Automotive Catalog PanelBus ™ DVI Receiver 165MHz, HSYNC fix

Automotive Catalog PanelBus ™ DVI Receiver 165MHz, HSYNC fix - TFP401A-Q1


The Texas Instruments TFP401A-Q1 device is a TI Panelbus™ flat-panel display product, and is part of a comprehensive family of end-to-end DVI 1.0-compliant solutions. Targeted primarily at desktop LCD monitors and digital projectors, the TFP401A-Q1 device finds applications in any design requiring high-speed digital interface.

The TFP401A-Q1 device supports display resolutions up to 1080p and WUXGA in 24-bit true-color pixel format. It also offers design flexibility to drive one or two pixels per clock, supports TFT or DSTN panels, and provides an option for time-staggered pixel outputs for reduced ground bounce.

PowerPAD advanced packaging technology results in best-of-class power dissipation, footprint, and ultralow ground inductance.

The TFP401A-Q1 combines Panelbus circuit innovation with TI’s advanced 0.18-µm EPIC-5™ CMOS process technology, along with TI PowerPAD package technology to achieve a reliable, low-powered, low-noise, high-speed digital interface solution.
