SAF784x
One chip CD audio device with integrated MP3/WMA decoder
and CD-text decoder, available for readout through the sub-CPU interface. The main data
stream is error-corrected by the ERCO, while the memory processor takes care of the
CIRC de-interleaving and buffering of data in a FIFO. At the back end of the channel
decoder, corrupted audio samples can be interpolated and held, while a burst of errors
can trigger the mute block. Detection of digital silence can be used to kill the internal or
external audio DAC. Pre-emphasis on the audio disc can be removed via the de-emphasis
filter, and the data can be 4
×
upsampled before it is sent to the audio DAC. CD data is
output via the I
2
S and/or the EBU outputs. Motor control can be frequency-regulated to
the incoming RF bit rate, with additional phase regulation by FIFO filling, or it can be fully
controlled via software. This method guarantees CLV support. A tacho measurement
block is also available. The motor can also be regulated by the tacho frequency which
allows possible CAV support.
Debug information is available via registers, via the dedicated serial lines Meas1 and Cflg.
The ARM AHB address of registers that control specific logic are shown next to each
functional block in
Figure 8
