Antenna diversity circuit
Objective specification
TEA6101/T
Mode selection
The diversity system is intended for FM reception. To
avoid an audible disturbance if it is used with an AM
system, the circuit can be reset. In the reset mode antenna
1 (pin 17 (19)) is selected and both comparators are
switched off to prevent pulses reaching the output.
For FM search tuning the diversity system may be similarly
disabled. The selected antenna will again be retained with
the comparators being inhibited.
Test pin
Although intended for test purposes the test pin can be
used to increase the audio offset (resistor from pin 10 (12)
to ground) or to change the compensation factor (resistor
between pin 8 (8) and 10 (12)). These modifications permit
the behaviour of the antenna switch to be adapted to
alternative IF amplifier IC's.
