Property 0x220A FM_CHBW_ASSI200_MIN_MAX
The FM_CHBW_ASSI200_MIN_MAX property sets the maximum and minimum Channel Filter Bandwidth in kHz
based on ASSI200. 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:
The Si4750/51/52/53 do not support dynamic bandwidth control, hence MIN[7:0] = MAX[7:0]. The minimum of MAX[7:0]
of properties 0x2200, 0x2205, and 0x220A determines the Channel Filter Bandwidth. Default for Si4750/51/52/53 is 150
kHz.
Si4754/55/56/57-A10 Default: 0x9632
Si4754/55/56/57-A20/A30/A40, Default: 0x9650
Si4750/51/52/53 Default: 0x9696
Si475x/5xC-A55, Default: 0x964B
