Toshiba releases interface bridge devices for automotive infotainment applications

From Toshiba Electronics Europe comes a range of video interface bridge devices intended for modern automotive In-Vehicle Infotainment (IVI) applications.

Increasingly, Systems-on-Chip (SoCs) from smartphones and tablets have been used in automotive applications as IVI systems became more sophisticated, requiring more functionality and greater performance.

However, owing to differing connectivity standards on devices such as displays, existing SoCs can often lack the necessary interfaces required for automotive networks.

Toshiba’s latest range of video interface bridge devices provide HDMI to MIPI CSI-2 (TC9590), MIPI CSI-2 to/from parallel (TC9591) and MIPI DSI to LVDS (TC9592/3) connectivity.

The devices come in 0.65mm pitch, VFBGA packages between 5 x 5 mm and 7 x 7mm, with the exception of the TC9590 which is housed in an LFBGA64, 0.8mm pitch 7 x 7mm package.

The TC9592, with its single link, five pairs/link LVDS output is suitable for connecting SoCs to a UXGA 1600 x 1200 24-bit display.

The TC9593 provides a dual link, five pairs/link LVDS output, making it suitable for displays up to WUXGA 1920 x 1200 in size.

The TC9591 can be configured to convert 24-bit parallel data at 154 MHz to 4-lane MIPI CSI-2, or MIPI CSI-2 to 24-bit parallel data at 100 MHz.

The TC9590 supports HDMI 1.4a at its input and 4-lane MIPI CSI-2 at its output.

All the devices operate from -40 degrees C to +85 degrees C, although the TC9591XBG extends the upper limit to +105 degrees C.

Toshiba has drawn on its experience in developing MIPI-based interface bridge chips for consumer applications while developing the new automotive IVI range.

Sample shipments of the new devices start this month.
