INTERGRATED AND SWITCHABLE LINE TERMINATION

摘要

PURPOSE: An integrated and switchable line termination is provided to achieve effective digital expression signalling. CONSTITUTION: The line receiver circuit includes an integrated input amplifier circuit and a line receiver circuit. The integrated input amplifier circuit(1) has a noninverting input terminal(11) and an inverting input terminal(12) for connection with a transmission line(31,32). The line receiver circuit includes line impedance termination means(2) for terminating the characteristic impedance of the transmission line(31,32). The input amplifier circuit(1) and the line impedance termination means(2) are integrated on a common semiconductor substrate.
