Description
Set bits to 0.
SIA1 EQ Control - total of 24 levels
(3 gain stages with 8 settings)
[5]: Enable EQ
[4:3]: Gain Stage Control
[2:0]: Boost Level Control
Register [EN] [GST] [BST] = Hex Value
100000 = 20'h = Bypass (Default)
101010 = 2A'h = 5 dB at 3 GHz
110000 = 30'h = 9 dB at 3 GHz
110010 = 32'h = 11.7 dB at 3 GHz
111001 = 39'h = 14.6 dB at 3 GHz
110101 = 35'h = 18.4 dB at 3 GHz
110111 = 37'h = 20 dB at 3 GHz
111011 = 3B'h = 21.2 dB at 3 GHz
111101 = 3D'h = 28.4 dB at 3 GHz
Set bits to 0.
De-assert = [3:2], assert = [1:0]
00 = 110 mV, 70 mV (Default)
01 = 150 mV, 110 mV
10 = 170 mV, 130 mV
11 = 190 mV, 150 mV
Set bits to 0.
0: Allow IDLE_sel control in Bit 4
1: Automatic IDLE detect
0: Output is ON (SD is disabled)
1: Output is muted (electrical idle)
Set bits to 0.
