Table 15. Si473x Property Summary
Sets the prescaler value for RCLK input.
Enables interrupt sources.
Configures the digital output sample rate in 100 Hz steps. The
digital output sample rate is disabled by default (Si4735 only).
Sets frequency of reference clock in Hz. The range is 31130 to
34406 Hz, or 0 to disable the AFC. Default is 32768 Hz.
Sets de-emphasis time constant. Default is 75 us.
Sets RSSI threshold for stereo blend (full stereo above thresh-
old, blend below threshold). To force stereo set this to 0. To
force mono set this to 127. Default value is 49 dBuV.
Sets RSSI threshold for mono blend (full mono below threshold,
blend above threshold). To force stereo set this to 0. To force
mono set this to 127. Default value is 30 dBuV.
Sets the maximum freq error allowed before setting the AFC rail
(AFCRL) indicator. Default value is 30 kHz.
Configures interrupt related to RSQ metrics.
Sets high threshold for SNR interrupt.
Sets low threshold for SNR interrupt.
Sets high threshold for RSSI interrupt.
Sets low threshold for RSSI interrupt.
Sets the blend threshold for blend interrupt when boundary is
crossed.
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 4 dB.
Sets the bottom of the FM band for seek. Default is 8750.
Sets the top of the FM band for seek. Default is 10790.
Selects frequency spacing for FM seek.
Sets the SNR threshold for a valid FM Seek/Tune. Default value
is 3 dB.
Sets the RSSI threshold for a valid FM Seek/Tune. Default
value is 20 dBuV.
Configures RDS interrupt behavior.
Sets the minimum number of RDS groups stored in the receive
RDS FIFO required before RDS RECV is set.
