TDA19989 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 video data input formats are:
TDA19989 is able to output HDMI with the formats:
It can also handle audio formats:
TDA19989 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.
