Property 0x2205 AM_CHBW_ASSI_MIN_MAX (Si4754/55/56/57 Only)
The AM_CHBW_ASSI_MIN_MAX property sets the maximum and minimum Channel Filter Bandwidth in units of
100 Hz. Based on adjacent signal strength indicator (ASSI.) To force a given Channel Filter Bandwidth, set the min
and max to the same value. The CTS bit (and optional interrupt) is set when it is safe to send the next command.
This property may only be set or read in powerup mode.
Note:
Si4750/51/52/53 do not support dynamic bandwidth control, but MIN[7:0] = MAX[7:0] can determine the channel filter
setting.
Si475x-A10 is not available.
Si475x-A20 and later, Default: 0x3232.
Units: 100 Hz
