PI3DPX20021ZLDEX

Overview

The PI3DPX20021ZLDEX is a low-power, high-performance 20Gbps 4-channel Mux ReDriver supporting DisplayPort 2.0 UHBR20 transmission. It functions as a 2-to-1 multiplexer with four independent differential channels operating at 3.3V supply voltage across a -40°C to +85°C temperature range. The device features programmable equalization, swing, and flat gain to optimize signal integrity over various physical mediums by reducing intersymbol interference. It utilizes 100Ω differential CML I/Os and includes automatic receiver detect and adaptive power management for battery-sensitive applications.

Feature Summary

• Supports 20Gbps serial links with linear equalizer, fully compliant with DP 2.0 (UHBR20)
• Configurable 2-to-1 multiplexer with four independent differential channels
• Programmable receiver equalization, output swing, and flat gain via pin strap or I2C
• Adaptive power management feature to maximize battery life in consumer devices

Applications

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

Procurement Notes

Verify the ZLD package code corresponds to the 40-pin, 3 x 6 mm TQFN form factor. Confirm RoHS 3 compliance and Halogen/Antimony-free status if required. Check for AEC-Q qualification needs for automotive use. Ensure I2C address configuration matches system requirements using the 3-bit selectable address bits.

Selection Notes

Select this component for systems requiring 20Gbps bandwidth over DisplayPort interfaces. The 2-to-1 mux topology suits designs sharing one display source to two outputs. Verify that the 3.3V single supply voltage aligns with the platform's power rails. Consider the -40°C to +85°C industrial temperature range for environmental compatibility.
