Abstract

Disclosed is a circuit that optimises the serial line termination for high speed push-pull drivers. The invention consists in replacing a single series resistor by a network made of two resistors and one Schottky diode. A point to point transmission line is made of one driver , the transmission line, the receiver and the termination. The classic series termination consist in a serial resistor Rs located at the front end of the line back to the driver (see Figure 1). DRIVER Vdd
