NXP Semiconductors introduces the NXP SAA8510a mobile multimedia TV-out processor to enable TV-output on any mobile device having a standard LCD interface. The NXP SAA8510 converts mobile digital video signals into high-quality analog TV signals, which can then be displayed on any NTSC and PAL TV set, explains the company.

"As the cellphone continues to become known as the world's 'third screen' behind the TV and PC, consumers will need the added flexibility to access their mobile content beyond the two inch screens of most mobile devices," said Vincent Pronk, multimedia marketing manager, business unit mobile and personal, NXP Semiconductors. "We developed the SAA8510 TV-out processor in close collaboration with our key customers to help fuel the convergence of mobile and home multimedia, and to give end-users the freedom to take their mobile content from the small screen to the big screen whenever they want."

Although mobile picture quality is still generally low resolution, NXP explains that its TV-out processor enables mobile images to be displayed on larger TV screens with exceptional vibrancy and clarity. This high-quality output is enabled by a polyphase up/down scaler that allows different scale factors horizontally and vertically. Chrominance and luminance filters limit dot crawl effects and tearing effects are managed using a dedicated tearing effect signal. Supported input formats are RGB888, RGB666, RGB565, YUV422 and YUV420 for resolutions from 40 x 40 pixels to VGA (including WQVGA).

Touting a unique design, the SAA8510 is offered in the smallest package available on the market, claims NXP. In addition, it requires no specific clock or voltage supplies and can be addressed as a simple RAM-based display controller with no real-time constraints on the host device for easy integration by mobile device OEMs. To minimize power drain, the SAA8510 supports advanced power management functionality with embedded voltage regulators to generate all required internal voltage levels, cable plug/unplug detection and five different power modes, including low-leakage sleep mode.
