description
The Texas Instruments TFP6422 and TFP6424 are PanelBus flat panel display products, part of a
comprehensive family of end-to-end DVI 1.0 compliant solutions. Targeted primarily at digital entertainment /
set-top-box applications, Internet PCs/appliances, PC-to-TV, and connectivity to DVD players and digital
camcorders/cameras, the TFP6422/6424 finds applications in any design requiring a high-speed digital
interface combined with TV-out support.
The scalable (1.1 V to 1.8 V) low-swing digital pixel interface provides a low-EMI and high-speed bus that
connects seamlessly with Intels Digital Video Out (DVO) port, perfectly linking the graphics controller and the
DVI transmitter. The DVI interface supports display resolutions up to UXGA at 165 MHz in 24-bit true color pixel
format.
The TFP6422/6424 combines a high performance DVI transmitter and a high performance NTSC/PAL video
encoder into a single chip in a compact 64-pin TQFP package, providing a cost–effective video output solution
for the most demanding multimedia applications. The video encoder provides advanced horizontal and vertical
scaling for overscan compensation and features a 5-tap adaptive anti–flicker filter. These features combine to
produce high quality display of noninterlaced data on traditional interlaced TV.
The TFP6422/6424 combines PanelBus circuit innovation with TIs advanced 0.18 µm EPIC-5 CMOS
process technology along with TI PowerPAD ultra-low ground inductance package technology to provide a
reliable, low-powered, low noise solution with integrated high-speed digital interface and highest quality TV
output.

1. The Digital Visual Interface (DVI) specification is an industry standard developed by the Digital Display Working Group (DDWG) for
high–speed digital connection to digital displays. The TFP6422 and TFP6424 are compliant to the DVI Specification Rev. 1.0. Both are also
compliant to the SMPTE 170M NTSC composite video, and CCIR624/CCIR601 PAL composite video specifications.
2. Programmable functionality includes: arbitrary horizontal and vertical downscaling ratio, sync, black and blank levels, color burst amplitude,
luminance and chrominance gains, luminance delay, subcarrier frequency, overscan compensation, flicker removal and SCH.
