PI3DPX8112ZLDEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX8112ZLDEX is a 1-to-2 Active DeMux linear ReDriver for 4-lane DisplayPort links, supporting data rates up to 13.5Gbps for DP2.0 (UHBR13.5) and 8.1Gbps for DP1.4. It features maximum equalizer gains of +15dB at 6.75GHz and +8.5dB at 4.05GHz to compensate for channel insertion loss. The device operates on a single 3.3V +/-0.3V power supply within an industrial temperature range of -40°C to +85°C. It utilizes quad-level pin strap control for equalizer gain, flat gain, and output swing linearity selection, housed in a 40-pin TQFN package.
