1. General description
The TDA9983B is an HDMI transmitter (which also supports DVI) that enables a 3 × 8-bit
RGB or YC
B
C
R
video stream (with a pixel rate up to 150 MHz for the TDA9983BHW/15
version), up to 4 I
2
S-bus audio streams (with an audio sampling rate up to 192 kHz) and
the additional information required by all the HDMI 1.2a standards.
A programmable upscaling block enables a 720p/1080i output from a standard definition
input. An intrafield deinterlacer is included in the scaler.
In order to be compatible with most applications, the TDA9983B integrates a full
programmable input formatter and color space conversion block. The video input formats
accepted are YC
B
C
R
4 : 4 : 4 (up to 3 × 8-bit), YC
B
C
R
4:2:2 semi-planar (up to
2 × 12-bit), YC
B
C
R
4 : 2 : 2 compliant with ITU656 and ITU656-like (up to 1 × 12-bit).
For ITU656-like formats, double edges are supported so that data can be sampled on
rising and falling edges.
The device can be controlled via an I
2
C-bus interface.
