Pin Type[1] Description

D5

P core digital supply voltage[2]

B7,

G digital ground supply voltage, is used for digital core; I/O and

C4, C5

CEC oscillator

D6, D7 G analog ground supply voltage, is used for PLL; serializer,

transmitter, and parallel-to-serial shift register

[1] P = power supply, G = ground, I = input, O = output.

[2] To support 1080p video format, the 1.2 V supply voltage must be raised to 1.8 V.

7. Functional description

The TDA9989 is designed to convert digital data (video and audio) provided by Set-Top

Boxes (STB), Digital Video Camera (DVC), Digital Still Camera (DSC), Portable

Multimedia Player (PMP) or DVD into an HDMI output, which can be used by a TV with

either an HDMI or DVI input.

The TDA9989 is able to output HDMI with the formats:

• RGB 4 : 4 : 4

• YCbCr 4 : 4 : 4

• YCbCr 4 : 2 : 2

The video data input formats are:

• RGB 4 : 4 : 4

• YCbCr 4 : 4 : 4

• YCbCr 4 : 2 : 2 semi-planar

• YCbCr 4 : 2 : 2 ITU656-like

It can also handle audio formats:

• two I2S-bus channels

• one S/PDIF channel (Dolby Digital: 5.1 CH, DTS, AC3)

The TDA9989 is also designed to support CEC protocol. For more details about CEC,

refer to HDMI 1.3a specification.

7.1 System clock

The system clock section has a PLL serializer.

It is a system clock generator which enables the stream produced by the encoder to be

transmitted on the HDMI data channel at ten times, or above, the sampling rate.

7.2 Video input formatter

7.2.1 Description

The TDA9989 has three video input ports VPA[7:0], VPB[7:0] and VPC[7:0].
