Typically, SRTS nibbles delivered by the AAL1gator II oscillate between two values, such as
1100b and 1011b. To smooth out the resulting clock jitter, a more sophisticated mapping from
SRTS nibbles to 8-bit DAC codes can be used. Some examples of such mappings are averages
and running averages that access a lookup table with finer resolution than that provided by the
SRTS nibbles.
