One chip CD audio device with integrated MP3/WMA decoder
The bandwidths and corresponding time-constant (t) of the decay filter are shown in
Table 4
, when the system clock frequency f
clk(sys)
is 10 MHz.
Peak detector based on window:
The functional schematic of this peak detection is
shown in
Figure 13
.
The minimum and maximum peaks of the incoming signal are measured during a
programmable window period. The highest and lowest sample within this window are used
to update maximum and minimum peaks.
The window width of the measurement is controlled via register AGCAOCControl bit
PDMEASWINDOW.
AGC and AOC control block:
The AGC control block controls the RF amplitude at the
input of the ADC by controlling the gain of an on-chip analog gain amplifier. The AOC
control block controls the RF offset at the input of the ADC by adding or subtracting the
offset just before the ADC. Both AGC and AOC loops are built up in the same manner and
are shown in
Figure 14
in their relative position within the signal conditioning block.
