The Texas Instruments TFP401A is a TI PanelBus™ flat panel display product, 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 finds applications in any design requiring high-speed digital interface. The TFP401A supports display resolutions up to 1080p and WUXGA in 24-bit true color pixel format. The TFP401A 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 ultra-low ground inductance. The TFP401A combines PanelBus™ circuit innovation with TIs advanced 0.18-mm EPIC-5™ CMOS process technology, along with TI PowerPAD™ package technology to achieve a reliable, low-powered, low-noise, high-speed digital interface solution.
(1) The Digital Visual Interface Specification, DVI, is an industry standard developed by the Digital Display Working Group (DDWG) for high-speed digital connection to digital displays. The TFP401A is compliant to the DVI Specification Rev. 1.0.
(2) The TFP401A has an internal voltage regulator that provides the 1.8-V core power supply from the externally supplied 3.3-V supplies.
(3) Immunity The TFP401A incorporates additional circuitry to create a stable HSYNC from DVI transmitters that introduce undesirable jitter on the transmitted HSYNC signal.
