The TFP401PZPG4 is an integrated high-definition multimedia interface (HDMI) receiver and transmitter from Texas Instruments. It is a single-chip solution that supports HDMI 1.4b and HDCP 1.4 between a source and a sink. This device is capable of operation at both the receiver and transmitter channel. It incorporates a high-performance back-end system with integrated HDMI receiver and transmitter, HDMI repeater, and HDCP encryption/decryption.

The TFP401PZPG4 integrates four video and one audio ports with separate PLLs supporting both input and output ports. Each channel has an independent interface clock, and the I/O is programmable either to support HDMI 1.4b or HDCP 1.4. This single-chip solution supports a wide range of resolutions, up to 1080p. Additionally, the receiver can handle up to 10-bit data, driving up to 150 MHz of pixel clock rate. It also supports EDID handshaking and allows the sink to monitor any incoming data from the source.

The TFP401PZPG4 is suitable for applications in any field where HDMI is being used, including but not limited to home theater systems, monitors, and displays, as well as for industrial applications such as automotive displays, medical imaging, and gaming consoles. It is a highly versatile device that offers excellent performance, flexibility, and compatibility.

Working Principle of TFP401PZPG4

The TFP401PZPG4 supports both HDMI 1.4b and HDCP 1.4. It acts as both a receiver and a transmitter, allowing it to send and receive signals from either a source or a sink. The receiver portion handles input signals, allowing them to be received and decoded before the signal is passed to the transmitter for output to the sink. The TFP401PZPG4 also handles both audio and video data, allowing for a single-chip solution.

The receiver can handle up to 10-bit of data, driving a substantial pixel clock rate of up to 150 MHz. It also supports EDID handshaking and synchronizes the video, audio, and data signals before sending the decoded output to the transmitter. The TFP401PZPG4 has independent video and audio paths, with independent PLLs that support both input and output ports.

When transmitting, the TFP401PZPG4 supports up to 100 MHz of pixel clock, allowing for resolutions up to 1080p. The integrated HDCP encoder encrypts signals for output, allowing for secure transmission of data. Additionally, the integrated HDMI repeater ensures reliable transmission and reception of data over long distances. The TFP401PZPG4 also supports RGB and YCrCb color space formats.

Conclusion

The TFP401PZPG4 is an excellent solution for applications requiring a single-chip integrated HDMI receiver and transmitter. It offers excellent performance, flexibility, and compatibility. This device can be used in a wide range of applications including home theater systems, industrial displays, medical imaging, and gaming consoles. It is capable of handling up to 10-bit data, driving up to 150 MHz of pixel clock rate. Furthermore, the integrated HDCP encoder allows for secure data transmission between source and sink. This single-chip solution offers tremendous benefit over previous solutions, offering seamless, high-definition video and audio content.
