Note
1. The function of pin 20, 28, 29, 31, 32, 35 and 44 is dependent on the IC version (mono intercarrier FM demodulator
/ QSS IF amplifier and East-West output or not) and on some software control bits. The valid combinations are given
in table 1.
2. The vertical guard function can be controlled via pin 49 or pin 50. The selection is made by means of the IVG bit in
subaddress 2BH.

Note
1. When additional (external) selectivity is required for FM-PLL system pin 32 can be used as sound IF input. This
function is selected by means of SIF bit in subaddress 28H.
2. The reference output signal is only available for the CMB1/CMB0 setting of 0/1. For the other settings this pin is a
switch output (see also table 67).
