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 TFP401 and TFP401A are compliant to the DVI Specification Rev. 1.0.

2.  The TFP401/401A has an internal voltage regulator that provides the 1.8-V core power supply from the externally supplied 3.3-V supplies.

3.  The TFP401A incorporates additional circuitry to create a stable HSYNC from DVI transmitters that introduce undesirable jitter on the transmitted HSYNC signal.

Description

The Texas Instruments TFP401 and TFP401A are TI PanelBus™ flat panel display products, part of a comprehensive family of end-to-end DVI 1.0 compliant solutions. Targeted primarily at desktop LCD monitors and digital projectors, the TFP401/401A finds applications in any design requiring high-speed digital interface.

The TFP401/401A supports display resolutions up to UXGA in 24-bit true color pixel format. The TFP401/401A 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 TFP401/401A 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.
