Inhibitable, continuously-terminated differential drive circuit for an integrated circuit tester |
摘要 |
A drive circuit for an integrated circuit tester operates in either a drive mode of a termination mode. In the drive mode, the drive circuit supplies a differential test signal to an integrated circuit device under test (DUT) via a pair of transmission lines. In its termination mode, the drive circuit terminates the transmission lines with their characteristic impedances and provides an adjustable load to a DUT output signal appearing on the transmission lines.
