PCM AND ADPCM INPUT/OUTPUT
Since the organization of the input and output time slots
on the DS2164Q does not depend on the algorithm se-
lected, 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
DS2164Q handles the I/O for the three different algo-
rithms. 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.

NOTE:
1. The bit after the LSB in the 24Kbps ADPCM output will only be a 1 when the DS2164Q is operated in the
software mode and is programmed to perform 24Kbps compression; in all other configurations, it will be a 0.
