Please refer to the table below for a simple example of a line driver. 75V has to be present at the encoder’s supply voltage input to ensure its operation. The FIN1002M5X is a 1-bit Differential Receiver for high speed interconnects utilizing Low Voltage Differential Signalling (LVDS) technology. Altera® 28-nm Cyclone ® V devices provide transceivers with the lowest power requirement at 3. Everything works fine. In Differential Phase Shift Keying (DPSK) the phase of the modulated signal is shifted relative to the previous signal element. Servo control systems are best suited to high speed, high torque applications that involve dynamic load changes. This resistor should be approximately equivalent.
