Additional Details

The DS90LT012AQMF operates from a single 3.3V power supply. It drives differential signals across a balanced transmission line, typically a twisted-pair cable. The device is designed to meet the requirements of the ANSI TIA/EIA-644 LVDS standard. Proper termination is essential for optimal performance of LVDS links. Common-mode noise rejection is a key benefit of LVDS technology. The component package is typically a small outline package (SOP) or a quad flat no-leads (QFN) package.
