IC supports screen resolutions up to 4K2K

4th December 2013


Texas Instruments (TI) has introduced a new interface IC that provides a MIPI DSI bridge between the graphics processor and embedded DisplayPort (eDP) panel. It supports the industry’s highest screen resolution up to 4K2Kp60 for tablets, clamshell notebooks and all-in-one PCs.

Compared with competitive devices, the SN65DSI86’s 1.5-Gbps DSI data rate delivers more than 30 per cent higher bandwidth. In addition, its dual MIPI DSI channels in a 20 per cent smaller, 5mm by 5mm package saves PCB area, providing system designers greater design flexibility for space-constrained mobile applications.

Key features and benefits of the SN65DSI86:

* Optimised MIPI DSI bridge to eDP: Supports LCD panels up to 4096 by 2160p with 18 bits per pixel (bpp) at 60 frames per second (fps), and 1920 by 1200 WXUGA 3D resolution (24bpp) at 120fps with odd/even or left/right configurations. This gives system designers the flexibility to support a variety of different panels and resolutions.

* Higher DSI frequency/bandwidth: Dual-channel, four MIPI DSI lanes support 1.5 Gbps, offering a maximum input bandwidth of 12Gbps for the highest data throughput performance compared to competitive solutions. Compatibility with eDP version 1.4 supports seven data rates up to 5.4Gbps HBR2, which allows system designers to use fewer wire and board traces between the device and LCD panel.

* Ultra-low power: Power consumption of less than 200mW active, 30mW suspend power and 3mW shutdown extends system battery life.

* Advanced signal conditioning: Combination of receive equalisation, selectable transmitter de-emphasis and output swing enables flexible component location, and allows for longer traces between the graphics processor and SN65DSI86, as well as longer cables from the bridge chip to LCD panel.
