− ±2 A source and sink current
− Down to 20 ps jitter
− Low 2nd harmonic distortion
− CW half bridge:
− ±0.3 A source and sink current
− Down to 10 ps jitter
− Very low power consumption
• Fully integrated real clamping-to-ground
function
− 8 Ω synchronous active clamp
− ±2 A source and sink current
• Fully integrated TR switch
− 8 Ω ON resistance
− Up to 300 MHz BW
− Current consumption down to 10 μA in
RX phase
