FPSC Maximum Junction Temperature
Once the power dissipated by the FPSC has been determined (see the Estimating Power Dissipation section), the
maximum junction temperature of the FPSC can be found. This is needed to determine if speed derating of the
device from the 85 C junction temperature used in all of the delay tables is needed. Using the maximum ambient
temperature, TAmax, and the power dissipated by the device, Q (expressed in C), the maximum junction tempera-
ture is approximated by:
TJmax = TAmax + (Q * ΘJA)
Table 20 lists the thermal characteristics for all packages used with the ORCA ORLI10G FPSC.

Table 20. ORCA ORLI10G Plastic Package Thermal Guidelines
The ORLI10G in a 680 PBGAM1T package has ΘJC of 3.5 deg C/W.
Heat Sink Vendors for BGA Packages
The estimated worst-case power requirements for the ORLI10G with a programmable XGMII to XSBI interface for
10 Gbits/s Ethernet applications is 4 W to 5 W. Consequently, for most applications an external heat sink will be
required. Below, in alphabetical order, is a list of heat sink vendors who advertise heat sinks aimed at the BGA mar-
ket.
