description
The TFP401/401A supports display resolutions up to SXGA in 24-bit true color pixel format. The TFP401/401A
offers design flexibilty 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 TM advanced packaging technology results in best of class power dissipation, footprint, and ultra-low
ground inductance.
The TFP401/401A combines PanelBus TM circuit innovation with TI’s advanced 0.18-um EPIC-5 TM CMOS
process technology, along with TI PowerPAD TM package technology to achieve a reliable, low-powered, low
noise, high-speed digital interface solution.

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.
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.
The TFP401/401A incorporates additional circuitry to create a stable HSYNC from DVI transmitters that introduce undesirable jitter
on the transmitted HSYNC signal.
