Overview
The SN65DP141RLJT, produced by Texas Instruments, is a quad-channel linear redriver designed to support high-speed data transmission over DisplayPort and embedded DisplayPort (eDP) interfaces. This device is optimized for use in applications requiring data rates up to 12 Gbps, including DisplayPort RBR, HBR, HBR2, HBR3, and UHBR10. It is protocol-agnostic, transparent to DisplayPort link training, and can be positioned independently within the link, making it suitable for source, sink, and cable applications.
The SN65DP141RLJT features low latency and asynchronous operation, compensating for signal losses due to board traces and cables. It also supports independent channel control for equalization, gain, and dynamic range through both I2C and GPIO configurations.
