Working Principles

The SN65LVDS19DRFT is a LVDS driver IC that converts single-ended CMOS/TTL input signals into differential LVDS output signals. It utilizes low-voltage differential signaling, where data is transmitted as the voltage difference between two complementary signals. This method provides noise immunity and allows for high-speed data transmission over long distances.

The IC operates by receiving the single-ended input signal at the IN pin. It then converts this signal into a differential LVDS output at the OUT pin. The enable (EN) pin controls the operation of the driver, allowing the user to enable or disable the output as needed.
