TDA19972BEL Dual input HDMI 1.4b receiver with equalizer

The TDA19972 HDMI receiver proposes two HDMI inputs and standard video bus output optimized for STB and PVR system integration.

The TDA19972 offers High Definition (HD) video resolutions up to 1080p50/60 or WUXGA and HD audio formats up to 8 channels such as DTS HD and Dolby True HD while keeping advanced sleep modes power management.

This chip optionally includes HDCP 1.4 engine with pre-programmed keys stored into an internal non-volatile memory to provide highly secured solution and simplify manufacturing process.

This chip features several HDMI 1.4b options such as 3D format up to 1080p50/60, Deep Colors up to 36 bits per pixel and extended colorimetry. The TDA19972 integrates 8 kV system ESD protections and non-volatile memory for EDID storage to minimize BOM.

An optimized auto-adaptative equalizer increases TDA19972 robustness to reduced quality signals. The TDA19972 is delivered with software drivers for Linux, Windows and RTOS easy to implement and to configure.

To build a complete system with the TDA19972, refer to the corresponding application notes. Evaluation platforms and user guide are available on request to NXP support
