TDA9983B
HDMI transmitter up to 150 MHz pixel rate with 3 × 8-bit video
inputs and 4 × I2S-bus with S/PDIF
Rev. 01 — 20 May 2008
Product data sheet
1. General description
The TDA9983B is an HDMI transmitter (which also supports DVI) that enables a 3 × 8-bit
RGB or YCBCR video stream (with a pixel rate up to 150 MHz for the TDA9983BHW/15
version), up to 4 I2S-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 YCBCR 4 : 4 : 4 (up to 3 × 8-bit), YCBCR 4 : 2 : 2 semi-planar (up to
2 × 12-bit), YCBCR 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 I2C-bus interface.
2. Features
I 3 × 8-bit video data input bus, CMOS and LV-TTL compatible
I Horizontal synchronization, vertical synchronization and Data Enable (DE) inputs or
VREF, HREF and FREF could be used for input data synchronization
I Pixel rate clock input can be made active on one or both edges (selectable by I2C-bus)
I The TDA9983B has 4 I2S-bus audio input channels and 1 S/PDIF channel; audio
sampling rate up to 192 kHz
I 250 MHz to 1.50 GHz HDMI transmitter operation
I Programmable input formatter and upsampler/interpolator allows input of any of the
4 : 4 : 4, 4 : 2 : 2 semi-planar, 4 : 2 : 2 ITU656 and ITU656-like formats
