Chipset converts 4K HDMI to MIPI CSI-2

Julien Happich -March 26, 2014

Toshiba Electronics's TC358840 Ultra HD HDMI to MIPI CSI-2 converter chipset supports 4K video resolution for next-generation CE video applications including 4K (3840x2160) resolution TVs, monitors, set-top boxes, and digital media adapters.

The chipset features a 297 MHz HDMI receiver (Rx) and dual MIPI CSI-2 interface to support a maximum resolution of 4096 x 2160 at 24 bpp at a refresh rate of 24 fps or 3840 x 2160 at 24 bpp at a refresh rate of 30 fps, limited by a maximum 297-MHz HDMI bandwidth.

HDMI audio input stream is also supported and can be transmitted over I2S, TDM, or the MIPI SLIMbus (Serial Low-power Inter-chip Media Bus).

The manufacturer claims to be the first company to offer a chipset that can convert an Ultra HD HDMI video stream to a dual CSI-2 video interface on an application processor for use in 4K capable monitors. The ability of the TC358840 to make the Ultra HD HDMI interface look like a camera interface extends the reach of the smartphone processor and opens up next-generation 4K opportunities for manufacturers to pursue. The TC358840XBG is an 80-pin device developed in a 7.0 x 7.0-mm package.
