- (3) The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDECstandard test exists, but a close description can be found in the ANSI SEMI standard G30-88.
- (4) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8.
- (5) The junction-to-top characterization parameter, ψ JT , estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining R θ JA , using a procedure described in JESD51-2a (sections 6 and 7).

TUSB8041 Typical Application
The TUSB8041 is a four-port USB 3.0 compliant hub. It provides simultaneous SuperSpeed USB and highspeed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or low speed connections on the downstream port. The TUSB8041 can be used in any application that needs additional USB compliant ports. For example, a specific notebook may only have two downstream USB ports. By using the TUSB8041, the notebook can increase the downstream port count to five.
