Group Delay
The data input to data output group delay is the delay
which occurs due to the digital filter calculations. It
is the time between the serial input data is com-
pletely read in (at rate fs) until the serial data is out-
put (at rate 8fs or 4fs, depending on the mode
selected).
t
INPUT
represents the LRCI clock rising edge after
the serial input data has been read in at rate fs.
t
OUTPUT
represents the WCKO clock falling edge at
the start of serial data output at rate 8fs or 4fs.
