Notes:
1. Current drawn from power supply, minimum output amplitude (mode 01).
2. Current drawn from power supply, mid output amplitude (mode 10).
3. Current drawn from power supply, maximum output amplitude (mode 11).
4. Current measurement was taken with a toggling pattern at 50 MHz is applied into the high-speed input channels at 50% duty cycle. All inputs and
outputs are turned on.
5. Current measurement was taken with input logic '0‘ applied to all control pins and a toggling pattern at 50 MHz is applied into the high-speed
input channels at 50% duty cycle. All inputs and outputs are turned on.

Notes:
1. Current measurement was carried out using a toggling pattern at maximum amplitude with 50% duty cycle
2. For input channels, the number of input channels turned on/off affects only the power supply current for VCC.
3. For output channels, the number of output channels turned on/off affects only the power supply currents for VCC and VCC_DOUT.
