Close Proximity Wireless Transfer Technology TransferJet™-compliant IC

TC35420 is a wireless IC product that supports the TransferJet™ standard for close proximity wireless transfer technology. The TransferJet™ Consortium has defined the standard for this technology. This IC implements TransferJet™ functions with wireless, Digital-signal-processing, Host-Interface, and memory-interface functions in a single chip using RF-CMOS process.

What is “TransferJet”?　TransferJet™ is a close proximity wireless transfer technology featuring simple operation, safe communication and efficient transfer of data.

Just touching two devices Intuitive operation: two devices are brought into physical contact so that files are transferred automatically. No need for complex setup, device pairing or the use of access points. Point-to-point connectivity with no host/target relationship. Data transfer can take place between mobile phones and stationary PCs, as well as between two mobile/handheld devices.

A short transmission distance means user can specify and restrict which other devices can be connected Short transmission distance minimizes leakage of data, without the need for difficult security measures or setup procedures. Users can register their electronic products to enable TransferJet™ to recognize and connect to specific devices only, minimizing the risk of unintended unauthorized access.

Very High-speed transfer Physical layer transmission rate is 560 Mbps, maximum data throughput is 375 Mbps. Just a few seconds needed to transfer a one-hour TV program (e.g., in MPEG4, 170 MB). Capable of adjusting the appropriate data transmission rate according to the quality of the wireless medium. Even if conditions deteriorate, TransferJet™ can maintain the highest possible wireless link by automatically adjusting the data transmission rate. As TransferJet™ is a close proximity wireless system that radiates very low-power radio waves, it causes virtually no interference to other wireless systems, and there is no impact on performance (no interference) even if multiple users simultaneously use TransferJet™ in nearby areas.
