16.1 ABSOLUTE MAXIMUM RATINGS
16.2 DC SPECIFICATIONS
(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect
reliability.
VDDA: analog power supply for PCI Express Interface
VDDP: digital power supply for PCI Express Interface
VDDAUX: digital auxiliary power supply for PCI Express Interface
VTT: termination power supply for PCI Express Interface
VDDC: digital power power supply for the core
VDDCAUX: digital auxiliary power supply for the core
VD33: digital power supply for PCI/PCI-X interface
VAUX: digital auxiliary power supply for PCI/PCI-X interface
In order to support auxiliary power management fully, it is recommended to have VDDP and VDDAUX separated.
By the same token, VD33/VDDC and VAUX/VDDCAUX need to be separated for auxiliary power management
support. However, if auxiliary power management is not required, VD33 and VDDC can be connected to VAUX
and VDDCAUX respectively.
The typical power consumption of PI7C9X110 is about 1.0 watt.
