ezLINX™ iCoupler® Isolated Interface Development Environment Homepage
The Isolated LVDS port is implemented using the ADuM3442 iCoupler signal isolator, the ADN4664 dual LVDS receiver, the ADN4663 dual LVDS transmitter and the ADuM5000 isoPower Isolated DC to DC converter. The ADuM3442 is connected to SPORT2 of the ADSP-BF548. Figure 1 below shows a circuit diagram of the implementation of Isolated LVDS using the ADuM3442, ADN4663, ADN4664 and ADuM5000 on the ezLINX hardware.
VDD1 of the ADuM3442, and VDD1 of the ADuM5000 are powered by 3.3V. The ADuM5000 will generate an isolated 3.3V and is used to supply power to VDD2 of theADuM3442, VCC of the ADN4663 and the ADN4664.
A 32 pin header connector is used for easy access to the Isolated LVDS signals.
