PI3DPX20021

Overview

The PI3DPX20021 is a low-power, high-performance 20Gbps 4-channel Mux ReDriver supporting DisplayPort 2.0 UHBR20 transmission modes. It functions as a 2-to-1 multiplexer with four independent differential channels operating at 100Ω CML I/Os. The device provides programmable equalization, swing, and flat gain to optimize signal integrity over various physical mediums by reducing intersymbol interference. It features automatic receiver detect, adaptive power management for battery life extension, and transparent link training. The component operates on a 3.3V supply voltage within a temperature range of -40°C to +85°C.

• Programmable equalization, output swing, and flat gain via pin strap or I2C interface
• Adaptive power management feature designed to maximize battery life in portable devices

Applications

• Notebooks
• All-In-One PCs
• Gaming Workstations
• Desktop PCs

Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number requires the 'ZLD' package code and an 'E' suffix for lead-free/green status, followed by an 'X' suffix for tape and reel packaging. Confirm RoHS 3 compliance and halogen/antimony-free definitions against current manufacturer quality standards before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 2-to-1 mux configuration for DisplayPort signals up to 20Gbps. Ensure the design supports 3.3V logic levels and accommodates the 40-pin TQFN (3x6 mm) footprint. Verify that the host system can utilize the I2C or pin-strapping programming methods for configuring channel-specific equalization and gain parameters.
