FUNCTIONAL DESCRIPTION
7.1
Low-noise RF amplifier
The LNA input impedance together with the LC RF input
circuit defines an FM band filter. The gain of the LNA is
controlled by the RF AGC circuit.
7.2
FM mixer
The FM quadrature mixer converts the FM RF
(76 MHz to 108 MHz) to an IF of 225 kHz.
7.3
VCO
The varactor tuned LC VCO provides the Local Oscillator
(LO) signal for the FM quadrature mixer. The VCO
frequency range is 150 MHz to 217 MHz.
7.4
Crystal oscillator
The crystal oscillator can operate with a 32.768 kHz clock
crystal or a 13 MHz crystal. The temperature drift of
standard 32.768 kHz clock crystals limits the operational
temperature range from
10
°
C to +60
°
C.
The PLL synthesizer can be clocked externally with a
32.768 kHz, a 6.5 MHz or a 13 MHz signal via pin XTAL2.
The crystal oscillator generates the reference frequency
for:
The reference frequency divider for the synthesizer PLL
The timing for the IF counter
The free-running frequency adjustment of the stereo
decoder VCO
The centre frequency adjustment of the IF filters.
7.5
PLL tuning system
The PLL synthesizer tuning system is suitable to operate
with a 32.768 kHz or a 13 MHz reference frequency
generated by the crystal oscillator or applied to the IC from
an external source. The synthesizer can also be clocked
via pin XTAL2 at 6.5 MHz. The PLL tuning system can
perform an autonomous search tuning function.
7.6
RF AGC
The RF AGC prevents overloading and limits the amount
of intermodulation products created by strong adjacent
channels.
