PIN AND FUNCTIONAL DESCRIPTIONS
AIN1, AIN2, GSX1, GSX2
AIN1 and AIN2 are the transmit analog inputs for channels 1 and 2.
GSX1 and GSX2 are the transmit level adjustments for channels 1 and 2.
AIN1 and AIN2 are inverting inputs for the op-amp; GSX1 and GSX2 are connected to the output
of the op-amp and are used to adjust the level, as shown below.
When not using AIN1 and AIN2, connect AIN1 to GSX1 and AIN2 to GSX2. During power saving
and power down mode, the GSX1 and GSX2 outputs are at AG voltage.
AOUT1, AOUT2
AOUT1 is the receive analog output for channel 1 and AOUT2 is used for channel 2.
The output signal has an amplitude of 3.4 V
PP
above and below the signal ground voltage (SG).
When the digital signal of +3 dBmO is input to DIN1 and DIN2, it can drive a load of 600
W
or
more.
During power saving or power down mode, these outputs are at the voltage level of SG with a
high impedance.
