Sony presents ‘Single wire interface technology’ for mobile devices
Sony has developed ‘single wire interface technology’,which allows the transmission of both data and power through a single cable (copper wire).
Currently, the mobile devices use several dozen cables for video, audio, control signals and power transmission, which make difficult for manufactures to produce mobile phones with moving or folding parts like screens, keyboards etc. With the new Sony’s single cable technology, the future devices with movable mechanisms will have improved flexibility, reliability and durability.
Sony’s ‘single wire interface technology’ has achieved bi-directional transmission by using time division duplex and multiplex method of digital data transmission using time slot, and this allowing transmission of multiple signals, including video, audio, control signals, as well the DC power on the same signal cable. Sony’s unique encoding technology with DC balance enables both DC power supply and high speed data to be transmitted within a limited frequency bandwidth.
For quick implementation of this technology, Sony has teamed up with ROHM Co., Ltd. and will grant them a license for the IP of the new technology in order to advance the development of a single chip which includes both the analog and digital portions.
