Texas Instruments TFP501/TFP403 Reference Design Application notes
Application Note
SLLA134 – March 2003
TFP501, TFP403 Reference Design
Digital Visual Interface
TEXAS INSTRUMENTS TFP501
The TFP501 is a DVI 1.0 compliant 165-MHz receiver incorporating HDCP(High-bandwidth
Digital Content Protection) that provides a secure digital connection between a DVI transmitter
and DVI receiver. For more information on the HDCP specification, please refer to the DDWG
specification of HDCP which can be found at http://www.digital-cp.com/.
TEXAS INSTRUMENTS TFP403
The TFP403 is DVI 1.0 compliant 165-MHz receiver which is pin to pin compatible with the
TFP501, all functions are identical to the TFP501 with the exception of HDCP functionality. The
TFP403 can be designed into an existing system to be replaced with a TFP501 when HDCP is
required with no board layout changes needed.
When using the TFP403, some board components are not necessary for the functionality of the
device, such as the EEPROM. The components highlighted in RED on the following page reflect
those components.
Optional Components for TFP403:
4 – 10-kOhm pull-up resistors on pins 92, 93, 95, 96 of TFP403.
1 – Serial EEPROM (ATMEL AT24C04).
1 – 4.7-uF Capacitor on pin 8 of EEPROM.
2 – N-channel MOSFET(Philips BSN20)
This document is to be used as a reference guide only. Please refer to the TFP501 and TFP403 data sheets for
individual pin functions. Optional Components for TFP403.
