Functional description
7.1 Low noise RF amplier
The Low Noise Amplier (LNA) input impedance together with the LC RF input circuit
denes an FM band lter. The gain of the LNA is controlled by the RF Automatic Gain
Control (AGC) circuit to prevent overdrive of the subsequent circuits.
7.2 FM mixer
The FM quadrature mixer converts the received RF (76 MHz to 108 MHz) to the IF of
225 kHz. Downconversion is achieved by multiplication of the RF with the Local Oscillator
(LO) frequency. Image frequency suppression is achieved by using quadrature signal
processing.
7.3 VCO
The LC tuned VCO provides the local oscillator signal for the downconversion of the RF
signal to IF. The VCO is tuned to the double frequency required for the downconversion.
The LO is divided by two to provide the quadrature oscillator signals for the
downconversion process. The VCO frequency range is from 150 MHz to 217 MHz.
Integrated varactors are used for the VCO tuning. The only external component used for
the VCO is a coil.
7.4 Reference frequency
An external 32.768 kHz reference frequency is used as system clock. The reference clock
specications are given in Section 13.2.
The reference frequency is used for:
Synthesizer PLL reference frequency
Timing for the IF counter
Adjustment of the 38 kHz VCO for the stereo decoder
Auto alignment of the selectivity as well as the demodulator lters
Auto alignment of the 57 kHz RDS lter
7.5 Tuning system
The PLL synthesizer tuning system is suitable to operate with a 32.768 kHz reference
frequency. A 14-bit word is used to tune the radio, see Table 15. Calculation of this 14-bit
word shall be done as follows:
MPXOUT
E4
multiplex signal (MPX) output
VAFL
E5
left audio output
VAFR
E6
right audio output
