Product details

Overview

PI2EQXDP101-AZFEX from Pericom Semiconductor is a 1:1 DisplayPort™ 1.1a ReDriver IC supporting 4-lane operation at 2.7 Gbps per lane (10.8 Gbps aggregate), with programmable output swing (4 levels), pre-emphasis (4 levels), and automatic AUX-based link reconfiguration. It operates on dual supplies (1.5 V and 3.3 V), features 2 kV HBM ESD protection, and enables dual-mode DP/TMDS via AUX/DDC pass-through and CAD pin detection in notebook docking and embedded display interconnects.

For engineers reviewing the PI2EQXDP101-AZFEX datasheet, PI2EQXDP101-AZFEX pinout, PI2EQXDP101-AZFEX application, or PI2EQXDP101-AZFEX equivalent, key selection criteria include AUX-interpretive lane count/bandwidth control, low insertion loss on AUX path (0.35 dB @1 Mbps), HPD-triggered power-down, and 36-pin TQFN (ZF) package compatibility with high-density PCB layouts.

Technical Context

The PI2EQXDP101-AZFEX implements a fully autonomous AUX channel interpreter that decodes DPCD registers (00100h–00106h) to dynamically configure output swing, pre-emphasis, and active lane count without host CPU intervention. Its equalizer architecture compensates for channel loss while preserving signal integrity across long or lossy DP traces.

It supports both reduced bit rate (1.62 Gbps) and high bit rate (2.7 Gbps) modes per DisplayPort 1.1a, with jitter elimination achieved through adaptive training-path adjustment of drive strength and pre-emphasis. The device enters low-power mode when HPD is LOW or no data signal is present-even with an attached monitor-reducing standby current to 10 mA on VDD15 and 0.1 mA on VDD33.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	2.7 Gbps per lane (HBR), 1.62 Gbps per lane (RBR); enables full DisplayPort 1.1a compliance for UHD video transport.
Lane Count	Configurable 1/2/4 lanes via DPCD LANE_COUNT_SET register; supports scalable bandwidth allocation for embedded or portable systems.
Output Swing	4 programmable levels (340–1380 mV_pp); matches receiver sensitivity across varying trace lengths and connector losses.
Pre-emphasis	4 levels (0/3.5/6.0/9.5 dB); mitigates high-frequency loss in >15 cm FR4 traces without external tuning.
AUX Path Loss	0.35 dB @1 Mbps; preserves I²C/DDC timing margins during EDID reads and link training handshakes.
Power Supplies	Separate 1.5 V ±5% (VDD15) and 3.3 V ±5% (VDD33); isolates analog driver noise from digital logic rails.

Pinout & Package

PI2EQXDP101-AZFEX is housed in a 36-pin Pb-free & Green TQFN (ZF) package (5 mm × 5 mm × 0.8 mm), with exposed thermal pad (center pad = GND) for enhanced thermal dissipation in compact display interface modules.

Pin/Terminal	Circuit Role	Design Meaning
IN0± to IN3± (Pins 1–2,3–4,6–7,9–10)	Main Link RX differential inputs	Accept 4-lane DP input; support AC-coupled 100 Ω termination; tolerate 120–1500 mV_pp input swing.
OUT0± to OUT3± (Pins 19–20,22–23,25–26,27–28)	Main Link TX differential outputs	Drive 4-lane DP output with programmable swing/pre-emphasis; 50 Ω on-chip termination disableable per port.
AUX_SRC± (Pins 32–33), DDC_SCL/AUX+, DDC_SDA/AUX− (Pins 30–31,34–35)	AUX/DDR bidirectional channel	Pass-through AUX commands for link training; switch between DP (AUX±) and TMDS (I²C SCL/SDA) modes using CAD pin.
HPD_Sink (Pin 15), HPDSRC (Pin 13)	Hot Plug Detect interface	Monitor sink HPD status; assert source HPD to upstream GPU; enable automatic power-down when HPD = LOW.
CAD_Sink (Pin 14), CAD (Pin 12)	Cable Detect signaling	Detect DP cable presence via Pin 13 of DP connector; toggle ReDriver between DP and TMDS (HDMI) mode automatically.
VDD15 (Pins 5,11,17,21,29), VDD33 (Pin 36)	Power supply rails	Independent 1.5 V (analog/driver) and 3.3 V (digital/control) domains reduce cross-talk and improve jitter performance.

