PCM AND ADPCM INPUT/OUTPUT

Since the organization of the input and output time slots on the DS2164Q 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 DS2164Q handles the I/O for the

three different algorithms. In the figure, it is assumed that channel X is in the compression mode

(CP/

= 1) and channel Y is in the expansion mode (CP/

= 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 DS2164Q is operated

in the software mode and is programmed to perform 24kbps compression; in all other configurations, it is

a 0.
