Group Delay
4.2.8.1
Table 10
shows the limit values for the Absolute Group Delay. The maximum delays are
valid when the SICOFI
4-μC is operating with H(TH) = H(IM) = 0, and H(FRR) = H(FRX)
= 1, and include the delay through the A/D and D/A converters. The typical delays are
the average of all different time slot delays during one PCM frame.
