Texas Instruments has released an interface IC called SN65DSI86 that provides a MIPI DSI bridge from graphics processor to embedded DisplayPort (eDP) LCD panels. The IC supports a screen resolution of up to 4K2Kp60 for tablets, clamshell notebooks, and all-in-one PCs.

The company says the SN65DSI86's 1.5Gbit/s DSI data rate delivers more than 30 per cent higher bandwidth compared with other devices. The device's dual MIPI DSI channels in a 20 per cent smaller, 5-mm by 5-mm package that saves PCB area, allowing system designers to have more design flexibility for space-constrained mobile applications.

The SN65DSI86 works with the SN75DP130 DisplayPort re-driver, and is part of a pin-compatible family of MIPI DSI bridge chips that allow designers to select the right bridge for the resolutions they need. They are an extension of TI's FlatLink serial interface portfolio, which reduces the number of signal lines used for synchronous parallel data bus structures with no loss in data throughput. TI's display interface portfolio addresses display panels in all shapes and sizes. Flatlink interface ICs manage short-haul links for mobile devices and products with small displays, while FPD-Link SerDes chipsets support long, robust links in automobiles.

A variety of tools and support are also available to speed development with the SN65DSI86, including an IBIS model, DSI tuner software, and hardware implementation guide.

The SN65DSI86 is currently available in a 5-mm by 5-mm, 64-ball PBGA package. Suggested retail pricing is $5.61 in 1,000-unit quantities.
