TC35420 is a wireless IC product that supports the TransferJet™ standard for high-speed, close proximity wireless transfer 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. The TransferJet™ Consortium has defined the standard for this technology.

The company Icoteq offers an IMX6 based development board with integrated TransferJet™ module for application development. Icoteq offers Linux based drivers and application notes.
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.
A TransferJet system consists of a coupler and a transceiver IC. Unlike conventional antennas, the TransferJet coupler is designed to reduce far-field electric field components and amplify close electric field signals.
The following describes a small TransferJet coupler for microSD card applications realized using PCB traces.
Measuring only roughly 12 mm by 2 mm, this TransferJet coupler can be etched onto small boards such as microSD cards.
The following figures show that the electric fields over both the X-Y and X-Z planes are properly coupled to the TransferJet coupler.
Since TransferJet™ is simple, safe, fast and stable, it is finding increasingly widespread use in various applications such as home, office, mobile and automotive appliances.
