Sound Carrier Frequency Offset Recovery:
Both
Mono and Stereo IF Carrier frequencies can be
adjusted independently (registers
CAROFFSET1
and
CAROFFSET2
) within a large range (up to
120 kHz for standard mono FM deviations) while the AUTOSTD system remains active. The
frequency offset estimation is written in registers
FM_DCL
and
FM_DCR
(Mono Left / Channel 1
And Mono Right / Channel 2, respectively) and can be used to implement the Automatic Frequency
Control (AFC) via an external I2C control.
If required, the AUTOSTD system can be disabled (Manual mode) and the user can control all
registers including those only controlled by the AUTOSTD function when active. Manual mode is
selected in registers
RESET
or
AUTO_SCKM
.
2.1.3
Sound Preprocessing and Selection
The demodulated sound signal can be redirected to 4 different output audio channels:
1. Loudspeaker & Subwoofer,
2. Headphone,
3. SCART,
4. I2S Interface.
Each output channel can independently select the demodulator source, analog SCART or I2S inputs
using register
CH_SEL
.
