    The resolution and the image/video quality of the multimedia content is getting improved by each passing day. This off course means larger file sizes and huge data transfer between multimedia devices. Specialized integrated circuits are required to keep up with the faster data transfer protocols such as HDMI, MIPI, and LVDS. These devices are known as bridges which are used as an interface between processors and peripherals with different interfaces. Toshiba is a leading manufacturer of such bridging devices used extensively in image/video systems.

    What is TC358743XBG?

    The TC358743XBG is a bridge device manufactured by Toshiba which converts HDMI-RX stream into MIPI CSI-2 TX. The current and the next generation of baseband ICs and application processors do not have a dedicated video streaming input port. These processors and ICs only incorporate a CSI-2 port for camera input. However, due to large number of smart phone device in existence, the smart phone processors often require video input. This solution for the absence of a dedicated video port on the processor is offered by TC358743XBG. This IC takes HDMI video as input and converts it to CSI-2 format which can then be fed to the smart phone processor.

    How TC358743XBG work?

    The current generation and the next generation of application processors and broadband ICs in the smart phones do not have a dedicated HDMI video streaming port. These processors only feature a CSI-2 port for camcorder/camera input. To cope with this problem, bridge ICs are used. The bridge IC converts the HDMI video into CSI-2 format which acceptable to the smart phone processor.
