TFP401A (ACTIVE)

PanelBus DVI Receiver 165MHz, HSYNC fix

Description

The Texas Instruments TFP401 and TFP401A are TI 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 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 TFP401/401A combines 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.

Features

  • Supports Pixel Rates Up to 165 MHz (Including 1080p and WUXGA at 60 Hz)
  • Digital Visual Interface (DVI) Specification Compliant(1)
  • True-Color, 24-Bit/Pixel, 16.7M Colors at 1 or 2 Pixels per Clock
  • Laser Trimmed Internal Termination Resistors for Optimum Fixed Impedance
    Matching
  • Skew Tolerant Up to One Pixel-Clock Cycle
  • 4× Oversampling
  • Reduced Power Consumption – 1.8-V Core Operation With 3.3-V I/Os and Supplies(2)
  • Reduced Ground Bounce Using Time-Staggered Pixel Outputs
  • Low Noise and Good Power Dissipation Using TI PowerPAD Packaging
  • Advanced Technology Using TI 0.18-µm EPIC-5 CMOS Process
  • TFP401A Incorporates HSYNC Jitter Immunity(3)

(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.
