PIN AND FUNCTIONAL DESCRIPTIONS
AIN1, AIN2, GSX1, GSX2
Transmit analog inputs and the output for transmit gain adjustment.
AIN1 (AIN2) connects to the inverting input of the internal transmit amplifier. GSX1 (GSX2)
connects to the internal transmit amplifier output. Refer to Fig. 1 for gain adjustment.
VFRO, AOUT+, AOUT鈥? PWI
Receive analog output and the output for receive gain adjustment.
VFRO is the receive filter output. AOUT+ and AOUT鈥?are differential analog signal outputs
which can directly drive Z
