System-on-chip devices (SoCs) for smartphones and tablets are also increasingly being used in automotive applications, as IVI systems become increasingly powerful and offer more functions. However, due to the different data connection standards for devices such as displays, existing SoCs often lack the necessary interfaces for automotive networks.

Toshiba’s new video interface bridge ICs support the following connections: HDMI to MIPI CSI-2 (TC9590), MIPI CSI-2 to/from parallel (TC9591) and MIPI DSI to LVDS (TC9592/3). The devices are offered in VFBGA packages with 0.65mm pitch and sizes between 5 x 5mm and 7 x 7mm – with the exception of the TC9590, which is housed in a 7 x 7mm LFBGA64 package with 0.8mm pitch.

The TC9592 with its single-link, 5 pair/link LVDS output is suitable for connecting SoCs to a UXGA 1600 x 1200 24-bit display. The TC9593 offers a dual-link, 5 pair/link LVDS output and is therefore ideal for displays up to WUXGA 1920 x 1200.

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 the input and 4-lane MIPI CSI-2 at the output.

All devices operate in the temperature range from -40 to +85°C; the TC9591XBG even offers an upper temperature limit of +105°C.

Samples of the new bridge ICs will be available from June 2018.
