HIGH-SPEED DIGITAL GALVANIC ISOLATOR WITH INTEGRATED LOW-VOLTAGE DIFFERENTIAL SIGNAL INTERFACE

摘要

PPROBLEM TO BE SOLVED: To provide various kinds of high-speed digital galvanic isolators and corresponding integrated low-voltage differential signal (LVDS) interfaces. PSOLUTION: Phantom power is provided to one side of a galvanic isolator from the other side of the isolator via a twisted pair cable with shielding interconnecting the two sides, and therefore eliminate the need to provide power to both sides of the galvanic isolator by different power supplies or by way of separate physical wirings being routed and connected to the two opposing sides of the isolator. Such phantom power supply configurations reduce cost, lower power consumption, and increase the number of engineering design options available in a device where high speed serial data communication with low noise level are required.
