Mobile peripheral device operates as hub or bridge

Toshiba Electronics Europe (TEE) has announced a mobile peripheral device (MPD) IC that can operate as a hub or a bridge in applications built around high-speed serial MIPI standards.

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 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).
