TDA9984A

HDMI 1.3 transmitter with 1080p upscaler embedded

Rev. 04 — 15 January 2009

Product data sheet

1. General description

The TDA9984A is a High-Deﬁnition Multimedia Interface (HDMI) v. 1.3 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 × 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 1.3 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 × 12-bit). In case of

ITU656-like format, the input pixel clock can be made active on both edges.

The TDA9984A includes a HDCP 1.2 compliant cipher block. The HDCP key are stored

internally in a non-volatile OTP memory for maximum security.

The TDA9984A includes a true I²C-bus master interface for DDC-bus communication for

EDID purpose and HDCP purpose.

The TDA9984A can be controlled by an I²C-bus interface.

2. Features

I 3 × 8-bit video data input buses; CMOS and LV-TTL compatible

I Horizontal synchronization, vertical synchronization and data enable inputs or VREF,

HREF and FREF inputs which can be used for synchronization

I Pixel rate clock input can be made active on one or both edges; selectable via I²C-bus

I 4 × I²S-bus audio input channels, one S/PDIF channel; audio data rate up to 192 kHz

per input for both standards

I Dolby-True HD and DTS-HD High bit rate audio support through the use of the HBR

interface

I 250 MHz to 1.50 GHz TMDS transmitter operation

I Programmable input formatter and upsampler/interpolator allows input of any of the

4 : 4 : 4 or 4 : 2 : 2 semi-planar and 4 : 2 : 2 ITU656-like formats
