TDA9989
HDMI 1.3a transmitter with CEC support
Remark: Gamut-related metadata is an HDMI 1.3a feature.
7.7 Downsampler
This block works only with YCbCr input format; the lters downsample the Cb and Cr
signals by a factor of 2. A delay is added on the Y channel, which corresponds to the
pipeline delay of the lters, to put the Y channel in phase with the Cb-Cr channel.
7.8 Audio input format
TDA9989 is compatible with the following audio features described in the HDMI 1.3a
specication:
S/PDIF
I2S-bus up to two stereo channels
The TDA9989 can carry audio in I2S-bus format (one stereo to two stereo channels) or in
S/PDIF format through one audio pin named AP1. S/PDIF or I2S-bus format can be
selected via the I2C-bus. Only one audio format can be used at a time: either S/PDIF or
All audio ports are LV-CMOS 1.8 V compatible and LV-CMOS 3.3 V tolerant. It is possible
to map an internally unused port to internal ground via I2C-bus with ENA_AP register on
page 00h for both audio and clock inputs.
7.8.1 S/PDIF
In this format TDA9989 supports 2-channel uncompressed PCM data (IEC 60958) layout
0, or compressed bit stream up to 8 multi channels (Dolby Digital, DTS, AC3 etc.) layout 1.
The TDA9989 is able to recover the original clock from the S/PDIF signal (no need of
external clock).
7.8.2 I2S-bus
There is one I2S-bus stereo input, which enables 2 uncompressed audio channels to be
carried. The I2S-bus input interface receives an I2S-bus signal including serial data, word
select and serial clock.
