China has seen an explosion of growth in cell phones over the past 15 years, led primarily by the popularity of candy bar phones. This situation is now changing as the market starts exploring features and functions delivered by different form factors, such as twist phones, especially those with TV functions, gain popularity in China.

uSerDes^TM serializer/deserializer devices have been adopted by the world’s major cell phone manufacturers for multifunction cell phones designs. This technology reduces the number of parallel buses needed for data transmission in flip phones, slide phones or swivel phones, and acts as a converter between the parallel bus and serial bus, converting system signals from parallel to serial, and then converting serial signals back to parallel signals for peripherals. It also increases system reliability, delivers better EMI and ESD endurance, enhances overall system performance, and simplifies interface design, leaving structure engineers with more flexibility.

Designers have two types of uSerDes products to use in cell phone design. One is for LCD data transmission and another is for camera data transmission

uSerDes devices are a current transfer logic (CTL^TM) based data transmission technology for parallel-serial-parallel conversion, and involves small serial signal transmission at very high speed. While it was once considered complex, it is now widely accepted among design engineers. Additionally, well-established design resources offer a better understanding of the properties and functionalities of uSerDes devices and helps R&D engineers solve issues they encounter when developing applications with uSerDes technology.

China has a unique phone design market, made up of independent design houses (IDHs), and in-house R&D engineers. Both of these design areas can benefit from the added features uSerDes products offer, which is more functionality and greater customer satisfaction.

Widely recognized as an industry guru, he’s had a string of successes in the switching and multiplexing of both data and analog signals. When he’s not researching and developing innovative power and signal path ICs for portable devices he can usually be found online chatting and sharing his knowledge with his many friends and followers around the globe. He’s ‘always on’ and is fully socially networked, Twittering and Facebooking anyone who’ll listen. A regular ‘Inspector Gadget,’ Dr. Portable is rarely seen without the very latest portable device in hand, whether it’s the latest generation Smartphone, ebook, netbook or MID. A keen traveler, he is always on the go. He stays on top of his game by regularly working out and is very careful what he eats. In fact it’s probably fair to say that he’s obsessed with losing weight and getting thinner as well as smarter.
