Table 15. FM Receiver Settings Property Window Descriptions
Items
Description
AGC Attack Rate _{Larger values provide slower attack}
and smaller values provide faster attack.
AGC Index
If AGC override is set to “ON,” this property
will determine the AGC setting.
AGC Override
If set to “ON,” the AGC property will be used
to set the value of the AGC. If set to “OFF,”
the AGC setting will be automatically
determined by the part.
AGC Release Rate _{Larger values provide slower}
release and smaller values provide faster
release.
De-emphasis Selects de-emphasis of 50 µs or 75 µs.
Reference Clock
Frequency (Hz)
This field is used to specify the frequency of
the reference clock. The input to the RCLK
pin divided by the prescaler is the reference
clock. The reference clock must be in the
range of 31130 to 34406 Hz.
Reference Clock
Prescaler
This field is used to specify the prescaler
value. The input to the RCLK pin divided by
the prescaler is the reference clock. The
reference clock must be in the range of
31130 to 34406 Hz.
Digital DCLK Falling ON uses falling edge of DCLK for sampling.
