Fairchild Semiconductor announces that its FIN24AC µSerDes has been selected for use in LG Electronics' new "Chocolate" phones, the first series of LG's Black Label cellphones. The FIN24AC was chosen for its ability to ease design complexity, reduce size, lower EMI and save battery-power in LG's extremely sleek, multi-functional cellphone designs, Fairchild said.

The FIN24AC µSerDes 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 cell phones. The µSerDes 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, µSerDes 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. Also, standby power consumption is ten times lower with the µSerDes than with any other solution.

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

"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 Chocolate phones a success by answering these critical design requirements."
