1. R
2. Current is measured on all Vcc pins @ Vcc = 3.3 V.
3. Transmitter current is measured with a 1:1 transformer. Transmitter peak current is governed by the following equation:
1. This value is measured across the receive differential pins, TPIP and TPIN.

3. Transmitter current is measured with a 1:1 transformer. Transmitter peak current is governed by the following equation:
maximum differential output peak voltage divided by the load resistance value.
maximum differential output peak voltage divided by the load resistance value.
