Baseband Filter 1 Bandwidth.
00b = 100 MHz.
01b = 65 MHz. Use this setting for 30–45 MSps operation.
10b = 40 MHz. Use this setting for 20–30 MSps operation.
11b = 35 MHz. Use this setting for 1–20 MSps operation.
Baseband Filter 2 Bandwidth.
The filter bandwidth set is given by:
BW = 2 + BBFil2BW[5:0]
The bandwidth is adjustable in 63 steps with a step size of 1 MHz. The bandwidth range is 2 MHz to
Baseband VGA2 Offset Control.
000b = –41 dB.
100b = –39 dB.
010b = –37 dB.
110b = –35 dB.
001b = –33 dB.
101b = –31 dB. Use this setting when fixed gain settings are desired.
011b = –29 dB. Use this setting for minimum signal levels.
111b = –27 dB. Use this setting for maximum signal levels.
