12 ELECTRICAL AND TIMING SPECIFICATIONS
12.1 ABSOLUTE MAXIMUM RATINGS
Table 12-1 Absolute maximum ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Storage Temperature
-65oC to 150oC
Ambient Temperature with power applied
-40oC to 85oC
PCI Express supply voltage to ground potential (VDDA, VDDC, and
VDDCAUX)
-0.3v to 3.0v
DC input voltage for PCI Express signals
-0.3v to 3.0v
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
VDDR: digital power supply for 3.3v I/O Interface
VDDC: digital power supply for the core
VAUX: digital auxiliary power supply for 3.3v I/O Interface
VDDCAUX: digital auxiliary power supply for the core
VTT: transmit termination power supply for PCI Express Interface
In order to support auxiliary power management fully, it is recommended to have VDDC and VDDCAUX
separated.
The typical power consumption of PI7C9X20404GP is about 0.8 watt.
