Note
1. The function of pin 20, 28, 29, 31, 32, 35 and 44 is dependent on the IC version (mono intercarrier FM demodulator
2. The vertical guard function can be controlled via pin 49 or pin 50. The selction is made by means of the IVG bit in
Table 1
Note
1. When additional (external) selectivity is required for FM-PLL system pin 32 can be used as sound IF input. This
2. The reference output signal is only available for the CMB1/CMB0 setting of 0/1. For the other settings this pin is a
