Working Principles

The PI90LV028AWEX operates by receiving low-voltage differential signals at its input pins (IN+ and IN-) and converting them to higher voltage levels at the output pins (OUT+ and OUT-). This conversion is achieved using internal circuitry that amplifies and shapes the input signals. The device also provides an enable pin (EN) to control its operation, allowing users to selectively activate or deactivate the signal conversion process.
