  • Temperature control in an integrated circuit
    Patent number: 7649374
    Abstract: One example of a test board includes first and second communication ports configured for communication with a master device and a DUT, respectively. A bit error rate tester of the test board is arranged for communication with the master device and with the DUT by way of the first and second communication ports, respectively, and the bit error rate tester includes at least one IC whose maximum data rate is temperature sensitive. Finally, the test board includes a temperature control system arranged to control the IC temperature so that a maximum data rate of the IC can be adjusted through the use of thermal effects.
