II.5.3- Line LossCompensation /
A.G.C. Adjustment
The characteristics of the A.G.C. stage in the re-
ceive path are the same as those in the transmit
path.
For more informationsee SectionII.3.3.
II.5.4- A.G.C. Inhibition
The characteristicsof theA.G.C. inhibitionstagein
the receive path are the same as those in the
transmitpath.
For more informationsee SectionII.3.4.
II.5.5- +6dB Mode
Through the serial bus interface, it is possible to
increase the receivegain amplifier by 6dB.
This code (0010110)is a togglecode.
II.6 - Handsfree Interface
Figure 44 shows the interconnection between
TEA7092and Handsfreecircuit such as TEA7540.
TEA7092shouldbeinHandsfreemode(0110010).
The Handsfree circuit is supplied through the
Pin V
LS
(Pin1)
In
this
mode
the
Pin HFIN (Pin 22) is amplified, the antiacoustic
feedback stage is inhibited and the loudspeaker
amplifieris activated.
