VOH spec does not apply to signals that are open drain driver. Open drain signals must have an
external pull up resistor.
49.5.19.3 IICH Miscellaneous Signals AC Characteristics
The AC electrical specifications of the EP80579 IICH Miscellaneous signals are
compliant with the PCI Local Bus Specification, Rev. 3.0 (refer to AC Specifications for
3.3V Signaling for more information).
49.5.20
Clock Resource Unit (CRU)
The CRU unit is responsible for generating and distributing the clocks to the various
functional units within the SOC.
This section describes the electrical characteristics of the Global Clock signals.
49.5.20.1 CRU Signal List
For a pin description for the CRU Signals, refer to Table 48-5, “Global Clock and Reset
(CRU) Signals” on page 1736.
