Toshiba Electronics expands mobile peripheral device family with MIPI® display hub/bridge

When used as a hub, the TC358710XBG can multiply the number of available MIPI DSI (Display Serial Interface) ports. This simplifies, for example, the implementation of support for multiple displays. As a bridge the new device provides a link between legacy interface standards and MIPI interfaces, allowing designers to extend the lifetime of existing host and display systems.

In hub mode the TC358710XBG MPD can take a single DSI input and distribute the incoming DSI packets to up to two DSI ports and one shared DBI-B/C (Display Bus Interface Type B/C) output. When the device is set up in bridge mode it can take a parallel MIPI DBI-B from a host microcontroller and supply up to three different display devices over high-speed serial MIPI DSI links.

The TC358710XBG provides for selectable two-lane DSI or 8/16-bit DBI-B host interface support and operates with DSI link speeds up to 820MB/s per lane. An integrated DSI packet buffer accommodates packet sizes up to 4KB.

The MPD is provided in a compact 4mm x 4mm FBGA package and operates from a single 1.8V power supply. Low current operation and sleep and deep sleep options help to reduce power consumption, while the option of allocating pins from unused interfaces as GPIOs enhances design flexibility. Spread spectrum clock generation ensures low electromagnetic radiation (EMR).
