It is a given that users hope for 4K ultra high definition (UHD) experience when watching videos on tablets or phablets, or running their favourite role-playing game on their portable gaming systems. Toshiba America Electronic Components, Inc. (TAEC) has stepped forward with a solution that, while enabling 4K resolution, allows displays to operate at low power.

The TC358860XBG, an embedded DisplayPort (eDP)-to-MIPI dual-display serial interface converter chipset, incorporates both video format conversion and compression technology to support 4K2K high-resolution displays. Employing both high-speed serial interface industry standards with low power operation capability in a single chip enables UHD 4K displays while maintaining handhelds' low power consumption requirements. The chipset also delivers the high refresh rates, beyond 60fps, needed to enable a "living room" quality gaming experience in a handheld gaming system.

The chipset provides eDP incoming data support for VESA eDP v1.4. This includes eight types of bitrate support ranging from 1.62Gbit/s to 5.4Gbit/s, maximum 1Mbit/s AUX channel support, and native and I2C-over-AUX transaction support. On the outgoing data side, the chipset supports MIPI dual-port DSI with maximum 1Gbit/s per lane link speed interface and a total data transfer capability of 8Gbit/s.

Housed in a 5.0mm x 5.0mm FBGA65 package with 0.5mm ball pitch, the device is available for sampling, with mass production scheduled for March 2015.
