Working Principles

The SN65LVDS31NSR is designed to convert low-voltage TTL/CMOS signals into LVDS signals. It utilizes differential signaling, where data is transmitted as a pair of complementary signals with opposite polarities. This technique allows for high-speed data transmission while minimizing electromagnetic interference.

The driver receives TTL/CMOS signals at the A and B inputs, which are then converted into LVDS signals at the YA and YB outputs. The enable input (EN) controls the driver's operation, allowing for easy on/off switching.
