Sony Unveils the World’s First TransferJet compatible LSIs
TransferJet is yet another wireless data transfer technology which allows two compatible devices to communicate by simply bringing them together to a close approximaty.The technology specification set the data transmission rate at 560 Mbps while eliminating major obstacles such as complex initial setup, unstable transmission or the need for access points. Through utilization of this technology the user for example would be able to display a picture by simply touching a digital camera to a TV, or transferring music files by just holding a cellular phone over a portable audio player.The TransferJet is expected to be used widely as a high speed universal interface connection for a variety of consumer electronic products. The specification of the TransferJet is being decided by TransferJet Consortium which was established on July 1st, 2008 ensuring interoperability between TransferJet products as well as aiming to develop and promote products and services applying TransferJet technology. As of November 30, 2009, the consortium consists of 19 promoters and 22 adopters, which Sony is a member of and holds the Administrative position. The two LSIs namely the “CXD3267AGG” and “CXD3268AGW” which Sony is introducing incorporate the wireless function, signal processing function and host interface which are required for high speed communication all in a single package using CMOS processing , which enables TransferJet functionality to be incorporated with the addition of just a few external parts which would simplify its use in small sized products. The LSIs operate at 4.48GHz frequency spectrum with a direct sequence spread spectrum modulation. Among other features, are the error correction encoder and decoder, LNA and VCO/PLL, power management function, general port output (LED control, etc) . The products are available for shipping at a sample price of 1,500 yen.

[...] Sony has developed and promoting TransferJet as a short range and high speed wireless transfer technology. The TransferJet system uses a coupler, a transmitting/receiving antenna based on inductive electric wave, instead of an ordinary antenna using the radiated electromagnetic wave, providing advantages of high speeds wireless transfer capability comparable to UWB (Ultra Wide Band) system, along with simplicity of the NFC (Near-Field Communication ) system which has been adopted by Felica, enabling user to transfer data at a rate of up to 560 Mbps by simply bringing two devices with mounted couplers within 3 cm of each other. Based on this technology, Hitachi Cable has developed a compact coupler in compliance with TransferJet technology. The compact coupler by Hitachi Cable consists of a radiating element capable of transmitting/receiving radio waves and a thin coaxial cable that supplies power to the radiated element. The coupler is designed to be used in mobile equipment. Making the coupler small to fit into the mobile equipment, reduces the size of the radiating element results in narrowing the frequency band which will in turn reduces the antenna sensitivity. However, based on company’s proprietary design technologies, the ideal shape of the radiating element can be determined ,resulting in performance at 4.20 to 4.76 GHz which is required for data transfer of up to 560 Mbps , while achieving the short range wireless data transfers within 3 cm, plus reducing the coupler’s thickness to 1.6mm. The radiating element in this product can be made from standard components such as double-layer printed circuit board, resulting in easy mass production of the coupler at a low cost. Hitachi Cable is planning for the mass production of the new coupler in March of 2010. source Share and Enjoy: [...]
