2.2.3 CDB47xxx-DCxx Daughtercard
The layout for the daughtercard shipped with the CDB47xxx is the same, regardless of which type of main
board (differential or single-ended) the customer orders. The daughtercard can be ordered populated with
either the CS47048, Cs47028, or CS47024 DSP. The daughtercard with CS47024 DSP is labelled and
referred to as CDB47xxx-DC24.
Figure 2-4 shows the top side of the CDB47xxx-DC48 daughtercard. The accompanying legend identifies
the main components of the board.
