7.7 Downsampler
7.8 Audio input format
Remark: Gamut-related metadata is an HDMI 1.3a feature.
This block works only with YCbCr input format; the filters 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 filters, to put the Y channel in phase with the Cb-Cr channel.
TDA9989 is compatible with the following audio features described in the HDMI 1.3a
specification:
The TDA9989 can carry audio in I
S/PDIF format through one audio pin named AP1. S/PDIF or I

I
Table 16.
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 I
page 00h for both audio and clock inputs.
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).
There is one I
