PIN DESCRIPTION
AIN1, AIN2, GSX 1, GSX 2
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 channel1 and AOUT2 is used for channel2.
The output signal has an amplitude of 3.4Vpp above and below the signal ground
voltage(SG).When the digital signal of +3dBm0 is input to DIN, it can drive a load of
600
or more.
During power saving or power down mode, these outputs are at the voltage level of
SG with a high impedance.
