) through an industry standard 2-wire interface, said GigOptix.

"The new devices integrate more functionality than our previous generation, while dissipating less power with improved performance in terms of eye quality, or optical output, and receiver sensitivity," said Martin Bossard, GigOptix director of engineering and GigOptix-Helix AG general manager.
