Advance Product Information
VSC7146
2.5Gb/s, 20-Bit Transceiver
G52162-0, Rev. 2.7
Package Thermal Characteristics
The VSC7146 is packaged in an 80-pin, 14mm thermally-enhanced EDQUAD with an internal heat
spreader. These packages use industry-standard EIAJ footprints, which have been enhanced to improve thermal
dissipation. The construction of the packages are as shown in Figure 11. The VSC7146 is designed to operate
with a case temperature up to 90
o
C. The user must guarantee that the temperature specification is not violated.
