Parameter Description Min Value
Max
Value
Default
Value
peakWaitTime
Number of gain control clock cycles to wait before enabling
peak detectors after a gain change.
0 31 4
maxGainIndex
Maximum gain index allowed. Must be greater than
minGainIndex and be a valid gain index.
195 255 255
minGainIndex
Minimum gain index allowed. Must be less than maxGainIndex
and be a valid gain index.
195 255 195
gainUpdateCounter
Is used as a decision period, with the detectors reset on this
period. Gain changes in AGC mode can also be synchronized to
this period (the expiry of this counter). The full period is a
combination of the gainUpdateCounter and
slowLoopSettlingDelay and a number of AGC cycles.

attackDelay_us
The duration the AGC should be held in reset when the Rx path
is enabled.
0 63 10
slowLoopSettlingDelay
Number of AGC clock cycles to wait after a gain change before
the AGC will change gain again.
0 127 16
lowThreshPreventGainInc Only relevant in Peak and Power Detect AGC operation.
1: If AGC is in Peak and Power Detect Mode, then gain
increments requested by the power detector are prevented if
there are sufficient peaks (APD/HB Low Threshold Exceeded
Count) above the apdLowThresh or hbUnderRangeHighThresh.
0: apdLowThresh and hbUnderRangeHighThresh are don’t
cares for gain recovery.
