Toshiba Electronics has extended its family of Mobile Peripheral Devices by introducing a MIPI®-to-DisplayPort® bridge IC that simplifies integration of an embedded display and also gives end users the option to connect their handheld device to an external display.
The TC358766 bridge converts a MIPI Display Serial Interface (DSI) or Display Pixel Interface (DPI), the formats typically supported by today’s mobile application processors, into an output signal for transport via up to two DisplayPort® pairs. This enables designers of handheld products to integrate a chosen screen quickly and easily using an embedded DisplayPort® (eDP) connection, and also to provide an external DisplayPort® interface enabling end users to connect an additional display for purposes such as making presentations.
The output comprises two DisplayPort® 1.1a Main Links supporting 1.62Gbps or 2.7Gbps link rates, each with an associated 1Mbps AUX channel. If required, the two Main Links can support connection to a single, high-bandwidth display. Displays up to 1920 x 1200 (WUXGA) resolution can be connected, at 24 bits per pixel and 60 frames per second. The TC358766 integrated DSI receiver supports up to four DSI lanes with data rates up to 1Gbps per lane, for maximum total bandwidth of 4Gbps. The DPI receiver supports parallel interfaces of up to 24 bits and can be operated at parallel clock speed up to 154MHz.
Further connectivity includes an I2S interface, giving designers the option to stream audio via I2S or through the DisplayPort® link according to application requirements. In addition, one I2C slave interface and one SPI 30MHz interface are provided for debugging and for accessing the chip registers. The device also supports HDCP encryption Version 1.3 with DisplayPort® amendment Revision 1.1.
The TC358766 is available in a 6.0mm x 6.0mm, 1.0mm-high 120-pin BGA package.
