Product details
Overview
PI3DPX1207CZHEX from Diodes Incorporated is a DP-Alt 1.4 / USB3.1 Gen2 linear redriver supporting up to 10 Gbps per channel, featuring non-blocking latency-free operation, built-in Aux switch, and independent EQ/gain/swing control for both DP and USB differential lanes. It enables transparent DisplayPort Link Training (LT) and supports cascaded redriver topologies for high-loss PCB traces or active cables in Type-C systems.
For engineers reviewing the PI3DPX1207CZHEX datasheet, PI3DPX1207CZHEX pinout, PI3DPX1207CZHEX application, or PI3DPX1207CZHEX equivalent, key selection criteria include DP1.4/USB3.1 Gen2 dual-mode signal integrity compensation, I²C-configurable equalization (up to 15 dB), 3.3 V single-supply operation, TQFN-42 package compatibility, and native support for DP Transparent LT without disrupting receiver DFE adaptation.
Technical Context
The PI3DPX1207CZHEX implements a fully analog linear redriver architecture with four independent DP/USB differential channels (2× DP + 2× USB), each with programmable input equalization, output swing (±10% step), and gain adjustment via pin-strapping or I²C (up to 1 MHz). It integrates an on-die Aux channel switch for Type-C SBU1/SBU2 routing and HPD detection logic.
Its non-blocking design preserves native DisplayPort Link Training handshake timing and allows receiver-side DFE adaptation to remain fully functional-critical for variable refresh rate (VRR) displays and adaptive sync applications. The device operates exclusively from a 3.3 V supply and includes auto power-saving mode triggered by signal loss detection.

Applications
| Notebook Systems | DP-Alt Monitors |
|---|---|
Use Scenario: High-resolution 4K@120Hz display output from thin-bezel laptop via Type-C port with internal trace lengths >8 inches.

Use Value: Enables compliance with DP1.4 spec over FR4 PCBs with >15 dB loss at 5 GHz, eliminating need for costly low-loss laminates. | Use Scenario: Embedded display controller in all-in-one desktop driving dual 4K panels using split DP/USB mode over single Type-C uplink. IC Role / Device Role / Timing Role: De-multiplexes and regenerates DP video and USB data lanes while maintaining independent gain control per protocol. Use Value: Supports simultaneous 4K@60Hz DP video + 5 Gbps USB3.1 Gen1 peripheral connectivity without signal degradation. |
| Active DP-Alt Cables | Desktop Docking Stations |
Use Scenario: 2-meter active Type-C cable with integrated redriver IC to extend DP1.4 bandwidth beyond passive cable limits. IC Role / Device Role / Timing Role: Cascaded redriver node that compensates cable insertion loss while preserving native LT handshake transparency. Use Value: Achieves full 10 Gbps per lane over 2 m length with <0.3 UI jitter increase-meets USB-IF and VESA certification requirements. | Use Scenario: Multi-port docking station aggregating DP Alt-mode video, USB3.1 Gen2 data, and PD negotiation over single upstream Type-C connection. IC Role / Device Role / Timing Role: Redriver and Aux switch co-located near upstream port to regenerate DP/USB signals and manage SBU routing for plug orientation. Use Value: Eliminates need for separate level shifters, muxes, and discrete redrivers-reducing layer count and EMI risk in compact dock PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DP-Alt redriver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB1046IRNQT | Protocol-aware retimer (not linear); requires DP LT re-initiation; supports USB3.2 Gen2x1 only | Lacks native DP Transparent LT; introduces ~12 ns latency; not suitable for VRR or adaptive sync | Select when USB3.2 Gen2x1 compliance and embedded retimer features (e.g., sideband signaling) are required over latency-critical DP video paths |
| Parade PS8408B | Linear redriver with 8 Gbps max (DP1.2/USB3.0); no integrated Aux switch; 32-pin QFN | Insufficient for DP1.4 10 Gbps; requires external SBU mux; limited equalization range (≤12 dB) | Select only for cost-sensitive DP1.2/USB3.0 applications where 4K@60Hz is sufficient and board space permits external aux routing |
Compared with TUSB1046IRNQT and PS8408B, PI3DPX1207CZHEX uniquely delivers true latency-free DP1.4/USB3.1 Gen2 linear redriving with integrated Aux switching-enabling seamless VRR, daisy-chainable links, and simplified Type-C system integration without protocol renegotiation or added latency.

FAQ
Does PI3DPX1207CZHEX require external termination resistors for DP or USB lanes?
No. The device integrates 100 Ω differential termination on all DP and USB receive inputs (CON_RX1/2P/N, AP_RX1/2P/N), eliminating need for external resistors. Transmit outputs are designed for direct connection to 100 Ω PCB traces or connectors without additional termination.
Can PI3DPX1207CZHEX operate in USB-only mode without DP functionality enabled?
Yes. Configuration pins CONF0–CONF2 or I²C registers allow disabling DP lanes while retaining full USB3.1 Gen2 redriver operation on AP_RX1/2P/N and CON_TX1/2P/N, with independent EQ/gain control per active lane.
What is the maximum supported insertion loss compensation at 5 GHz?
The PI3DPX1207CZHEX provides up to 15 dB of programmable equalization peaking, validated to compensate ≥20 dB of channel insertion loss at 5 GHz while maintaining <0.3 UI total jitter under typical operating conditions per VESA DP1.4 compliance test setup.
Is the thermal pad on the ZH package electrically connected or grounded internally?
The exposed thermal pad is electrically isolated and intended solely for thermal conduction. It must be soldered to a dedicated PCB thermal pad connected to a solid ground plane for optimal heat dissipation, but no internal electrical connection exists to any pin or supply rail.
