Product Brief
TC358743 Camera Serial Interface
Converter Chipset (HDMI to MIPI®)
Highlights
R
• HDMI video and audio streams into MIPI○ CSI-2 data to enable Application Processors with MIPI CSI-2
interface to process HDMI as input stream.
• Solutions are based on the latest versions of industry standards for HDMI 1.4 and MIPI CSI-2 1.01 interfaces.
• Support for common 3D formats and compatible protocols with the HDMI 1.4 standard
• Support for 1080P resolution at refresh rates of 60 fps.
• Applicable to products such as smart TVs, set-top boxes, and DVRs (digital video recorders)
Description
The Toshiba High Definition Multimedia Interface
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.
R
(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,
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 lowpower states.
Features
HDMI-RX Interface
• HDMI 1.4
– Video Formats Support (Up to 1080P)
• RGB, YUV444: 24-bpp@60 fps
• YUV422 24-bpp @60 fps
– Audio Supports
• Internal Audio PLL to track N/CTS value transmitted by
the ACR packet
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 I2S.
– 3D support
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
– Support for HDCP (High-bandwidth Digital Content
Protection)
– Support for DDC (Display Data Channel)
