• Built-in audio decoder capable of processing Dolby Digital Plus and DTS-HD streams
• Supports high-definition video resolutions up to 4Kx2K at 30Hz
• Includes integrated PLL for pixel clock generation up to 340MHz

Video Processing Applications

• High-definition televisions and monitors
• Set-top boxes and media streaming devices
• Blu-ray players and home theater systems
• Professional AV display equipment

Video Processing Procurement Notes

Verify the specific suffix C1,518 against official NXP documentation to confirm tape-and-reel packaging and temperature grade. Confirm RoHS compliance status via the latest environmental declaration. Check for active production status or last-time-buy notices as HDMI transmitters are frequently updated. Ensure pinout compatibility with existing PCB layouts before procurement.

Video Processing Selection Notes

Select this component when HDMI v1.4 compliance and integrated audio decoding are required in a single chip solution. It is suitable for designs needing HDCP 1.4 protection without external crypto controllers. Consider the 64-pin LQFP package size for board space constraints. Verify that the 340MHz pixel clock limit meets the target resolution requirements.

Video Processing Part Context

This part belongs to the TDA19971 family of HDMI transmitters designed for consumer electronics. It serves as a bridge between source processors and display panels. The series is optimized for low power consumption and high signal integrity in compact form factors common in modern AV devices.

Video Processing Replacement Considerations

Check NXP datasheets for direct pin-to-pin compatible upgrades such as later revisions of the TDA19971 series. Verify if newer HDMI versions (e.g., v2.0/2.1) require different components like the TDA19988 or TDA19989 for higher bandwidth needs.
