TC358743XBG block diagram: HDMI to CSI-2 bridge chip

The Toshiba High Definition Multimedia Interface (HDMI) to Mobile Industry Processor Interface (MIPI®) Camera Serial Interface Type 2 (CSI-2) converter chipset, designated TC358743XBG, enables a Host processor with a MIPI CSI-2 interface to accept HDMI video and audio streams and process them as incoming data source. Application Processors can generate different types of video data for internal displays, external displays, as well as analog TV and HDMI TV; but some Application Processors have limitations in handling video data as an input source. A common input interface for video streams is MIPI CSI-2, which is a high-speed serial interface to an embedded camera. The Toshiba bridge, TC358743XBG, enables HDMI video stream to be processed by the Application Processor as a CSI-2 video stream. Audio is supported and can be transmitted over CSI-2 stream or over I 2S.

The maximum resolution supported is 1080P at a refresh rate of 60 fps. The bridge supports common 3D video formats and protocols compatible with the HDMI 1.4 standard. The TC358743XBG supports a MIPI CSI-2 interface to the Host with configurable 1, 2, 3, or 4 data lanes with lane speeds of up to 1 Gbps per lane.

The Toshiba TC358743XBG is a 64-pin device and is optimized for the portable market. It has a small package size of 6 mm x 6 mm, 0.65 mm ball pitch. It is designed with clock and power management circuitry to support low-power states.
