Description
Default
Bits[15:12]
AVC maximum gain
Used to control the maximum gain in the range of 0 dB to 15 dB. This is the maximum gain
that can be applied to the input signal to reach the desired output level.
0011
0x0 = 15 dB
0x1 = 14 dB
0x2 = 13 dB
0x3 = 12 dB
0x4 = 11 dB
0x5 = 10 dB
...
0xF = 0 dB
Bits[11:8]
AVC decay time
Used to control the decay time in the range of 20 ms to 12 sec. The decay time
corresponds to the time required for the output to reach the desired level.
0101
0x0 = 20 ms
0x1 = 100 ms
0x2 = 200 ms
0x3 = 500 ms
0x4 = 1 sec
0x5 = 2 sec
0x6 = 3 sec
0x7 = 4 sec
0x8 = 5 sec
0x9 = 6 sec
0xA = 7 sec
0xB = 8 sec
0xC = 9 sec
0xD = 10 sec
0xE = 11 sec
0xF = 12 sec
Bits[7:4]
AVC maximum attenuation
Used to control the maximum attenuation in the range of 18 dB to 3 dB in
+1 dB steps. This is the maximum attenuation that can be applied to the input
signal to reach the desired output level.
0000
0x0 = 18 dB
0x1 = 17 dB
0xE = 4 dB
0xF = 3 dB
Bits[3:0]
AVC output level
Used to control the required output level of the AVC block in the range of 3 dBFS to
18 dBFS in 1 dB steps. If the input signal is greater than the output level that has
been set by these bits, the gain is automatically reduced.
1100
0x0 = 18 dBFS
0x1 = 17 dBFS
0xC = 6 dBFS
0xD = 5 dBFS
0xE = 4 dBFS
0xF = 3 dBFS
