TDA9984BHW HDMI 1.4a transmitter with 1080p upscaler embedded

The TDA9984A; TDA9984B is a High-Definition Multimedia Interface (HDMI) 1.4a transmitter with embedded 1080p upscaling functionality. It is backward compatible DVI 1.0 and can be connected to any DVI 1.0 and HDMI sink. It allows mixing a 3 x 8-bit RGB or YCbCr video stream with a pixel rate up to 150 MHz together with up to 4 × I2S-bus or one S/PDIF audio streams with an audio sampling rate up to 192 kHz. It supports Gamut boundary description (xvYCC), as well as HD audio, both HDMI 1.4a features. A programmable upscaling block allows creating a 1080p output from a standard definition input. An intrafield deinterlacer is included in the scaler.

In order to be compatible with most applications, and thanks to the integration of a fully programmable input formatter and color space conversion block, the video input formats accepted also include YCbCr 4 : 4 : 4 (up to 3 × 8-bit), YCbCr 4 : 2 : 2 semi-planar (up to 2 × 12-bit) and YCbCr 4 : 2 : 2 compliant with ITU656 (up to 1 x 12-bit). In case of ITU656-like format, the input pixel clock can be made active on both edges. TDA9984A; TDA9984B supports xvYCC HDMI 1.4 feature and new HDMI 1.4a 3D formats. The HDCP key set can be stored internally in a non-volatile OTP memory for maximum security only in TDA9984A.

The TDA9984A; TDA9984B includes a true I²C-bus master interface for DDC-bus communication for EDID purpose.

The TDA9984A; TDA9984B can be controlled by an I²C-bus interface
