Notes:
1. Frequency = 100 MHz.
2. This specification is a combination of core power (Icc₃), and power dissipated in the AGTL+ outputs and
I/O.
3. Iss is the maximum supply current consumption when all AGTL+ signals are low.
4. The Icc Specification does not include the AGTL+ output current to GND.
Table 12-8 lists the nominal specifications for the AGTL+ termination voltage (V_TT) and the
AGTL+ reference voltage (V_REF).

+/-9% during maximum di/dt and +/- 3% steady state, as measured at component V_TT pins.
Where VTT tolerance can range from - 9% to +9%, as noted above.
V_REF should be created from V_TT by a voltage divider of 1% resistors.
Some of the signals on the MIOC, PXB, MUX and RCG are in the AGTL+ signal group. These
signals are specified to be terminated to 1.5V. The DC specifications for these signals are
shown in Table 12-9.
