Overview
The DS15BR401TSQ is a 4-channel LVDS buffer/repeater designed to handle high-speed data transmission up to 2 Gbps. It is part of the DS15BR400/DS15BR401 family from Texas Instruments. This component is optimized for applications requiring low jitter, high noise immunity, and low power operation. The device features a flow-through pinout and high-speed data paths, which minimize internal device jitter and simplify board layout. The pre-emphasis capability helps overcome ISI (Inter-Symbol Interference) jitter effects from lossy backplanes and cables.
