Vreg
1.6 (FM)
1.3 (AM)
The FM SD bandwidth can be adjusted by changing
the value of the external resistor inserted between
pin 28 and pin 4, the regulator voltage.
The oscillator coil is connected between pin 29 and
pin 4, the regulator voltage.
The FM SD sensitivity can be adjusted by changing
the value of the external resistor inserted between
this pin and ground. The AM SD sensitivity must be
adjusted before the AM FD sensitivity.
Output impedance ro = 200
