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 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.
The RF AGC prevents overloading and limits the amount of intermodulation products
created by strong adjacent channels.
Fully integrated IF filter.
The FM quadrature demodulator has an integrated resonator to perform the phase shift of
the IF signal.
The FM IF analog level voltage is converted to 4 bits digital data and output via the bus.
The IF counter outputs a 7-bit count result via the bus.
The low-pass filtered level voltage drives the soft mute attenuator at low RF input levels.
The soft mute function can be switched off via the bus.
The PLL stereo decoder is adjustment-free. The stereo decoder can be switched to mono
via the bus.
