Overview
The DS25BR110TSD/NOPB is a high-speed, single-channel LVDS (Low Voltage Differential Signaling) buffer designed by Texas Instruments. This device is optimized for transmitting high-speed signals over lossy FR-4 printed circuit boards and balanced metallic cables. It features four levels of receive equalization, which significantly reduce Inter-Symbol Interference (ISI) jitter, making it ideal for applications requiring high signal integrity and noise immunity.
