TDA9981B

HDMI transmitter up to 150 MHz pixel rate with 3 × 8-bit video

inputs and 4 × I²S-bus with S/PDIF

Rev. 01 — 4 July 2008

Product data sheet

1. General description

The TDA9981B 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 TDA9981BHL/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.

In order to be compatible with most applications, the TDA9981B 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 TDA9981B 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

I Programmable color space converter:

N RGB to YCbCr

N YCbCr to RGB

I Controllable via I²C-bus

I Low power dissipation

I 1.8 V and 3.3 V power supplies

I Power-down mode

I Hard reset
