Table 15. Si473x Property Summary (Continued)
Configures RDS setting.
Sets de-emphasis time constant. Can be set to 50 us. De-
emphasis is disabled by default.
Selects the bandwidth of the channel filter for AM/SW/LW recep-
tion. The choices are 6, 4, 3, 2, or 1 (kHz). The default band-
width is 2 kHz.
Configures interrupt related to RSQ metrics. All interrupts are
disabled by default.
Sets high threshold for SNR interrupt. The default is 0 dB.
Sets low threshold for SNR interrupt. The default is 0 dB.
Sets high threshold for RSSI interrupt. The default is 0 dB.
Sets low threshold for RSSI interrupt. The default is 0 dB.
Sets the rate of attack when entering or leaving soft mute. The
default is 278 dB/s.
Sets the AM/SW/LW soft mute slope. The bigger the number,
the higher the max attenuation level. Default value is a slope of
2.
Sets maximum attenuation during soft mute (dB). Set to 0 to dis-
able soft mute. Default is 16 dB.
Sets SNR threshold to engage soft mute. Default is 10 dB.
Sets the bottom of the AM/SW/LW band for seek. Default is 520. 0x0208
Sets the top of the AM/SW/LW band for seek. Default is 1720.
Selects frequency spacing for AM/SW/LW seek. Default is 10
kHz spacing.
Sets the SNR threshold for a valid AM/SW/LW Seek/Tune. If the
value is zero then SNR threshold is not considered when doing
a seek. Default value is 5 dB.
Sets the RSSI threshold for a valid AM/SW/LW Seek/Tune. If
the value is zero then RSSI threshold is not considered when
doing a seek. Default value is 25 dBuV.
Sets the output volume.
Mutes the audio output. L and R audio outputs may be muted
independently in FM mode.
