THEORY OF OPERATION
The delta-sigma section of PCM1716 is based on a 8-level
amplitude quantizer and a 4th-order noise shaper. This
section converts the oversampled input data to 8-level delta-
sigma format.
This newly developed, “Enhanced Multi-level Delta-Sigma”
architecture achieves high-grade audio dynamic performance
and sound quality.
A block diagram of the 8-level delta-sigma modulator is
shown in Figure 9. This 8-level delta-sigma modulator has
the advantage of stability and clock jitter sensitivity over the
typical one-bit (2 level) delta-sigma modulator.
The combined oversampling rate of the delta-sigma modu-
lator and the internal 8-times interpolation filter is 64f
S
for
all system clock ratios (256/384/512/768f
S
).
The theoretical quantization noise performance of the
8-level delta-sigma modulator is shown in Figure 10. This
enhanced multi-level delta-sigma architecture also has ad-
vantages for input clock jitter sensitivity due to the multi-
level quantizer, simulated jitter sensitivity is shown in
Figure 11.
