Table 17. Si471x Property Summary
Enables interrupt sources.
Configures the digital input format.
Configures the digital input sample rate in 10 Hz steps.
Default is 0.
Sets frequency of the reference clock in Hz. The range is
31130 to 34406 Hz, or 0 to disable the AFC. Default is
32768 Hz.
Sets the prescaler value for the reference clock.
Enable transmit multiplex signal components.
Default has pilot and L-R enabled.
Configures audio frequency deviation level. Units are in
10 Hz increments. Default is 6285 (68.25 kHz).
Configures pilot tone frequency deviation level. Units are
in 10 Hz increments. Default is 675 (6.75 kHz)
Configures the frequency of the stereo pilot. Default is
19000 Hz.
Enables audio dynamic range control.
Default is 0 (disabled).
Sets the threshold level for audio dynamic range control.
Default is –40 dB.
Sets the attack time for audio dynamic range control.
Default is 0 (0.5 ms).
Sets the release time for audio dynamic range control.
Default is 4 (1000 ms).
Sets the gain for audio dynamic range control.
Default is 15 dB.
Sets the limiter release time. Default is 102 (5.01 ms)
Configures measurements related to signal quality met-
rics. Default is none selected.
Configures low audio input level detection threshold.
This threshold can be used to detect silence on the
incoming audio.
Si4711 Only. Configures the RDS/RBDS frequency
deviation level. Units are in 10 Hz increments. Default is
2 kHz.
Configures maximum analog line input level to the
LIN/RIN pins to reach the maximum deviation level pro-
grammed into the audio deviation property TX Audio
Deviation. Default is 636 mV
Sets line input mute. L and R inputs may be indepen-
dently muted. Default is not muted.
Configures pre-emphasis time constant.
Default is 0 (75 µS).
