TEA5762
Note
1. The output pins 30 and 31 can drive currents up to
5 mA; bits 19 (P0) and 18 (P1) control the output
voltage of the control pins P0 (pin 30) and P1 (pin 31):
a) Bit 19 (P0) LOW sets P0 (pin 30) to LOW.
b) Bit 19 (P0) HIGH sets P0 (pin 30) to HIGH.
c) Bit 18 (P1) LOW sets P1 (pin 31) to LOW.
d) Bit 18 (P1) HIGH sets P1 (pin 31) to HIGH.

Notes
1. FM value of the affected oscillators:
FM VALUE = FMRF + FMIF.
2. AM value of the affected oscillators:
AM VALUE = AMRF + AMIF.
Note
1. The given values for signal reception are
corresponding to a −3 dB point of 20 µV for FM.
