Currents at VTTI and VTTO count in power dissipation, but are not included in ICC. Note that in a CML output structure with separate termination supplies, all of the output and input current is drawn from VTTI and the termination resistors, not from Vcc. 2 Power dissipation includes power due to 800 mV p-p differential input and output voltages; this is the true representation of power dissipated on and used by the chip at an 800 mV p-p differential signal level. |