Key Features

Feature	Design Value
AUX Command Interpreter	Decodes DPCD registers (00100h–00106h) to auto-configure lane count, bandwidth, and pre-emphasis-no firmware required.
Dual-Mode DP/TMDS Support	Uses CAD pin to switch AUX/DDC routing between DisplayPort native mode and HDMI-compatible TMDS mode via same physical interface.
Adaptive Power Management	Enters low-power state when HPD is LOW or main link is idle-cuts VDD15 current to 10 mA and VDD33 to 0.1 mA.
Low-Loss AUX Path	0.35 dB insertion loss at 1 Mbps ensures reliable EDID reads and link training over extended AUX traces.
On-Chip 50 Ω Termination	Configurable per-port termination disable allows flexible layout options where external termination is preferred.

Equivalent & Alternatives

The following parts are listed as comparable options for similar DisplayPort ReDriver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TI TPD12S016	Integrated level shifter + ESD protection; no AUX interpretation; fixed 2.7 Gbps operation; supports only 2-lane DP.	Targeted at HDMI/DP dual-mode source-side protection, not link reconfiguration.	Select when ESD/clamp functionality is primary need and dynamic lane/swing control is unnecessary.
Diodes AP1361	Single-lane ReDriver; no AUX register parsing; supports only RBR (1.62 Gbps); no CAD-based TMDS mode.	Designed for cost-sensitive embedded displays with fixed low-bandwidth links.	Select for simple point-to-point DP extension where DPCD-based adaptation adds no value.

Compared with TPD12S016 and AP1361, PI2EQXDP101-AZFEX uniquely delivers full DPCD-aware link adaptation-including 4-lane HBR support, 4-level swing/pre-emphasis, and CAD-triggered dual-mode operation-making it the only choice for intelligent, self-configuring DP interconnects requiring minimal host software involvement.

FAQ

What is the function of the CAD pin on PI2EQXDP101-AZFEX?

The CAD (Cable Detect) pin (Pin 14) senses the presence of a DisplayPort cable via Pin 13 (CAD_Sink) of the DP connector. When asserted, it triggers internal logic to route AUX/DDC signals for native DP mode; when deasserted, it configures the device for TMDS (HDMI) mode by repurposing AUX pins as I²C SCL/SDA lines-enabling automatic dual-mode operation without host intervention.

Does PI2EQXDP101-AZFEX require external configuration registers or firmware?

No. PI2EQXDP101-AZFEX autonomously interprets DPCD registers (00100h–00106h) transmitted over the AUX channel during link training to configure lane count, bandwidth, output swing, and pre-emphasis levels. It has no power-on default state and requires no external I²C writes, GPIO control, or host processor involvement for basic operation.

How does PI2EQXDP101-AZFEX manage power states?

PI2EQXDP101-AZFEX enters low-power mode when HPD_Sink is LOW (monitor disconnected) or when no valid data signal is detected on input lanes-even if a monitor remains physically attached. Active current is 250 mA on VDD15 and 1.0 mA on VDD33; standby current drops to 10 mA on VDD15 and 0.1 mA on VDD33, reducing total standby power to 20 mW.

Can PI2EQXDP101-AZFEX be used in HDMI applications?

Yes-when configured in TMDS mode via the CAD pin, PI2EQXDP101-AZFEX routes DDC_SCL and DDC_SDA signals through AUX_SRC± pins, enabling HDMI source-side DDC communication. However, it does not perform HDMI protocol conversion or TMDS encoding; it serves strictly as a transparent DDC pass-through and signal conditioner for HDMI-capable DP sources using dual-mode transmitters.
