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 specication.
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].
