1. 0.5Vccci, or 0.5 x 3.3 or 1.65V
2. 0.6Vccci p-p around 1.65V or 1.65-1.1 to 1.65+1.1 or 0.55 to 2.75v

Adding capacitors will remove the DC offset of 1.65v making the output ±1.1V

1. \$0.5\cdot Vccci\$, or \$0.5 \times 3.3\$ or \$1.65V\$
2. \$0.6\cdot Vccci\$ p-p around 1.65V or \$1.65-1.1\$ to \$1.65+1.1\$ or \$0.55V\$ to \$2.75V\$

Adding capacitors will remove the DC offset of \$1.65V\$ making the output \$\pm 1.1V\$
