PI2DPX1264XUAEX

Signal Buffers, Repeaters, Splitters Overview

The PI2DPX1264XUAEX is a non-blocking DisplayPort 2.1/eDP 1.5 linear ReDriver with four channels, operating on a single 1.8V ±5% power supply. It supports data rates up to 13.5Gbps (UHBR13.5), including UHBR10, HBR3, HBR2, and RBR modes. The device features an integrated AUX listener for automatic power management and speed detection, enabling entry into D3 power-saving mode. It provides ultra-low latency of less than 300ps and allows individual I2C programmable control over CTLE gain and flat gain per channel. Active current consumption varies by lane count: 160mA typical for 4-lane, 80mA for 2-lane, and 40mA for 1-lane operation.
