LOW VOLTAGE DIFFERENTIAL SIGNALING RECEIVER AND LOW VOLTAGE DIFFERENTIAL SIGNALING INTERFACE SYSTEM HAVING SAME

摘要

PROBLEM TO BE SOLVED: To provide a low voltage differential signaling receiver and a low voltage differential signaling interface system having the same.;SOLUTION: The low voltage differential signaling receiver includes a digital resistor unit configured to detect a voltage difference between a differential signal pair indicative of a first signal transmitted from outside and have a resistance value that may be varied under external control, a receiver unit configured to regenerate the first signal from the detected voltage difference detected by the digital resistor unit, and a resistance adjustment unit configured to generate and provide a control signal to the digital resistor unit to adjust the resistance value of the digital resistor unit. The low voltage differential signaling receiver unit must be equipped with the digital resistance composed of a transistor array instead of an external resistance, so characteristics of the signal are improved, the production stages are simplified, and it becomes easier to vary the resistance value.;COPYRIGHT: (C)2007,JPO&INPIT
