VSC7146

2.5Gb/s, 20-Bit Transceiver

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 90oC. The user must guarantee that the temperature specification is not violated.
