Property 0x350B FM_BLEND_MULTIPATH_RELEASE_TIME
The FM_BLEND_MULTIPATH_RELEASE_TIME property sets the transition time for which the stereo blend
mitigation engine increases the stereo separation based on RSSI. 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.
Default: 4000
Units: ms
Property 0x3510 FM_BLEND_USN_THRESHOLDS
The FM_BLEND_USN_THRESHOLDS property sets the USN thresholds for maximum and minimum stereo
separation (set by Property 0x3511) on the blend engine. 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.
Default: 0x341B
Units: –dBFS

USNMIN[7:0]
Sets the USN Min threshold. If USN is below this threshold, maximum ste-
reo separation will be achieved as set by property 0x3511.
Default is –52 dBFS. Range is 0–127 –dBFS.
7:0
USNMAX[7:0]
Sets the USN Max threshold. If USN is above this threshold, minimum ste-
reo separation will be achieved as set by property 0x3511.
Default is –27 dBFS. Range is 0–127 –dBFS.
