1: In the datasheet, why the AC voltage compliance range is -400mV? Can the pins of AOUT or AOUTB output negative voltage? what's the typical output waveform at AOUT pins and AOUTB?
2: please see attached figure, from this schematic, the AOUT is connected to PIN1 of the transformer, also is connected to GND by a 50 ohm resistor(same to AOUTB), Can the AOUT/AOUTB output the normal waveform because pin2 of the transformer is connected to GND? seems like AOUT is connected to GND.
