Overview
The DS15BR401TSQX/NOPB is a 4-channel LVDS (Low Voltage Differential Signaling) buffer/repeater produced by Texas Instruments. This component is designed to handle high-speed data transmission up to 2 Gbps, making it suitable for various high-speed data communication applications. It features a flow-through pinout and high-speed data paths that minimize internal device jitter and simplify board layout. The device is particularly useful for overcoming ISI (Inter-Symbol Interference) jitter effects in lossy backplanes and cables through its pre-emphasis capability.
