Product details
Overview
TFP513PAP from Texas Instruments is a DVI 1.0-compliant digital transmitter IC that encodes and serializes RGB pixel data for transmission over TMDS differential links. It supports VGA-to-UXGA resolutions (25–165 MHz pixel rates), operates on a single 3.3-V supply, integrates embedded HDCP keys, and features dual-edge/24-bit input modes with adjustable 1.1–1.8-V or standard 3.3-V CMOS signal levels - used in PC graphics cards and flat-panel display interfaces.
For engineers reviewing the TFP513PAP datasheet, TFP513PAP pinout, TFP513PAP application, or TFP513PAP equivalent, key selection considerations include TMDS output skew tolerance (≤1.2 ns inter-pair), programmable I²C configuration, hot-plug detection capability, and compatibility with Intel 81x chipset digital video ports.
Technical Context
The TFP513PAP implements a full TMDS encoder with three differential output channels (TX0±, TX1±, TX2±) and a differential clock channel (TXC±), supporting both active-video (RGB) and blanking-interval (HSYNC/VSYNC/CTL) encoding. Its universal graphics controller interface accepts 12-bit dual-edge or 24-bit single-edge pixel buses with configurable VREF-based input voltage thresholds.
It integrates an on-chip PLL with enhanced noise immunity via internal regulators and bypass capacitors, delivers ≤150 ps output clock jitter, and provides data de-skew trimming (350 ps increments) to compensate for input timing misalignment between IDCK± and pixel/control signals.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar DVI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiI164 | Pin-compatible but lacks embedded HDCP keys; requires external EEPROM for key storage and license procurement. | Suitable for non-HDCP systems or where key management is handled externally; higher BOM cost and security overhead. | Choose SiI164 only if HDCP is not required or customer manages key provisioning independently. |
| TFP514PAP | Successor with identical pinout and enhanced jitter performance (≤100 ps); supports same resolutions and HDCP 1.0. | Drop-in upgrade path for new designs seeking improved signal integrity; not recommended for legacy qualification-critical programs. | Prefer TFP514PAP for new designs requiring tighter timing margins; verify HDCP key compatibility with existing firmware. |
Compared with SiI164, TFP513PAP reduces system cost and security complexity via embedded HDCP keys; compared with TFP514PAP, it offers proven field reliability at slightly relaxed jitter specs - making it optimal for cost-sensitive, volume-manufactured DVI endpoints.

FAQ
What is the primary function of the TFP513PAP in a DVI system?
The TFP513PAP serves as a DVI 1.0-compliant digital transmitter that converts parallel RGB pixel data and sync signals into serialized TMDS differential streams for transmission over twisted-pair cables. It performs TMDS encoding, HDCP encryption, and drives four differential output channels (three data, one clock), enabling resolutions up to UXGA at 165 MHz. The TFP513PAP is essential for establishing secure, high-bandwidth digital video links in PC graphics and display systems.
Does the TFP513PAP require external HDCP key storage?
No, the TFP513PAP includes embedded preprogrammed HDCP keys with on-chip encryption, eliminating the need for external EEPROM or flash memory. This integration removes the requirement for customers to procure HDCP licenses separately or implement key management firmware. The TFP513PAP handles key decryption and cipher operations internally, meeting HDCP Revision 1.0 compliance without external components.
How does the TFP513PAP support different graphics controller interfaces?
The TFP513PAP supports both 12-bit dual-edge and 24-bit single-edge input modes via pin-strapping (BSEL) or I²C configuration. It accepts adjustable 1.1–1.8 V or standard 3.3 V CMOS signal levels using the VREF pin, and supports fully differential or single-ended clock inputs (IDCK±). This universal interface enables direct connection to Intel 81x chipsets and other GPU platforms without level shifters or clock buffers - a core capability of the TFP513PAP.
What package type and thermal features does the TFP513PAP use?
The TFP513PAP is packaged in a 64-pin TQFP with TI's PowerPAD™ structure, which incorporates an exposed thermal pad on the underside of the package. This design enhances heat dissipation from the high-speed TMDS drivers and PLL circuitry, improving reliability under sustained 165 MHz operation. The PowerPAD™ requires soldering to a large copper pour on the PCB for optimal thermal performance - a defining mechanical feature of the TFP513PAP.
Can the TFP513PAP be used in hot-plug detection applications?
Yes, the TFP513PAP supports hot-plug detection through the EDGE/HTPLG pin when the I²C interface is enabled (ISEL = high). In this mode, the pin monitors the DVI receiver's hot-plug signal per VESA P&D and DFP standards, requiring only a 1-kΩ series resistor. It also provides monitor sense (MSEN) output to indicate powered-on receiver presence - both functions are integral to the TFP513PAP's role in dynamic display enumeration and power-aware systems.
