PanelBus DVI Receiver 165MHz, HSYNC fix


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 and TFP401A supports display resolutions up to 1080p and WUXGA 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 ultralow ground inductance.

The TFP401 and TFP401A 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.

(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 TPF401 and TFP401A are compliant with 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 external 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.
