Our sales will reply to
your request by email within 24 hours.
1. You'll receive an order information email in your inbox.
(Please remember to check the spam folder if you didn't hear from us).
2. Since inventories and prices may fluctuate to some
extent, the sales manager is going to reconfirm the order and let you know if there
are any updates.
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The basic freight (for package ≤0.5kg or corresponding volume) depends on the time
zone and country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:
FedEx International, 5-7 business days.

Features for the TFP401A
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.
Description for the TFP401A
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 and TFP401A 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.
