Product data sheet

1. General description

The TDA9989 is a very low power and very small size High-Definition Multimedia Interface

(HDMI) 1.3a transmitter. It is backward compatible DVI 1.0 and can be connected to any

DVI 1.0 and HDMI sink.

This device is primarily intended for mobile applications like Digital Video Camera (DVC),

Digital Still Camera (DSC), Portable Multimedia Player (PMP), Mobile Phone and Ultra

Mobile Personal Computer (UM PC) where size and very low power are mandatory for

battery autonomy.

It allows mixing 3 × 8-bit RGB or YCbCr video stream with a pixel rate up to 150 MHz

together with one S/PDIF or one I2S-bus audio streams with an audio sampling rate up to

192 kHz.

In order to be compatible with most applications, the TDA9989 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)

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 one (SDR mode) or both edges (DDR

mode).

This device provides additional embedded feature like CEC (Consumer Electronic

Control). CEC is a single bidirectional wire that transmits CEC commands (like Standby

from remote control) over the home appliance network connected through this wire. This

eliminates the need of any additional device to handle this feature thus improving BOM

(Bill Of Materials) of the whole system and enable the connected devices (CEC enabled)

to be controlled by only one remote control.

The TDA9989 supports xvYCC HDMI 1.3a feature.

It can be switched to very low power Standby or Sleep modes to save power when HDMI

is not used.

The TDA9989 includes a true I2C-bus master interface for DDC-bus communication for

EDID reading.

This device can be controlled or configured via I2C-bus interface.
