5.7.14 PCIEPHY DC Electrical Characteristics
NOTE
The PCIe interfaces are compliant with the electrical parameters specified in PCI Express®
Base Specification Revision 3.0.
5.8 Thermal Characteristics
For reliability and operability concerns, the maximum junction temperature of the Device has to be at or
below the T_J value identified in Table 5-4, Recommended Operating Conditions.
A BCI compact thermal model for this Device is available and recommended for use when modeling
thermal performance in a system.
Therefore, it is recommended to perform thermal simulations at the system level with the worst case
device power consumption.
5.8.1 Package Thermal Characteristics
Table 5-20 provides the thermal resistance characteristics for the package used on this device.
NOTE
Power dissipation of 1.5 W and an ambient temperature of 85ºC is assumed for ABC
package.

(1) These measurements were conducted in a JEDEC defined 2S2P system (with the exception of the Theta JC [RΘ_JC] measurement,
which was conducted in a JEDEC defined 1S0P system) and will change based on environment as well as application. For more
information, see these EIA/JEDEC standards:
