Product data sheet
8.1 Low noise RF amplifier
8.2 FM I/Q mixer
8.3 VCO
8.4 Crystal oscillator
Table 3:
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.
FM quadrature mixer converts FM RF (76 MHz to 108 MHz) to IF.
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.
The crystal oscillator can operate with a 32.768 kHz clock crystal. The oscillator can be
overridden via the FREFIN pin. When the FREFIN pin is used the oscillator is clocked
externally by a 32.768 kHz signal. Selection between a reference clock or a reference
crystal can be done via the I
left open-circuit, and when pin FREFIN is used a crystal may not be connected. It is not
possible to connect a crystal and apply a frequency via the FREFIN pin in the same
application.
