2.3 Assembly Options for Ease of
Manufacture
There are variety of options available on a build of
the CRD42528 that allow for different input and
output options, as well as performance differentia-
tion. This allows the same board to be used in both
low-end and high-end applications. Please note that
systems with lower performance may require exter-
nal analog Bass Management circuitry to comply
with Dolby specifications.
2.3.1 Analog Input Options
The CRD42528 supports 2, 6, or 8 channels of an-
alog input. A list of components that needs to be
populated for each configuration is shown in
