Vcc (Pin 1): This is the positive power supply pin. Connect it to the power supply voltage, typically 3.3V to 5V. GND (Pin 2): This is the ground pin. It should be connected to the ground of the system. INx+ and INx- (Pins 3, 4, 7, 8, 11, 12, 15, 16): These are the differential input pins. They take the LVDS signal in a differential pair. The '+' pin is non-inverting, and the '-' pin is inverting. OUTx+ and OUTx- (Pins 5, 6, 9, 10, 13, 14): These are the differential output pins. The '+' pin is non-inverting, and the '-' pin is inverting. These outputs drive the LVDS signals to the load.Circuit Principle
The AM26LV31EIPWR is used to drive differential signals, which are used in high-speed data communication systems. It converts a single-ended input to a differential output, which is less susceptible to noise and allows for high-speed transmission over long distances. The inputs are differential, and the outputs are also differential.
This component uses the LVDS standard, which allows for high-speed signaling with lower power consumption compared to other signaling methods. The AM26LV31EIPWR can be used in various applications, such as video transmission, data transmission, and communications where differential signaling is required.
