PI3DPX20012ZLDEX

Overview

The PI3DPX20012ZLDEX is a low-power, high-performance 20Gbps 4-channel DeMux ReDriver from Diodes Incorporated. It supports the DP 2.0 UHBR20 standard and functions as a 1-to-2 demultiplexer with independent channel configuration for receiver equalization, output swing, and flat gain. The device utilizes 100Ω differential CML I/Os and features automatic receiver detect, rate and coding agnostic operation, and transparent link training. It operates on a single 3.3V supply within a temperature range of -40°C to 85°C.

Feature Summary

• Supports 20Gbps serial links with linear equalizer for full DP 2.0 (UHBR20) compliance
• Functions as a 1-to-2 DeMux with four independent differential channels
• Features programmable equalization, swing, and flat gain via pin strapping or I2C control
• Includes adaptive power management and automatic receiver detect for signal integrity optimization

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 and halogen/antimony-free status requirements. Ensure I2C address bits are correctly configured if multiple devices share the bus. Check that the 3.3V supply voltage aligns with system power rails.

Selection Notes

Select this component when a 1-to-2 demultiplexing function is required for DisplayPort 2.0 signals up to 20Gbps. It is suitable for platforms needing to extend signals across cables or distant pathways while maintaining signal integrity through linear equalization. Consider the 40-TQFN package constraints for PCB layout.

Part Context

This part belongs to the PI3DPX series of ReDrivers designed for high-speed display interfaces. It complements other multiplexer/demultiplexer solutions by addressing UHBR20 data rates, enabling flexible signal routing in modern computing and gaming hardware architectures.
