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:
The video data input formats are:
It can also handle audio formats:
The TDA9989 is also designed to support CEC protocol. For more details about CEC,
refer to HDMI 1.3a specification .
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.
The TDA9989 has three video input ports VPA[7:0], VPB[7:0] and VPC[7:0].
