V_REF worst case. Noise on V_REF should be accounted for. Refer to the Pentium^® Pro Family Developer’s
Manual for more information on V_REF.
Parameter measured into a 25 Ω resistor to V_TT (1.5 V).
A high level is maintained by the external pull-up resistors. AGTL+ is an open drain bus. Refer to the
Pentium^® Pro Family Developer’s Manual for information on V_TT.
(0 < V_IN < Vcc₃)
Total current for all V_REF pins.
(0 < V_OUT < Vcc₃)
Total of I/O buffer and package parasitics.
