Notes
1. Signal amplitude of 50 mA black-to-white is possible if the average current (including blanking times and signal
variation against time) does not exceed 50 mA. The maximum power dissipation of 1200 mW has to be considered.
2. Equivalent to discharging a 200 pF capacitor through a 0 Ω series resistor.
