TL7231MD
External DAC Interfaces
TL7231MD supports eight external interface formats. Three of them, for example, are shown in
Figure 18. The interface can be configured through HIP commands. The frequency of
DACBCLK is 32 times of that of DACLRCK. When voice decoding, only 32KHz of DACLRCK
is used.
