PCM AND ADPCM INPUT/OUTPUT
Since the organization of the input and output time slots on the DS2165Q does not depend on the
algorithm selected, it always assumes that PCM input and output are in 8-bit bytes and that ADPCM
input and output are in 4-bit bytes. Figure 12 demonstrates how the DS2165Q handles the I/O for the
three different algorithms. In the figure, it is assumed that channel X is in the compression mode
(CP/ EX = 1) and channel Y is in the expansion mode (CP/ EX = 0). Also, it is assumed that both the input
and output time slots for both channels are set to 0.
Figure 12. PCM AND ADPCM I/O EXAMPLE
Note 1: The bit after the LSB in the 24kbps ADPCM output is only a 1 when the DS2165Q is operated
in the software mode and is programmed to perform 24kbps compression; in all other configurations, it is
a 0.
