Product details
Overview
PI2DPX2063AFLAEX from Diodes Incorporated is a 4-to-4 linear DisplayPort 2.1 ReDriver supporting UHBR20 (20 Gbps), UHBR13.5, and UHBR10 modes with 13.4 dB CTLE gain compensation, ultra-low latency (<300 ps), and integrated AUX channel listener for D3 power state management - deployed in high-bandwidth laptop docking stations and AIO PC motherboard DP2.1 signal integrity paths.
For engineers reviewing the PI2DPX2063AFLAEX datasheet, PI2DPX2063AFLAEX pinout, PI2DPX2063AFLAEX application, or PI2DPX2063AFLAEX equivalent, key selection criteria include UHBR20 equalization capability, per-channel I²C-programmable CTLE/flat gain, 1.8 V single-supply operation, industrial temperature range (–40°C to +85°C), and WLGA4528-32 package compatibility with high-density DP2.1 routing constraints.
Technical Context
The PI2DPX2063A implements four independent linear ReDriver channels with input-side CTLE equalizers (2.4–13.0 dB) and programmable flat gain (–4 to +2 dB), enabling precise channel loss compensation without retiming or protocol awareness. Its non-blocking architecture preserves pre-shoot and de-emphasis waveforms for system-level DFE coordination between DP2.1 source and sink.
Integrated AUXP/AUXN listener monitors AUX channel activity to autonomously trigger D3 low-power mode, while I²C slave interface (up to 1 MHz) allows real-time per-lane tuning of equalization parameters - critical for interoperability across UHBR20/UHBR13.5/UHBR10/HBR3 link training sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 20 Gbps per lane (UHBR20 compliant); enables full DP2.1 4-lane 80 Gbps aggregate bandwidth. |
| CTLE Gain Range | 2.4 dB to 13.4 dB; compensates up to ~30 dB channel loss at 10 GHz for FR4 trace lengths >15 cm. |
| Flat Gain Range | –4 dB to +2 dB; adjusts DC gain to optimize eye height without altering frequency response shape. |
| Latency | <300 ps; preserves timing alignment across all 4 lanes for synchronous DP2.1 link training and clock recovery. |
| Supply Voltage | 1.8 V ±5%; eliminates need for dual-rail supplies and simplifies PDN design in space-constrained DP interconnects. |
| Operating Temp | –40°C to +85°C; validated for sustained operation in laptop chassis and docking station thermal zones. |
| I²C Speed | Up to 1 MHz; supports rapid per-lane configuration during DP link training without stalling AUX channel handshaking. |
Pinout & Package
Package: 32-pin W-LGA4528-32 (2.85 mm × 4.5 mm, 0.4 mm pitch), lead-free and halogen-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4, B1–B4, C1–C4, D1–D4 | Differential Input/Output Pairs (CH0–CH3) | 4× DP lane I/O (TX/RX bidirectional); each pair routed differentially with 100 Ω impedance control. |
| E1, E2 | AUXP, AUXN | Dedicated AUX channel differential inputs; monitor AUX traffic to enable automatic D3 entry/exit. |
| F1, F2 | SCL, SDA | I²C slave interface; supports dynamic per-lane CTLE/flat gain register writes during link negotiation. |
| G1, G2 | HPD, VDDIO | Hot Plug Detect input and 1.8 V I/O supply; enables plug-and-play detection and level-shifted control signaling. |
| H1–H4 | VDD, GND | Four dedicated 1.8 V power pins; decoupled locally to suppress high-frequency noise from 20 Gbps switching. |
Key Features
| Feature | Design Value |
|---|---|
| Per-lane CTLE + Flat Gain Control | Independent I²C-programmable settings per channel allow fine-tuned equalization for asymmetric PCB trace losses. |
| AUX Channel Listener | Hardware-monitored AUXP/AUXN signals trigger autonomous D3 power-down without host CPU intervention. |
| Ultra-Low Latency Path | <300 ps propagation delay ensures minimal skew between lanes - essential for UHBR20 4-lane eye alignment. |
| Single 1.8 V Supply | Eliminates need for auxiliary 3.3 V rail, reducing BOM count and layout complexity in thin-profile DP2.1 interconnects. |
| Industrial Temp Range | Validated operation from –40°C to +85°C supports deployment in thermally aggressive docking station enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DP2.1 linear ReDriver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB546IRWBR | Supports UHBR13.5 max (13.5 Gbps); no AUX listener; fixed CTLE settings per lane. | Limited to DP2.1 UHBR13.5 systems; lacks autonomous D3 power management. | Select when UHBR20 is not required and system firmware handles power state transitions. |
| Parade PS8409A | Retimer architecture (not linear); adds ~2 ns latency; supports DP1.4a only (no UHBR20). | Requires full link training restart; incompatible with DP2.1 native UHBR20 handshake. | Select only for legacy DP1.4a designs where retiming is acceptable and UHBR20 support is unnecessary. |
Compared with TUSB546IRWBR and PS8409A, PI2DPX2063AFLAEX uniquely delivers UHBR20 linear redriving with hardware-assisted D3 entry, making it the only option for low-latency, power-aware DP2.1 20 Gbps interconnects in thermally constrained portable platforms.

FAQ
Does PI2DPX2063AFLAEX support DisplayPort Dual Mode (DP++), and how is it implemented?
Yes, PI2DPX2063AFLAEX supports DP Dual Mode via its transparent linear architecture and integrated AUX channel listener. It passes TMDS signals unaltered when operating in HDMI mode over DP++ ports, while maintaining full UHBR20 capability in native DP mode. The device does not require mode-switching logic - signal type is determined by source-side protocol negotiation, and the ReDriver regenerates both DP and TMDS waveforms identically.
What is the maximum supported PCB trace length for UHBR20 operation with PI2DPX2063AFLAEX?
At UHBR20 (20 Gbps), PI2DPX2063AFLAEX supports up to 15 cm of FR4 microstrip trace (4-mil dielectric, 5-mil width) with 30 dB insertion loss at 10 GHz when configured with 13.4 dB CTLE gain. Performance validation was conducted using standard IPC-2141A impedance models and confirmed with S-parameter-based channel simulations in the DS46006 Rev 3-2 datasheet.
How does the AUX listener function reduce system power consumption?
The AUX listener continuously monitors AUXP/AUXN differential voltage transitions without host processor involvement. When no AUX activity is detected for >100 ms, it asserts internal power-down sequencing, cutting active current from 160 mA to <10 µA. This enables immediate D3 entry during display idle periods, reducing average system power in laptops and docks by up to 120 mW per ReDriver instance.
Can PI2DPX2063AFLAEX be used in automotive infotainment systems?
PI2DPX2063AFLAEX is qualified for industrial temperature range (–40°C to +85°C) but is not AEC-Q100 qualified. Diodes Incorporated offers automotive-grade variants (e.g., PI2DPX2063AQ) with PPAP documentation, IATF 16949 manufacturing, and extended reliability testing. For automotive infotainment, use the Q-suffix variant - the FLAEX version is intended for commercial computing applications only.
