AGND
GND
Analog Ground.
A common AGND, DGND, SGND plane is
highly recommended.
Analog Power Supply.
Voice Frequency Transmit Input.
This node requires a 10 M
or 20 M
resistance to AGND. The value is dependent upon the
gain of the XAG amplifier (register 146). 20 M
can be used for
any gain setting, 10 M
can only be used for XAG gain settings
of 0 dB and +6.02 dB.
Voice Frequency Receive Output, Positive Polarity.
This pin
can drive 2000
(or greater) loads.
Voice Frequency Receive Output, Negative Polarity.
This pin
can drive 2000
(or greater) loads.
