PCM AND ADPCM INPUT/OUTPUT
Since the organization of the input and output time slots on the DS2165 does not depend on the algorithm
selected, it always assumes that PCM input and output will be in 8-bit bytes and that ADPCM input and
output will be in 4-bit bytes. Figure 12 demonstrates how the DS2165 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.
PCM AND ADPCM I/O EXAMPLE Figure 12
NOTE:
1. The bit after the LSB in the 24kbps ADPCM output will only be a 1 when the DS2165 is operated in
the software mode and is programmed to perform 24kbps compression; in all other configurations, it
will be a 0.
