Overview
The SN65DP141RLJR, produced by Texas Instruments, is an asynchronous, protocol-agnostic, low-latency, four-channel linear equalizer designed to optimize data transmission up to 12 Gbps. This device is specifically tailored for use in DisplayPort and embedded DisplayPort (eDP) applications, compensating for signal losses due to board traces and cables. It is transparent to DisplayPort link training, allowing effective communication between the source and sink, and can be placed in various positions within the link, including source, cable, or sink, providing a negative loss component to the overall link budget.
