Fairchild Semiconductor announced that its FIN24AC ?SerDes has been selected for use in LG Electronics' new "Chocolate" phones, the first series of LG's Black Label cellphones. According to Fairchild, the FIN24AC was chosen for its ability to ease design complexity, reduce size, lower EMI and save battery-power.

"LG's latest slim-slide style cellphones are only 14.9mm thick and provide multiple functions for taking photos with a 1.3Megapixel camera, surfing the Internet and listening to music," said Matt Johnson, interface product line manager at Fairchild. "As the smallest, lowest EMI, lowest power serialization device on the market, the ?SerDes solution meets the needs of the latest generation of cellphones and other ultra portable applications."

According to the press release, the FIN24AC ?SerDes solution, in a small form factor, is suited for solving the increasingly complex design challenges posed by converging product features in ultra-portable and consumer applications such as cellphones. The ?SerDes devices reduce traditionally wide parallel paths of data to a high-speed serial link, reducing the number of cables in clamshell and hinge phones and other portables to six to seven times fewer wires, the company said.

Additionally, by using Fairchild's patented Current Transfer Logic technology, ?SerDes devices are able to reduce EMI by 30dB to 40dB at the fundamental frequency while reducing troublesome harmonics to less than -100dBm, meeting the EMC standards for portable devices.

"Our customers insist on having as many different features as possible packed into an extremely thin, ultra-modern phone," said Sung-Il Ha, LG Electronics' senior engineer. "However, providing converged functionalities in a small space poses the dual challenge of diminishing unwanted noise while maximizing battery power. Fairchild's FIN24AC was integral in making our new Chocolate phones a success by answering these critical design requirements."
