Overview
The DS15BR401TSQX is a 4-channel LVDS (Low-Voltage Differential Signaling) buffer/repeater produced by Texas Instruments. This component is designed to support high-speed data transmission up to 2 Gbps, making it suitable for various high-speed applications. It features a flow-through pinout and internal 100 Ω termination resistors to minimize internal device jitter and simplify board layout. The device operates on a single 3.3V supply and is available in space-saving WQFN-32 and TQFP-48 packages, making it ideal for applications requiring signal repeating and buffering over long distances.
