Note
1. When FM is selected, the control output FM-ON/OFF
(pin 42) is pulled to ground to switch-on the external
FM front-end. Pin 42 is an open-collector pin with a
series resistor R = 500 Ω.

Notes
1. FM value of the affected oscillators:
a) FM VALUE = FMRF + FMIF (for TEA5757HL).
b) FM VALUE = FMRF − FMIF (for TEA5759HL).
2. AM value of the affected oscillators:
AM VALUE = AMRF + AMIF.
