Diodes Incorporated PI3EQX1014ZTFEX

Overview

PI3EQX1014ZTFEX from Diodes Incorporated is a USB 3.2 Gen 2 (10 Gbps) linear ReDriver IC with four independent 100 Ω differential CML I/O pairs, pin-adjustable receiver equalization and flat gain, and automatic receiver detect functionality. It operates from a single 3.3 V supply and supports signal integrity enhancement across PCB traces, cables, and switch fabrics in high-speed USB host-peripheral interconnects.

For engineers reviewing the PI3EQX1014ZTFEX datasheet, PI3EQX1014ZTFEX pinout, PI3EQX1014ZTFEX application, or PI3EQX1014ZTFEX equivalent, key selection criteria include differential data rate support (10 Gbps), CML I/O impedance matching (100 Ω), slumber-mode power management, equalization programmability, and UQFN-34 package compatibility with high-density USB routing layouts.

Technical Context

The PI3EQX1014 implements a linear analog ReDriver architecture-no retiming or protocol awareness-optimized for USB 3.2 Gen 2's 10 Gbps NRZ signaling. Each of its two ports comprises two fully independent differential channels, supporting bidirectional 10 Gbps lanes with programmable linear equalization to compensate for channel loss up to −15 dB at 5 GHz.

It features automatic receiver detection with a 7.3 ms idle timeout and transitions to slumber mode when no valid CML signal is present, reducing quiescent current to <100 µA per channel. The device uses pin-strapping (not I²C) for equalization level (4 settings) and flat gain (3 settings), enabling hardware-only configuration without firmware overhead.

Key Specifications

Pinout & Package

PI3EQX1014ZTFEX is housed in a 34-contact Ultra Thin Quad Flat No-Lead (UQFN) package, designated ZTF34, measuring 2.5 mm × 4.5 mm with 0.4 mm pitch and wettable flank terminations for automated optical inspection (AOI).

FAQ

Does PI3EQX1014ZTFEX require an external reference clock?

No. The PI3EQX1014ZTFEX is a linear ReDriver-not a retimer-so it does not use a reference clock or perform clock-data recovery. It amplifies and equalizes incoming CML signals directly, preserving native USB 3.2 timing and eliminating added jitter from CDR circuits.

Can PI3EQX1014ZTFEX be used with USB 3.2 Gen 1 (5 Gbps) signals?

Yes. The device is backward compatible with USB 3.2 Gen 1 (5 Gbps) and supports both data rates simultaneously across its two ports. Its equalization and gain settings remain effective at 5 Gbps, though less boost is typically needed due to lower frequency-dependent loss.

What is the thermal performance of the ZTF34 package under full 10 Gbps operation?

In typical 4-layer PCB layout with 1 oz copper and 2 internal ground planes, PI3EQX1014ZTFEX operates at ≤65°C junction temperature at 3.3 V and full 10 Gbps loading across all four lanes, meeting industrial ambient requirements without forced airflow or heatsinking.

Is PI3EQX1014ZTFEX compliant with USB-IF certification requirements?

Yes. The device is designed to meet USB-IF ReDriver compliance test plans for USB 3.2 Gen 2, including eye diagram mask testing, jitter transfer, and common-mode noise rejection. Diodes provides USB-IF test reports upon request for certified designs.
