Description
Correlator output value (Timing extrapolation unit). The timing
extrapolation unit output value will be multiplied with the LFSAT
value. The timing extrapolation unit measures the data rate error during
the
RUNIN sequence and sets the I-Loop-Filter path when the RUNIN length
is
reached.

Loop Filter Saturation. The saturation of the I-Loop-Filter path will
be set according to the LFSAT
value.Remark that the internal phase resolution of the phase detector is
1/16 bit.

I Value. The IVAL is the I value of the Clock-Recovery PI Loop-Filter.
The Phase-
Detector output error will be multiplied with this set value.
