signals by a factor 2. A delay is added on the G/Y channel, which corresponds to the
pipeline delay of the filters, to put the Y channel in phase with the C

Table 15.
All audio ports are LV-TTL compatible.
The audio port AP6 is used for the S/PDIF feature. In this format the TDA9983B supports
2-channel uncompressed PCM data (IEC 60958) layout 0 or compressed bit stream up to
8 multichannels (Dolby Digital, DTS, AC-3, etc.) layout 1. The TDA9983B is able to
recover the original clock from the S/PDIF signal (no need for an external clock). In
addition it can also use an external clock (MCLK) to decode the S/PDIF signal.
The TDA9983B supports the NXP I
channels (AP1 to AP4), which enable 8 uncompressed audio channels to be carried. The
