Parade Technologies Ltd has released the DP606 DisplayPort mobile PC LCD timing controller at this week's Intel Developers Conference in San Francisco, California. It was specifically designed for embedded notebook display applications, where DisplayPort serves as the video transport protocol between the notebook motherboard and display panel.

The device uses a one-lane DisplayPort interface and supports up to 1680 x 1050 pixel resolution, which covers almost all mainstream notebook PC applications. Delivering low-power use, which provides long battery life for notebook PCs, Parade claims the DP606 offers the lowest power use of any available DisplayPort timing controller (TCON) device such as 180mW typical at 1440 x 900 resolution. It added that its power consumption is also lower than many existing LVDS TCON ICs, a motherboard-to-display interface technology used on the previous generation of notebook computers.

The timing controller leverages Parade's proprietary advanced equalizer and clock-data recovery technology in the DisplayPort receiver. This permits the system integrator to skip the initial link training protocol specified for external DisplayPort devices, using an instant on display capability. This simplifies power management by reducing driver overhead. The TCON receiver also has Parade's CrystalFree technology, which draws away the need for an external timing reference crystal or clock source. The device is in a 64-pin QFN (9mm x 9mm) package.
